laptop Batteries: Thin film technology can be printed in foil board solar panels

Thin film technology can be printed in foil board solar panels

In the foil board printing cheap solar panels technology recently unveiled, which will become a milestone in solar energy industry.

Nano Solar technology is the key to copper, indium, gallium and selenium compounds sandwich, this is only the thickness of sandwich plate equivalent to the current use of solar PV market, one percent of the silicon plate. Impressed by the enormous potential of the technology of Google founders Sergey Brin and Larry • • Seji Page, from the technical development of early, two of the project to become angel investors.

Nano Solar achievements of the two statements the company's debut: The company has 40 billion dollars of contracts in hand, their capacity per watt of solar panels price of 1 U.S. dollar. This price and the current world-wide fossil fuel prices very competitive compared.

In particular, this technique can avoid building a huge power plant and nuclear power plants as the time of difficulties, the place was built in the neighboring city of many smaller solar power stations become another choice.

"Our products such as solar panels have a high return on investment can be configured from 2 MW to 20 MW of arbitrary choice. If consumption has increased sharply, so that the municipal power plant can be completed in six months, and directly transmission to the local power grid, without the need for large-scale transmission grid investment. "solar energy company's CEO Martin • Luosiqiesen in to the" Connection "Web site, wrote the message. "Thermal power and nuclear energy production and rapid return on investment can not even match it respect."

The solar technology is seen as a real "breakthrough" from the 20th century, since the early 80s, thin film solar technology has become the alternative energy research in the major areas of concern. Silicon cells are easy to produce, reliable performance, high efficiency, but some researchers believe that silicon cells have the inherent disadvantage. Production of silicon solar cells than thin film solar cells use silicon to more. And even if it can reach 40% of the photoelectric conversion rate, the efficiency is much lower than fossil fuels.

National Renewable Energy Laboratory has been committed to the nineties in the 20th century, the study of thin film solar, but it seems no technology other than in the laboratory of ridiculous. Really proved very difficult to produce thin film solar cells.

First Solar in 2005 with a cadmium telluride thin film solar cells reached the market. Rapid decline in their production cost, they also got a multi-billion dollar contract. Two days ago, they cooperated with the Chinese officials signed a two billion watts of contract. Now that the first solar energy company investors than the market value of American Airlines, Delta Airlines and the Federal Aviation sum of three even higher. First Solar has become the biggest obstacle Nano Solar and objectives.

Nano Solar and other companies the biggest difference is that they will bond the semiconductor technology in the metal foil is very special. Most companies require in a vacuum environment for a variety of operations, and Nano Solar solar cells can be directly printed on the foil.

"The difference between them and other companies is that they do not need to invent a solar panel manufacturing vacuum technology." National Renewable Energy Laboratory thin film solar researcher Miguel • Kang Teya said. "To be honest it seems very common, I should point out is that this wet-chemical technology for its investment in capital equipment to save a lot of money."

The large amount of solar cells cheap aluminum foil substrate, which is in raw materials and production advantages.

Earlier this year, First Solar announced that they began production price of less than 1 USD per watt of solar cells. Nano Solar said their prices can be lower. Nano is also a recent white paper will first solar energy company as a target, and claimed that their "system balance cost" (in addition to its solar panels than any other raw materials) lower.

For a company has not put into commercial production company that seems to be bragging about, but the company has 500 million dollars Nano venture capital and a number of cutting-edge technology in the hands. In addition they have won the contract, they also announced the National Renewable Energy Laboratory tests confirmed that the Nano's battery is the most efficient printed solar cells, conversion rate of 16.4%.

Even though solar energy is heating up competition between companies, in the expanding renewable energy market there are many market space. Market competition can promote technological progress and production costs, which advocates for solar energy is good news for them. The early nineties in the twentieth century, reduce the cost of solar energy production is mainly after the average cost of solar modules no longer had significantly reduced.

If you want the first solar energy company and a company like Nano solar companies continued to grow, they will reduce the average price of solar energy to compete with fossil fuel tank. First Solar will produce this year, one billion watts of solar panels. Nano's production is relatively small. They have solar panels can produce 640 megawatts of equipment, and production will also be in the current month on the basis of 1 megawatt gradually increase. Expand production by pervaporation technique may encounter some difficulties, but Luosiqiesen confidence.

"There are a lot of things put into operation, unless all the answers, or to one million batteries per month is impossible." He said, "This is why our production staff that from 0 to 1 MW from 1 trillion over the course of W to 100 MW of expansion is even larger challenges. "
