摘　　要：近年来,钙钛矿太阳能电池(Perovskite solar cells,PSCs)由于具有光伏性能优异、材料成本低、制造工艺简单等优势,引起了科研工作者广泛的研究兴趣。在PSCs中,电子传输层(Electron transport layer,ETL)在提取和传输光生电子方面起着至关重要的作用。氧化锡(SnO_(2))由于具有高光学透过率、高电子迁移率、良好的化学稳定性、合理的能级结构和可低温制备等优异性能,成为PSCs器件中理想的ETL。本文围绕SnO_(2) ETL在正置PSCs中的研究进展进行综述,首先介绍了SnO_(2)的结构与光电特性,并归纳了SnO_(2)的制备方法,随后对有机无机杂化PSCs及全无机PSCs中SnO_(2) ETL的改性进行了详细的阐述和总结,包括掺杂及界面修饰处理,最后总结全文,对SnO_(2) ETL的发展进行展望。In recent years,perovskite solar cells(PSCs)have attracted extensive research interest due to their excellent photovoltaic performance,low material cost and simple fabrication process.In PSCs,the electron transport layer(ETL)plays a crucial role in extracting and transporting photogenerated electrons from the perovskite layer to the cathode.Due to its high optical transmittance,high electron mobility,good chemical stability,good match with the energy level structure of the perovskite layer and the ability to be prepared at low temperatures,tin oxide(SnO_(2))has become an ideal ETL for PSCs.This paper reviews the research progress of SnO_(2) ETL in n-i-p PSCs,firstly,it introduces the structure and photoelectric characteristics of SnO_(2),and summarizes the preparation methods of SnO_(2).And then,the modification of SnO_(2) ETL in organic-inorganic hybrid PSCs and all-inorganic PSCs is elaborated and summarized in detail,including doping and interface modification.Finally,the full text is summarized and the development of SnO_(2) ETL is prospected.
