摘要

为了优化铜铟镓硒薄膜太阳能电池的前电极，提高铜铟镓硒薄膜太阳能电池的效率，提出了一种可应用于铜铟镓硒薄膜太阳能电池的AZO/图案化Ag薄膜/AZO结构的前电极，中间层的Ag薄膜与电池顶层的金属栅线具有完全相同的图案和尺寸，并且位于金属栅线的正下方，这种新型结构可以提高电池前电极的电学性能，但对电池来说不会带来额外的光学损失。对比了新型前电极结构与几种传统前电极的电学和光学性能，并且制备了相应的电池进行了性能对比。实验结果表明，新型的前电极结构可以提高铜铟镓硒薄膜太阳能电池的短路电流，相对传统AZO电极，电池效率从13.83%提高到14.53%。本结构可以明显提高电池效率。

Abstract

In order to improve the efficiency of CIGS thin film solar cell

a novel AZO/patterned Ag/AZO multilayer front contact was investigated. In this architecture

middle Ag thin film is patterned

which has the identical shape and size with the metal grid of solar cell and under the metal grid. This architecture can increase the electrical properties when the transmittance is constant. The transmittance and sheet resistance of new architecture were compared with that of traditional front contact. In comparison with the solar cell with AZO and AZO/Ag/AZO front contact

the CIGS solar cell with new architecture shows the higher short circuit current and improves efficiency from 13.83% to 14.53%. The noval architecture can improve the efficiency of CIGS solar cell.
