摘要：

由于具有成本低、工艺简单等优点,有机-无机杂化太阳能电池(PSCs)的研究和发展受到了广泛的关注,光电转换效率也快速提升到与传统晶体硅太阳能电池相当的水平。然而,PSCs稳定性差的问题严重限制了其商业化。在各种PSCs中,基于碳电极的无空穴传输层器件(C-PSCs)去除了影响稳定性的有机空穴传输层和金属电极,使得器件稳定性得到了明显的提高,是最具有应用前景的电池器件之一。自从2013年首次报道以来,C-PSCs的各方面研究取得了很大的进展,效率也从最初的6.6%提高到现在的15.9%。本综述将系统地介绍C-PSCs的最新研究进展,包括器件结构和工作原理、各部分研究进展(电子传输层、钙钛矿薄膜和碳电极),以及存在的问题和解决方案。

Abstract:

Due to the low-cost and simple fabrication processes, organometal trihalide perovskite solar cells(PSCs) have garnered recent interest in the scientific community, and their power conversion efficiencies have been rapidly increased to the levels comparable to traditional crystalline Si solar cells. However, the low stability of PSCs has obviously limited their commercialization. Among various kinds of PSCs, the one using carbon electrode(C-PSCs) as hole extraction electrode has shown the promise to address the stability issues because unstable hole transport materials were removed, while the carbon electrode is highly stable. Since first reported in 2013, much progress has been made on C-PSCs with the efficiency rapidly increasing from 6.6% to 15.9%. Herein, we have systematically reviewed the recent developments in C-PSCs, including device structure and working principles, progress on different parts of C-PSCs(electron transporting layer, perovskite layer and carbon electrode), and the issues needed to be addressed.

Key words: perovskite, carbon electrode, electron transporting layer, device structure, working principle
