Effect of Br Ions in Octylammonium 2D Perovskites for Performance Improvement of CuSCN-Based Perovskite Solar Cells
Source abstract
Abstract
Copper(I) thiocyanate (CuSCN) is among the most robust hole transport materials used in perovskite solar cells (PSCs). However, diethyl sulfide (DES), the solvent used for CuSCN, damages the 3-dimensional (3D) perovskite surface during the deposition of CuSCN, affecting photovoltaic performance. This study examined the effect of 2-dimensional (2D) perovskite formed on the 3D perovskite in suppressing DES damage. Octylammonium-based 2D perovskites containing greater amounts of Br exhibited high stability against DES dissolution and increased the power conversion efficiency of CuSCN-based PSCs from 14.2% to 17.0% and their photostability from 2 to 30 days.
