In this work, Zn2SnO4(ZTO) single crystal were preparaed by hydrothermal process. The particle sizes and morphology of ZTO were controlled by time. After 16 h of hydrothermal treatment, Zn2SnO4 particles with a particle size of 10-30 nm could be obtained. PL, TRPL, EIS and IMPS were utilized to study the performance of ZTO layers and the results showed that ZTO layers in the battery had better charge extraction and transmission ability compared with TiO2 layers. Finally, Perovskite Solar Cells based on ZTO displayed excellent current density and the PCE of can reach 18.32%. (C) 2020 Elsevier B.V. All rights reserved.
