초록

Traditionally, expensive metals like gold or silver have been used as the rear electrode for perovskite solar cells (PSCs), which have highly efficient performance. Within this framework, carbon nanotube (CNT) electrodes have been regarded as promising low cost electrodes due to their mechanical strength and excellent electrical conductivity. In spite of these advantages, concerns have arisen about the power conversion efficiency (PCE) and stability of PSCs based on CNTs due to the porosity of CNT electrodes and interfacial issue. In this work, we introduced PM6 hole transport material infiltration method to address issues related to the porosity of carbon nanotube (CNT) electrodes, aiming to improve the performances. As a result, the infiltration of PM6 into the CNT electrode improved the interfacial contact between the CNT electrode and the perovskite layer, thereby the best PCE of 15.49% was achieved in PSCs based on CNT rear electrodes.
