摘要

Recently, lead-based perovskite solar cells (PSCs) grabbed the worldwide popularity in photovoltaic industry owing to its remarkable properties. Few challenges such as toxic elements, instability, low shelf life etc. restricts the use of inorganic–organic lead based PSCs. To overcome these issues, eco-friendly, lead-free and stable cesium titanium (Cs2TiBr6) single-halide based absorber material have been introduced. In this work, FTO/SnO2/ Cs2TiBr6/MoOx/Au structure has been simulated by SCAPS-1D. The factors such as light absorbing layer thickness including charge transport layer thickness, doping, defect density, operating temperature, quantum efficiency etc. have thoroughly been examined in relation to different characteristics of PSCs. After calculation of all these parameters then a comparison is made between the proposed (Cs2TiBr6) structure with the previously reported experimental and simulation based Cs2TiBr6 perovskite structures. As a result, maximum power conversion efficiency (PCE) reached upto 20.11% along a FF = 82.17, Voc = 1.488 V, and Jsc = 16.34 mA/cm2. Hence, this work motivates the researchers to fabricate the highly efficient, low-toxic and stable PSCs in future for solar cell industry.
