Synthesis and analysis of bi halide double perovskite material towards lead free photo voltaic cells

Abstract

The core objective of this research is a comprehensive investigation into the interplay and performance dynamics of Cs2TiBr6 when coupled with various inorganic charge transport materials. To achieve this, the researchers employ the SCAPS-1D simulation software, a Solar Cell Capacitance Simulator known for its adeptness in modelling solar cell devices. The simulated environment allows for the manipulation of critical parameters such as interface defect density, thickness, and defect density across diverse layer materials. This systematic exploration aims to unravel the intricacies of how these variations impact the overall functionality of the solar cell device. The simulation process involves the meticulous incorporation of a spectrum of fundamental input parameters. These encompass electron affinity, thickness, bandgap, charge mobility, permittivity, and defect density, among others, for different layer materials. The richness of this input data allows for the creation of a sophisticated and nuanced model, mirroring the intricacies of the novel solar cell structure under investigation. At its essence, this numerical research strives to usher in a new era of highly efficient and environmentally friendly perovskite solar cell structures. The analysis results are subjected to rigorous comparison with existing data, providing a robust foundation for the substantiation of the research findings. The goal is not merely to understand the theoretical underpinnings but to pave the way for tangible advancements in solar cell technologies. newline
