Abstract

Planar perovskite solar cells (PSCs) have surfaced as a promising photovoltaic technology due to their potential for low-temperature processing and streamlined fabrication. A key factor in enhancing the performance of planar PSCs is the electron transport layer (ETL). This study explores the use of WS2, a transition metal dichalcogenide (TMDC), as an alternative ETL in the methylammonium lead iodide (MAPbI3) active layer planner n-i-p structured perovskite solar cells. Numerical investigation using wxAMPS software evaluates the feasibility of WS2 as a replacement for conventional ETLs, addressing challenges related to toxicity and stability. To optimize device performance, comprehensive simulations analyze the effects of various parameters, including ETL thickness, hole transport layer, absorber layer, doping concentration, defect density, and bandgap. The optimal thickness and the band gap value of the WS2 ETL layer have been reported to be 150 nm and 1.8 eV, respectively. The optimized configuration achieves performance metrics as follows: a power conversion efficiency of 26.34%, a fill factor of 82.84%, a short-circuit current density of 22.7 mA/cm² and an open-circuit voltage of 1.41 V. These results underscore the potential of WS2 TMDC-ETLs for high-efficiency PSCs, paving the way for practical applications following experimental validation.
