Effects of n-type hydrogenated amorphous and microcrystalline silicon on p-i-n solar cells
Jiang Yeu-Long;Yan Yi-Su

N-type hydrogenated amorphous (n-a-Si:H) and microcrystalline silicon (n-μc-Si:H) were fabricated by plasma-enhanced chemical vapor deposition (PECVD). The influence of n-a-Si:H and n-μc-Si:H films on the performance of single n-layer and double n-layers p-i-n solar cells were investigated.

Multilayers i-layer p-i-n thin-film solar cells
Yeu-Long Jiang;Hsiao-Ku Shih

Hydrogenated amorphous silicon thin films with different silicon-hydrogen bonds of a-Si:Hx/a-Si:Hy multilayer structures and TCO/p/i(a-Si:Hx/a-Si:Hy)/n/Al p-i-n were fabricated by periodical modulation of RF power of plasma enhanced chemical vapor deposition (PECVD). Optimization of this thickness ratio can improve the I-V characteristics of the a-Si:Hx/a-Si:Hy multilayer p-i-n solar cells.

Crystalline Silicon PERC Solar Cell with Inverted-Pyramid-Like Surfaces and Ozonized AlOx Passivation Layer on the Rear Side
Pang-Kai Liu;Yu-Lun Cheng;Likarn Wang

A thin aluminum film on the inverted-pyramid-like surface of a silicon wafer was transformed into an aluminum oxide layer by the method of ozonation. Lifetimes of the wafers with such passivation layers proved to be increased, and the resultant PERC cells showed performance improvement compared with conventional counterparts.
