Advantage

It was and is straight from the box and very friendly. The display has excellent color quality, everything looks clear. The speakers are great, everything seems very clear to them. Very good everything. very good speakers, very fast.

High performance and not stop once froze or not. Internet and other windows open simultaneously, and the computer will slow down at all. The screen is very bright and clear, are the ports is very good. basic computer with far more power than expected. You get a little more than what you paid.

improve their capabilities to wireless devices affordable for its basic operation. This team is definitely worth the money.

This machine has everything you need in a laptop that is used for lighting. It has a large, bright and clear. Very lively. It is very fast too. Our Internet e-mail appears immediately and without hesitation. The presentation is very easy to fix and the camera is very good too.

Disadvantages:

No reliable, always hard freezes, the system periodically close on themselves, are not really impressed by Anthlon or Vista. It is the fact that Anthlon.

With the AMD Athlon Processor could not handle more than two or three windows open at once after the problems increasingly not know if it was just the beginning Processor. It has an AMD processor, which is good and bad. The system is so funky with XP and install Windows Vista on it.

Play music files with the factory installed Windows Media Player is often interrupted without parallel processes. In built-in speakers do not use after two weeks. Disappointed that Windows XP is not available.

The Inspiron has been a little slow, but if you upgrade the store and go to a bigger hard drive to be ineffective. If you’ve tried a few programs at the same time, it freezes, use a little.

Battery

6-cell dell inspiron 1501 battery, which could get 3 hours and 25 minutes remaining. This was at half screen brightness and Wi-Fi off. More than 3.5 hours, I leave it idle was at about half the time, and half the time I rip things like a CD, run benchmarks and tested various programs. Overall, I was sufficiently impressed to get the battery life, for example. As a portable 15.4 “ is probably not a ton and do not want 4 + hours battery life. However, there is an option to upgrade a battery of nine cells must be 4 + hours battery life. The 9-cell battery is flushed with the back of the laptop and not exceed. The tester is equipped with a 85 WH (7600 mAh), 9-cell lithium-ion laptop battery, which is available to provide an additional. The investment is worth it, because this battery has a long 50%.

Concept of reorganization may be appropriate to focus

Xianyang Deflection main deflection coil, the product used for traditional TV. Past two years, subject to the impact of flat-panel TV, the traditional TV market shrinking dramatically. Following the 2007 losses, Xianyang deflection notice a loss in 2008 is expected to be 5,000 million, and actively promote the reorganization of assets to reverse the situation to become deflecting Xianyang key concern is the controlling shareholder of Xianyang City in March 2008 the SAC had Chemical Industry Co., Ltd. and Shaanxi Shenmu restructuring agreement of intent signed, and Shaanxi Shenmu Chemical Industry Co., Ltd. is a large modern coal chemical enterprises of methanol, is China's largest methanol production base of processing and strength, once the success of the reorganization will give the company brought about radical changes and great opportunities for development, although restructuring has not yet reached, the uncertainty of a strong, but the reorganization is still subject to a certain degree of short-term opportunities.

Acceleration is still pulled up space

Secondary market, the stock battery with a new energy concepts and the expected reorganization of assets, funds a high degree of concern, shares of the unusually active, experienced a technical point of view and despite a certain level rise, but the volume change is very modest, indicating higher levels of the main control disk, short-term longs took a decisive advantage, market outlook is expected to accelerate the move up, there is still much space.

We are concerned about solar cells in 2009

We are concerned about solar cells in 2009

In the solar power system, the technology of the most complex part of the claim to be a solar cell. Solar power system solar cells is the core part of its development, production will directly affect the popularity and development of solar power.



The principle of solar cells can have the sun light in the semiconductor pn junction to form a new hole - electron pairs in the pn junction electric field, the hole flow from the p-n area, the flow of electrons from p-n area, then through the circuit after the formation of current. Solar power generation solar power in two ways, one is light - heat - electricity conversion, and the other is light - electric direct conversion.

Tokyo, Japan in 2008, a solar show, a Japanese Industrial Technology Research Institute's staff show flowers and leaves are made into the shape of the solar cell model.



Review of the global development of solar cells



As early as 1839, French scientist Becquerel (Becqurel) discovered that light can make semiconductor material between different parts of the potential difference. This phenomenon became known as the "photovoltaic effect", referred to as "photovoltaic effect." In 1954, U.S. scientists Qiabin and Pirson Bell Laboratories in the United States made the first practical silicon solar cells, the birth of the solar energy into usable electrical energy photovoltaic power generation technology.



