Fabrication and simulation of peroviskite solar cells comparable study of CuO and Nano composite PANI/SWCNTS as HTM

Abstract

Alternate CuO instead of Novel low-cost Polyaniline (PANI)-single wall carbon nanotubes (SWNT or SWCNT) nanocomposite—based hole transport materials (HTMs) as substitutes by thin film of CuO designed as HTM for the applications in Perovskite solar cells. The HTMs were prepared through a facile steps reaction from cheap starting material. These HTMs exhibit good solubility and charge-transport ability but it has big issue regarding temperature due to degrade the conductive polymer, in the same time using ZnO NW as ETM. The perovskite based on PANI-SWNTs achieved power conversion efficiency (PCE) of 5% under air conditions. For perovskite, we found that the solar cells synthesized based on vertical ZnO nanowire arrays by using perovskite organic materials of CH3NH3PbI3 as active absorber materials, Pani-SWNT enable better photovoltaic performance than using CuO as HTM theoretical study by using simulator SCAPS solar cells. These results show that using CuO instead of PANI-SWNTs-HTMs have great prospect to replace the Pani-SWCNTs which is the most widely used HTM to obtain high—stability devices with temperature.
