论文摘要
太阳能电池是半导体设备，在照明时通过电荷产生发电。为了获得最佳的设备效率，照片生成的载体必须在重组之前到达电气接触层。对重组过程和运输行为的深入了解对于设计更好的设备至关重要。卤化物钙钛矿太阳能电池通常由多晶的吸收层制成，但在晶界的性质和作用上没有共识。这篇评论论文涉及对扩展缺陷进行调查的理论方法。我们在卤化物钙钛矿太阳能电池中介绍了有关晶界的最新计算研究及其对点缺陷分布的影响。我们以讨论未来的研究方向结束了本文。
Solar cells are semiconductor devices that generate electricity through charge generation upon illumination. For optimal device efficiency, the photo-generated carriers must reach the electrical contact layers before they recombine. A deep understanding of the recombination process and transport behavior is essential to design better devices. Halide perovskite solar cells are commonly made of a polycrystalline absorber layer, but there is no consensus on the nature and role of grain boundaries. This review paper concerns theoretical approaches for the investigation of extended defects. We introduce recent computational studies on grain boundaries, and their influence on point defect distributions, in halide perovskite solar cells. We conclude the paper with discussion of future research directions.