Since then, increasing the types of solar cells, growing a wide range of applications, and gradually expand the size of the market. To 1994, the world has reached sales of 64 megawatts of solar cells, showing the rapid development trend. In this century, some developed countries have developed, including solar cells, including the development of renewable energy projects. Research and production of solar cells in Europe, the Americas, Asia a large-scale roll out. Compete for the United States and Japan the world PV market dominance, introduced competing solar technology research and development projects. In recent years, production of solar cells worldwide average annual increase of nearly 40% of the total world production in 2003 has reached 744 MW.



Types of solar cells



According to the different materials used in solar cells can be divided into: 1, silicon solar cells; 2 to inorganic III-V compounds such as gallium arsenide, cadmium sulfide, copper indium selenium compounds such diverse materials of the battery; 3, features high Preparation of large molecular solar cells; 4, nanocrystalline solar cells.



Silicon is the ideal solar cell material, which is silicon-based solar cells to the main reason. In these cells the highest conversion efficiency of silicon solar cells, the most mature technology photoelectric conversion efficiency up to 23.3%. In the production process, the general texture of the surface, emitter passivation, area doping technology. However, due to silicon material prices and the corresponding impact complicated process, the cost of high price of silicon, dramatically reducing the cost is very difficult, can not achieve the massive popularity of solar power.



With the continuous development of new materials and related technology, in other village-based solar cell materials have shown more and more attractive prospects. The international low-cost mass production technology research focused on polycrystalline silicon, amorphous silicon large area thin film, CdTe cells, CIS cells manufacturing technology, Ⅲ-V compound semiconductors and efficient solar cells, amorphous silicon and crystalline silicon thin film photovoltaic cell hybrid and so on.



If silicon is characterized by high efficiency, high cost, the problem of other materials is undoubtedly the low-cost battery, transforming weak. Compared with the single crystal silicon solar cells, in addition to silicon, cadmium telluride loaded with other materials, the photoelectric conversion efficiency of the battery generally does not exceed 15%.



The development of solar cells



Began to study in China in 1958, solar cells, first used in 1971, China launched a satellite. 1973 will be used for terrestrial solar cells. As a result of price and output restrictions, market development is very slow, except as satellite power, solar cells on the ground only for a small power supply systems, such as beacon lights, railway signal systems.



In 2002, the state ministries launched the "Western Provinces Rural without electricity power scheme", by PV and small wind power to solve seven provinces in the western town without electricity electricity problems. The start of this project greatly stimulate the solar power industry, China has built several solar cell packaging line, so that the production of solar cells is increasing rapidly.



At present solar cells already widely used in communication, transportation, consumer products and other fields, the inclusion of photovoltaic power generation not only to national research programs, and included in the national electric power construction program, but also in a number of major projects in the applications. The end of 2003, China's total installed capacity of solar cells to 5 thousands. At present, the photovoltaic power generation has been throughout the western provinces of China, and parts of central and eastern provinces, municipalities and autonomous regions, the total size of investment has more than 30 billion yuan.



Efficient and cheap solar cells unity has always been the goal of international development. And the same, our products, promote the fundamental problem assembly here. Grasslands, islands, deserts and other areas without electricity huge demand, but the price affordability, lack of production scale and product specific weaker and other issues is very conspicuous. Power system in the city, the high cost of investment is no doubt one more product promotion more difficult. Therefore, improve efficiency, reduce costs and expand the scale of development should be present, production of solar cells subject.



In 2008, the global financial crisis also spread to China's solar cell industry, polysilicon prices fall to record low competition level of play, the original "blue skies" of the solar cell industry, all of a sudden "dark clouds", the crisis had led many companies to cut production layoffs and other ways to deal with, but I believe that the use of solar energy photovoltaic power generation is irreversible trend. China has become the world's second largest after the U.S. consumer market, electric power demand growth rate was highest in the world. The tension of oil energy, coal resources make the existing emergency power generation can not meet the power consumption, the promotion of solar energy demand in China is still a pressing need, the market potential is huge. For the market to accelerate the development of solar cell industry will have bright prospects.

Dell Inspiron E1505 Laptop Review

Dell Inspiron E1505 Laptop Review

The E1505 is Dell Inspiron with 15.4-inch widescreen display with the impressive new Intel Core Duo CPU. A virtually identical Inspiron 6400 is through its enterprise portal. On the outside, as it replaces the Inspiron 6000 looks like, but the new hardware inside makes for impressive performance. In the traditional style of the Dell E1505 is well rounded, very personal and is available to offer a competitive price, but not all the radicals.

The E1505 has been reviewed here configured as follows:

* Intel Core Duo T2500 2.0 GHz memory.

