ULVAC market thin film silicon solar battery automatic detection device
Japan's ULVAC (ULVAC) announced, will be July 1, 2010 can automatically detect the series listed on thin-film silicon (Si) solar cell characteristics and TCO (Transparent Conductive Oxide) characteristics of the device "MPEC-opt1300". The company overall solution (Turn-Key Solution, to provide complete line of solar cells produced) as the center of business, which was launched in 2009 that can detect six kinds of thin film properties of a body unit "MPEC-1300". In addition to the membranous detection device outside, this also launched a unit automatically detects the device and TCO characteristics.
The production line of products for purposes of sampling inspection, can undermine the inspection unit features (shunt resistance and some other features can be non-destructive way to check), TCO properties can be checked separately by non-destructive testing. In solar cell production line after the performance evaluation process and final product inspection (solar simulator) used to resolve the problems found and reasons. As an option, but also with the results according to shunt resistor (resistor bad location information) of the laser repair, as well as the existing MPEC-1300 and the detection of MPEC-opt1300 unified data "Comprehensive analysis software . "
Features in the unit, originally from the formation of solar cells under the glass floor in the cut about 5mm square, to impose through its tin solder and insulate the electrode to produce called "mini-unit (Mini Cell)" a small piece components, then using irradiation or exposure to the elements the way of light, and features of the IV test. However, the formation of mini cell requires a lot of manual processing, and processing time is longer. ULVAC, said the original glass in the cutting needs of 180 seconds per point, per-point soldering, 300 seconds per test point to 75 seconds, such as 81-point test requires 750 minutes, 7 test takes 65 minutes.
And the device can not cut case of glass substrate, glass substrate using laser film formed on the silicon layer to be cut to form a mini-unit. As a result, the laser cutting each point only 30 seconds per test point just 40 seconds, in order to achieve a 81-point test requires 95 minutes, 7 points 7 minutes of the short detection test. Detailed characteristics of the unit test project, the conversion efficiency can short-circuit current, open circuit voltage, field shape factor, maximum power, shunt resistance and series resistance were detected.
In the TCO properties, the original need for cutting the glass floor of the damage inspection, and the device can be non-destructive way by a large area of haze characteristics (the ratio of scattered light) distribution for testing. Moreover, the detection time point only every 30 seconds. Defog degree features, it can also detect all the light transmission rate, diffusion rate and the parallel light transmittance transmittance. The unit price of 84 million yen (option). ULVAC will provide a package of solutions, the company's solar cell manufacturers as the main object, expand sales.
Existing MPEC-1300 has negotiated five or so orders, of which Taiwan will soon have a supply. The development of the MPEC-opt1300 also the first five year sales target. The goal "is a conservative estimate of thin-film solar cell manufacturers may also give priority to the flat panel display (FPD) and the crystalline solar cell investment, and defer investment in thin-film solar cells, so there may be a part of Taichung will be 5 next year in sales." (ULVAC Standard Products Division, East Japan Sales Minister Takeda clear).
Sony battery out of the behind the scenes appeared CIBF
Recently, Shenzhen, held the Ninth China International Battery Seminar / Exhibition (CIBF), which, as one of a small number of foreign exhibitors, Sony first unveiled its latest olivine lithium iron phosphate batteries, Sony energy component species Mao, chairman and president Shinichi also went to the show to learn more about the Chinese market and customers. Southern reporter in an interview to accept the first energy business, Sony revealed the latest move.
Reporters saw at CIBF, Sony is also the first time this exhibition showcased the latest research results --- the use of olivine lithium iron phosphate a new energy storage module. New energy storage module with 1.2 kwh level of capacity can be easily achieved through a parallel or series of high voltage or high-capacity energy supply in terms of security also has obvious advantages.
According to its introduction, low-carbon economy is the trend, starting from last November, Sony will be its battery business from behind the scenes to support e-business location into the foreground, and planning a one hundred billion yen (approximately USD 7.6 billion) in investment, as the new Sony's future business growth. Electric cars, all kinds of new energy power generation solutions in the battery market, is Sony's enclosure object.
According to Sony's new Business Development Department Planning Division to play peak-Ming, Minister Suzuki, power-storage solutions based on the new product can be used for fixed power, such as data server uninterruptible power system U PS wireless base station or mobile phone backup power supplies. As the energy storage module is highly scalable, next can be applied to a broader emerging areas such as home solar power system's energy reserves or electric vehicle power supply and so on.
In November 2009, Sony released Medium-Term Strategy Group, made a rare business plan for battery, proposed to take full advantage of Sony's battery technology for storage and other purposes to provide system solutions; research into electric car battery business. In February this year, Sony's new "cutting-edge battery development center", and strengthen existing energy business, and commercial battery electric vehicles to promote the development and commercialization.
Shinichi Mao said, according to species, Sony has had contact and some car manufacturers, including Chinese auto manufacturers, in order to achieve cooperation.
