Project Name: Ultrathin PTAA Layer and Phenylhydrazinium Iodide for Defect Passivation and Enhanced Charge Carrier Mobility in Perovskite Solar Cell

Project Leaders: Abdullah Al Maruf

Chapter Advisors: Robert McTaggart

Project Description: In recent years, hybrid perovskite solar cells (HPSCs) are of great interest in the scientific community due to their impressive photovoltaic performance and low-temperature solution processing capability. This project is devoted to developing HPSCs with a novel material, phenylhydrazinium iodide (PHAI), as an additive in FAPbI3 perovskite, as well as introducing an optimally designed ultrathin poly(triarylamine) (PTAA) layer in the stacks of HPSC – to solve two of the crucial problems in HPSCs, low carrier lifetime and interfacial recombination, affecting the solar cell’s power conversion efficiency and stability. South Dakota State University’s (SDSU) SPS Chapter will lead this research project, which will potentially help to solve the current limitations of next generation solar cells, as well as train undergraduate students in rigorous experimental and computational physics research.
