摘要：

Textured surface of metal electrodes formed on a polymer film have been studied to take advantage of an optical confinement effect for hydrogenated amorphous silicon (a-Si:H) solar cell. Theoretical considerations and simulated experiments show that an inclination angle of the textured shape larger than 30° causes an optical confinement effect. The suitable textured Al surface was formed by controlling the crystallization of Al in a sputter-deposition process and adopted for back-side electrodes of stainless steel/Al/polymer. Consequently, the short-circuit current (Jsc) was improved by about 10% by using a textured Al layer with homogeneous roughness of 200-400 nm in size. For further enhancement of Jsc, this textured layer was adopted for multilayer electrodes such as Ti/Ag/Ti/Al, and ITO/p-i-n type solar cells formed on this multilayer electrode showed a high conversion efficiency of 11.28%. © 1990.
