摘要

功率转换效率是太阳能电池组件广泛采用的关键因素。薄膜太阳能电池价格便宜,易于制造,但与晶体硅太阳能电池相比,其效率较低,需要改进。薄膜太阳能电池有两层吸收层(而不是只有一层),两层都有带隙能量梯度,可以在更宽的光谱范围内捕获太阳光子。在300 nm厚的CIGS~吸收层和870 nm厚的CZTSSe~吸收层中,如果带隙能量的分级是最优的,那么通过详细的光电模型可以预测效率为34.45%。

Double-absorber thin-film solar cell with 34% efficiency
Power-conversion efficiency is a critical factor for the wider adoption of solar-cell modules. Thin-film solar cells are cheap and easy to manufacture, but their efficiencies are low compared to crystalline-silicon solar cells and need to be improved. A thin-film solar cell with two absorber layers (instead of only one), with bandgap energy graded in both, can capture solar photons in a wider spectral range. With a 300-nm-thick CIGS~absorber layer and an 870-nm-thick CZTSSe~absorber layer, an efficiency of $34.45\%$ is predicted by a detailed optoelectronic model, provided that the grading of bandgap energy is optimal in both absorber layers.
