【 摘 要 】

This report a novel and straightforward architecture of CaTiO3based solar cells with optimized hole transport material (HTM) properties. The perovskite CaTiO3 particle was prepared via the solution process using different CaCO3/TiO2 ratios. The design of CaTiO3-based solar cell follows the inverted architecture, in which poly (4-styrene sulfonate)-doped poly (3, 4-ethylenedioxy-thiophene (PEDOT:PSS) and PCBM-C70 were used as HTM and electron transport layer (ETL), respectively. Charge mobility of HTM was modified and improved by using either ethylene glycol (EG) or diethylene glycol (DEG). The optimum condition of CaTiO3-based solar cell was obtained using CaCO3/TiO2 ratio of (1:7) annealed at 900 °C and 44.4 % (v/v) DEG-modified PEDOT/PSS. The conversion efficiency of 3.1 % with a stable solar cell performance up to 72 h under the ambient condition without encapsulation was achieved.
