Enhancing Photovoltaic Performance of CsPbI2Br-Based Perovskite Solar Cells through Thickness Optimization

In this investigation, the potential for perovskite solar cells (PSCs) based on CsPbI
2
Br to be a promising source of renewable energy is examined. The study investigates the impact of the thickness of the CsPbI2Br layer that is active on the total effectiveness of the PV cells. PSC benefit from the CsPbI
2
Br material because it balances their effectiveness with thermal and chemical stability. The ideal PV values are J
SC
: 18.65mA/cm

: 1.35V. The investigation's culmination shows that the ideal PCE of 20.21% is achieved with a 1000 nm CsPbI
2
Br active layer, highlighting the material's potential as a highly effective and promising choice for sustainable energy conversion. Increased PV performance results from the device's efficiency being increased with a thickness of CsPbI
