Abstract：
Metal-halide perovskite solar cells (PSCs), an emerging technology for transforming solar energy into a clean source of electricity, have reached efficiency levels comparable to those of commercial silicon cells. Compared with other types of PSCs, inverted perovskite solar cells (IPSCs) have shown promise with regard to commercialization due to their facile fabrication and excellent optoelectronic properties. The interlayer interfaces play an important role in the performance of perovskite cells, not only affecting charge transfer and transport, but also acting as a barrier against oxygen and moisture permeation. Herein, we describe and summarize the last three years of studies that summarize the advantages of interface engineering-based advances for the commercialization of IPSCs. This review includes a brief introduction of the structure and working principle of IPSCs, and analyzes how interfaces affect the performance of IPSC devices from the perspective of photovoltaic performance and device lifetime. In addition, a comprehensive summary of various interface engineering approaches to solving these problems and challenges in IPSCs, including the use of interlayers, interface modification, defect passivation, and others, is summarized. Moreover, based upon current developments and breakthroughs, fundamental and engineering perspectives on future commercialization pathways are provided for the innovation and design of next-generation IPSCs.
摘要：
金属卤化物钙钛矿太阳能电池（PSC），一种将太阳能转化为清洁电力来源的新兴技术，已达到与商业硅电池相当的效率水平。与其他类型的PSC相比，倒置钙钛矿太阳能电池（IPSC）由于其易于制造和优异的光电性能而显示出商业化的前景。层间界面在钙钛矿电池的性能中起着重要作用，不仅影响电荷转移和传输，但也可以作为防止氧气和湿气渗透的屏障。在这里，我们描述并总结了最近三年的研究，这些研究总结了基于接口工程的IPSC商业化的优势。本文简要介绍了IPSCs的结构和工作原理,并从光伏性能和器件寿命的角度分析了接口对IPSC器件性能的影响。此外,全面总结了各种接口工程方法来解决IPSC中的这些问题和挑战，包括夹层的使用，接口修改，缺陷钝化，和其他人,是总结的。此外，根据当前的发展和突破，为下一代IPSC的创新和设计提供了未来商业化途径的基础和工程观点。
