摘要

本文研究了不同碱掺杂策略对kesterite Cu2ZnGeSe4吸收材料的影响，包括对半导体材料结构和形态特征的影响，以及对太阳能电池器件光电性能的影响。所研究的碱元素包括Li, Na和K，主要通过沉积后处理(PDT)和预吸收剂合成(PAS)两种方法引入。本研究表明，PDT策略比PAS更有趣，Li是进一步提高Cu2ZnGeSe4器件性能的最佳碱候选者。

Effect of Alkali Doping Strategies on the Performance of Wide Band Gap Cu2ZnGeSe4 Thin Film Solar Cells

In this work, the effect of different alkali doping strategies in kesterite Cu2ZnGeSe4 absorbers is studied, including the impact on the structural and morphological characteristics of the semiconductor material, and the optoelectronic properties of the solar cell devices. The studied alkali elements include Li, Na, and K, and are introduced by two main approaches: post-deposition treatment (PDT), and pre-absorber synthesis (PAS). This study shows that PDT strategies are more interesting than PAS, and Li as the best alkali candidate for the further improvement of Cu2ZnGeSe4 devices performance.
