As the world's leading thin-film silicon photovoltaic production equipment supplier Oerlikon Solar today announced that its amorphous silicon (a-Si) single-junction photovoltaic cells gained a new record of stability and conversion efficiency. Recently by the U.S. National Renewable Energy Laboratory (NREL) re-affirmed and recognized the test results show that the energy conversion efficiency of more than 10%. The results of the amorphous silicon thin film photovoltaic technology to create a new world record. Oerlikon Solar in Neuchatel R & D team can consistently produce a high similar to the efficiency of solar cells, demonstrating a stable and repeatable process.
"The achievements are impressive demonstration of the rapid promotion of Oerlikon Solar thin-film silicon PV technology to reduce electricity costs unique ability," Jeannine Sargent, CEO Oerlikon Solar said. In the amorphous silicon technology to obtain a high cell conversion efficiency is a proprietary high-performance amorphous silicon and microcrystalline silicon cells laminated photovoltaic technology a key driver.
A record of solar cells to demonstrate the superior performance of the Oerlikon advantages of thin-film silicon photovoltaic technology, once again demonstrates the company's integrated research and development planning. Oerlikon Solar's advanced deposition equipment and technology and its large number of process know-how eventually to create a higher conversion efficiency of solar cell design optimization. The recent success of amorphous silicon cell efficiency has laid a-Si modules laminated acquired or produced more than 10% efficiency basis.

Sanyo developed a thickness of only 0.1 mm thin film solar cell efficiency
According to Japan's Kyodo News agency reported that Japan's Sanyo Electric Co. announced the 18 developed only half of its original thickness, about 0.1 mm of solar cells. The battery-piece basic components of solar cells, solar energy conversion rate reached the highest level of 22.8%. Sanyo hopes to mass production a few years later, when the solar power system is expected to push prices down.
Solar panels from a combination of solar cells. The existing ordinary cell thickness of about 0.2 mm, and the cell thickness of only 0.098 mm. Usually the battery thickness thinning will reduce the amount of light absorption, resulting in current and voltage goes low, the output power decrease. However, according to Sanyo's introduction, by improving the bonding technology to improve the absorption effect by preventing the decline in power output.
Thin film batteries will allow the use of silicon raw materials, reduced by about 25% lower costs help drive down the price of solar panels. In addition, the battery can also be adjusted to expand the use of film curvature. Sanyo announced in May of this year developed the world's first solar energy conversion rate (23%) of solar cells.
