摘要：

The world's highest stabilized conversion efficiency of 9.5% has been achieved for a 30x40 cm(2) a-Si/a-SiGe glass superstrate solar cell submodule. However, significant optical loss still exists even in these high-efficiency a-Si solar cells. FEM numerical simulation has shown that the primary origin of the optical loss in textured a-Si solar cells at about greater than or equal to 800 nm is absorption in SnO2 which is enhanced by the optical confinement effect. Optical confinement also results in increased absorption in the metal electrode, which is another source of optical loss.
