Perovskite solar cells (PSCs) have been developing rapidly since they were discovered, and their excellent photoelectric properties have attracted wide attention from researchers. The compact layer is an important part of PSCs, which can transport electrons and block holes. SnO₂ is an excellent and commonly used electron transport layer (ETL) material, and doping modification is an effective way to improve performance. Here, Zn with a similar radius to Sn has been introduced to the doping of the SnO₂ compact layer to achieve the purposes of conductivity enhancement of the compact layer and followed photoelectric performance improvement of the device. Zn-SnO₂ compact layers with different doping concentrations were prepared and applied to mesoporous architecture PSCs. When the doping content was 5%, the power conversion efficiency (PCE) of the device based on the Zn-SnO₂ compact layer has increased from 9.08% to 10.21%, with an increase of 12.44%. The doping of SnO₂ promotes its application in low-cost PSCs.

用于提高钙钛矿太阳能电池性能的掺锌 SnO2 致密层

钙钛矿太阳能电池（PSCs）自被发现以来发展迅速，其优异的光电性能引起了研究人员的广泛关注。致密层是 PSC 的重要组成部分，可以传输电子和阻挡空穴。SnO ₂是一种优良且常用的电子传输层（ETL）材料，掺杂改性是提高性能的有效途径。在此，在SnO ₂致密层的掺杂中引入了与Sn具有相似半径的Zn，以达到提高致密层的导电性和提高器件光电性能的目的。Zn-SnO ₂制备了具有不同掺杂浓度的致密层并将其应用于介孔结构 PSC。当掺杂量为5%时，基于Zn-SnO ₂致密层的器件的功率转换效率（PCE）从9.08%提高到10.21%，提高了12.44%。SnO ₂的掺杂促进了其在低成本 PSC 中的应用。
