Developed through bandgap engineering and material design, the proposed PV device relies on a tin-based perovskite
PV Magazine International 11:17 am on May 14, 2024
Indian scientists have designed a lead-free, perovskite solar cell with 23.61% efficiency through bandgap engineering and material design. The cell utilizes a tin-based perovskite material (CsSnI3-xBrx), featuring linear and parabolic bandgaping grading techniques for optimal light absorption and performance enhancement, potentially exceeding 24%.
- Bandgap Engineering: Bandgap grading using linear and parabolic methods significantly boosts solar cell efficiency.
- Material Selection: The perovskite material used is a tin-based compound with lead substituted, enhancing environmental sustainability.
- High Efficiency: Simulations suggest that the designed solar cell configuration could reach up to 24% power conversion efficiency.
- Research Publication: The study was published in Solar Energy, offering a viable path towards commercially scalable lead-free perovskite photovoltaic technologies.
- Sustainability Focus: This innovation aligns with global efforts to reduce the environmental impact of solar technology through material sustainability.
