Boosting the performance of PBDB-T/ITIC based organic solar cell: A theoretical analysis utilizing SCAPS-1D

Abstract

Solar cells have become the centre of academic research in recent times, primarily owing to their ability to generate cost-effective and environmentally friendly sustainable energy on a commercial and industrial level. In this study, we propose the initiation of a research attempt focused on polymer solar cells that employ PBDB-T/ITIC as the active material. To facilitate this investigation, we have employed SCAPS-1D, a robust simulation program widely recognized for its effectiveness in the field. The objective of this study is to enhance the efficiency of a polymer solar cell composed of PBDB-T/ITIC as the absorber, P3HT as the Hole Transport Layer (HTL), and WS2 as the Electron Transport Layer (ETL) through the utilization of SCAPS simulation techniques. By systematically manipulating various parameters within the SCAPS device simulator, we have successfully incorporated the impact of temperature, thickness, defect density, and metal contacts on key performance parameters such as Open Circuit Voltage (Voc), Short Circuit Current density (Jsc), Fill Factor (FF), and Power Conversion Efficiency (PCE). We have developed a novel polymer-based solar cell utilizing the PBDB-T/ITIC material, which exhibits enhanced efficiency, improved temperature stability, and reduced environmental impact. The findings of our study may have the potential to assist the thin-film photovoltaic industry in the development of economically feasible and highly efficient polymer based solar cells.
