无机钙钛矿太阳能电池研究进展

Research Progress of All-Inorganic Perovskite Solar Cells

钙钛矿太阳能电池是一种新兴的全固态平面型太阳能电池,从2009年第一次出现到现在发展迅速。据报道,有机-无机杂化钙钛矿太阳能电池的光电转换效率已超过23%,全无机钙钛矿太阳能电池的光电转换效率也超过17%。相比于有机-无机杂化钙钛矿太阳能电池,无机钙钛矿材料由于热稳定性好而成为钙钛矿太阳能电池研究领域的热点之一。本文主要综述了全无机钙钛矿太阳能电池的基本知识及最新的研究成果,尤其是提高全无机钙钛矿太阳能电池的效率及稳定性方面的成果,对钙钛矿薄膜层的改进、电子传输层及空穴传输层优化方面的成果作了详细的介绍和评述。

Perovskite solar cells is a kind of emerging all-solid-state planar solar cell and grew rapidly since its first appearance in 2009. It was reported that the photoelectric conversion efficiency of organic-inorganic hybrid perovskite solar cells has exceeded 23%, and the photoelectric conversion efficiency of all inorganic perovskite solar cells exceeded 17%. Compared with organic-inorganic hybrid perovskite solar cells, the thermostability of inorganic perovskite materials was higher, which makes it a hotspot in the research field of perovskite solar cells. In this paper, the latest research progress of all-inorganic perovskite solar cells was mainly reviewed, especially the improvement of the efficiency and stability of the all-inorganic perovskite solar cell types. The improvement of the perovskite film layer, results of optimizing the electronic transport layer and hole transport layer were described and reviewed in detail.
