Lifetime spectroscopy of impurities in silicon solar cells

硅太阳能电池中杂质的寿命谱。该项目旨在将最近开发的实验技术应用于表征硅中杂质的重要问题，重点关注太阳能电池应用。这些基于载流子寿命测量的新光谱技术比大多数现有方法更灵敏且更不模糊。这些结果将在两个独立的方面对太阳能电池技术产生重要影响-首先，通过允许对标准硅太阳能电池中的性能限制杂质进行准确诊断-其次，通过识别可以通过杂质光伏效应提高电池性能超过常规限制的特定杂质。

Lifetime spectroscopy of impurities in silicon solar cells. This project aims to apply recently developed experimental techniques to the important problem of characterising impurities in silicon, with a strong focus on solar cell applications. These new spectroscopic techniques, which are based on carrier lifetime measurements, are more sensitive and less ambiguous than most existing methods. The results will have important implications for solar cell technologies in two independent ways - firstly, by allowing accurate diagnosis of the performance-limiting impurities in standard silicon solar cells - and secondly, by identifying particular impurities which could boost cell performance beyond the conventional limit through the impurity photovoltaic effect.
