Description
Hong-Tao Li and colleagues present a 2026 computer study of a lead-free perovskite solar cell design. Perovskite cells soak up sunlight well, but the best ones use toxic lead, so this team modeled a germanium-based version flipped in structure. They tested choices for the layers that carry positive and negative charges out of the cell, plus layer thickness and defect levels.
Two layer materials, WS2 and SnO2, worked best in the model. With a tuned absorber about 900 nanometers thick and very low defect levels, the simulated cell reached about 23 percent efficiency. Nothing was built in a lab, yet the numbers give makers a clear recipe to try for safer, high-output solar cells.
