Abstract

Based on a blended-interfacial-layer (BIL) with strongly coupled four components (FTO, SnO2, TiO2and perovskite), we demonstrate in this work the design of a more advanced electron transfer layer (ETL) for mesoscopic PSCs. For the new ETL, SnO2is a key component and is found to be essential to lower series resistance and enhance shunt resistance. Photovoltaic performance of PSCs using new ETL is much better than that of PSCs based on traditional ETL. In addition, the new ETL has been proved to be more advantageous in avoiding interfacial degradation and improving stability of the device.
