Abstract

In recent years, perovskite (CH3NH3PbI3-XClX) solar cells have been studied steadily due to their potential properties: low-cost processing and possibility to produce large area by low temperature processes. The perovskite film used as light absorber is obtained by solution process and has a crystalline structure. Many different solvents are being developed and gradually adopted for high-performance inorganic-organic hybrid perovskite solar cells. PEDOT:PSS and PC60BM are used as hole transport layer (HTL) and electron transport layer (ETL), respectively. The size of active area is 0.28cm 2. In this study, 9.54% of power conversion efficiency (PCE) is obtained with a saturated current density (Jsc) of 15.03 mA/cm 2. The degradation of the performance of the solar cell is studied with XRD measurements as well as electrical characterizations. The perovskite solar cell performance decreases with aging time (Table 1 and Figure 1a) and XRD data show the growing of the PbI2 peak and a decreasing of the CH3NH3PbI3 (MAPbI3) peak.