* 15.4 "SXGA + UltraSharp TrueLife

* 512 MB DDR2 533 MHz RAM in dual channel mode

* Integrated Intel Graphics Media Accelerator 950

* 100GB 5400RPM SATA hard drive

* 8x DVD + / - Dual Layer Recording

* 53 Watt-hour battery 6 cell

Construction and Design

The Inspiron E1505 is for most of the Dell lineup white lacquer and covered with a cut to black. I’m not a fan of the painted surfaces, as they seem to be more prone to scratches and chips. The color palette is simple, but I’m not a big fan of the white trim "bumpers."

The notebook is sturdy enough to be comfortable lifting it by one corner. However, I want to create better quality products. Is comparable to Sony and others, but not in the vicinity of the solid (and expensive) IBM ThinkPad line. Like my Inspiron 9300, there is a gap in the bottom of the LCD. This region is also very hot. It is when the backlight or inverter is.

The screen is very sharp with nice saturated colors and high contrast. The performance of the E1505 He was really a surprise. There is no doubt that the Core Duo is fast. The 5400 large disk with a good performance, even if a disk of 7200 rpm would be even better and maintain a level of interest, with the fast CPU and load programs faster.The Dell E1505 is calm notable - the most time. The touchpad is slightly recessed feel so it’s hard to go wrong. The two buttons are quite cheap, but respond well. The Dell Wireless 1390 802.11g signals of good and with a variety of wireless LANs. Yes, also in Fairbanks, Alaska, have hot spots.

Battery

With the smaller option 6 cell battery and a powerful processor, I had high hopes for the life of the battery. However, the Dell lasted longer than expected. At maximum brightness, played a DVD of 2 hours and 30 minutes. Under normal light tasks, with WiFi on and almost maximum brightness, the battery lasted nearly three hours. Attenuation of the screen and open wireless expressed almost four hours of total autonomy. I had the battery in 90 minutes or less to burn, if you really tried. Game likely to burn this fast.

The optional 9-cell dell inspiron e1505 battery, which is the same physical size of the 6-cell should be approximately 50% longer to execute.

The battery charges fast for the first 80%. With about 1% per minute, you can make an important boost for an hour on a scale at the airport.

A larger battery could be used a better choice than two batteries. wear lithium ion battery, although not in use.

---

Dell Inspiron E1505 review portable entertainment now an Intel Core 2 Duo. Although still a poor choice for the Games of the E1505 is much stronger for other applications, including music and photo editing and video playback. The book also sheds 6.9 E1505 good enough speakers, dedicated media keys and a comfortable keyboard with stylish white trim, if you have a great choice for all consumers who do not want to get an arm and a leg to get a desktop replacement.

Price of solar cells or bottom out

Price of solar cells or bottom out

Solar cells from the 4th quarter, began to cut production, the recent play seems to gradually cut overall effect, prices began to have stabilized, customers are asked about signing an increase in the frequency of a phenomenon, but solar industry said, because the prices close to low water level, current price contract to worry about the price rebound in 2009, but in a wait and see attitude.

Solar subsidy policy by the Spanish exchange in September and the financial turmoil, the two sides thereof facing the solar industry, orders for instant shrink dilemma facing the 4th quarter of unprecedented proportion of high inventories and cut-off, many small solar cells Factory 11,12 revenue contribution is minimal, and substantially cut the other side of the wave of layoffs is not stopped.

Continuing pressure to enlarge the environment, coupled with the financial turmoil caused by the financing, the price of solar cells fell sharply rare show from the August peak of the highest per-watt shouted 3.5 to 3.8 U.S. dollars, to 12 months outcry spacing of continually expanding, 2.1 ~ $ 3 per watt, the water level has a turnover of examples, highlighting the market clutter.

But 2.1 to $ 2.2 per watt, low price of water, solar-cell factory for most purposes are bottom of the price, if the source material procurement costs are not competitive, then the price of losing money is more likely the water level, in consideration of the new polysilicon material sources out of the situation is still poor, the source material prices fall again space is limited, therefore the price hit bottom solar cells, recently has attracted many of the module factory initiative to ask, hoping to sign at this price in a single year in 2009 contract.

Motech that appears in late December, the battery tends to decline in value does have a smooth trend, but their prices Motech level remained at 2.4 to 3 dollars per watt, the current prices are still unable to accept the low water level, in particular, Many signed their long, in fact, the price level are quite good, the quality requirements of the client better than the price gap.

Yi Tong pointed out that late December price decline in the battery does have the phenomenon of stabilization, which should be attributed to solar-cell factory in Taiwan to quickly adjust production capacity caused by the recent initiative to ask the client to sign a short about 1 year did increase the frequency, but consider the price of a rebound in 2009, the opportunity is still waiting to see, do not intend to rush contract, resulting in loss of future unnecessary post.

Solar industry said the price bottomed out yet wait and see but the demand stabilized, so the industry will continue as both sides expected the order to determine the capacity of the hands of utilization rate, estimated the short term will help to increase the stability of prices.
