日本大阪大学基础工程学院研制成功一种具有19.1%高转换效率的 4mm~2的非晶硅太阳电池。新的太阳电池为不同材料连接型的串联结构的电池(碳化硅和多晶硅在下面的非晶硅太阳电池上沉积)。新电池有四个接点用来有效地吸收不同波长的光,并且能将许多光子导向下面的电池而实现高效率。研究者们用等离子化学气相沉积方法在近似250℃低温下产生太阳电池。晶体硅在下面的多晶衬 Osaka University, Japan Institute of Basic Engineering developed a 19.1% conversion efficiency of 4mm ~ 2 amorphous silicon solar cells. The new solar cells are tandem-structured cells of different material types (silicon carbide and polysilicon are deposited on the underlying amorphous silicon solar cells). The new battery has four contacts to effectively absorb light of different wavelengths, and can carry many photons to the underlying cell for high efficiency. Researchers use the plasma CVD method to produce solar cells at temperatures as low as approximately 250 ° C. Crystalline silicon polycrystalline lining below
