Abstract

This invention provides a C 60 This paper describes a SnO2 stack, its preparation method, and its application in perovskite solar cells, belonging to the field of perovskite solar cell technology. The preparation method includes the following steps: [The text then abruptly shifts to a different topic:] ...C... 60 The layer undergoes ozone or oxygen plasma surface pretreatment to obtain modified C. 60 Layer, in modified C 60 A SnO2 layer was prepared on the substrate to obtain C. 60 / SnO2 stack. This invention relates to C 60 The layer undergoes ozone or oxygen plasma surface pretreatment for C. 60 Modifying the layer with oxygen-containing functional groups facilitates the smooth, uniform, and dense growth of the deposited SnO2, thereby improving the fill factor, photoelectric performance, and long-term operational stability of perovskite solar cells. Furthermore, the preparation method is simple, easy to operate, and highly compatible with existing processes.
