Description
Subudhi and Narasimhan A simulate a lead-free solar cell in 2026, tuning a tin perovskite design in software to find the layer stack that squeezes out the most power. Tin cells promise safer chemistry than lead rivals, which now top 26 percent efficiency, but tin oxidizes easily and grows defective crystals. Their design mixes a two-dimensional protective component into the three-dimensional absorber and swaps charge transport layers in the simulator.
Two transport materials, C60 on one side and copper oxide Cu2O on the other, aligned their energy levels best with the absorber for clean charge extraction in the modeling. After tuning absorber thickness, defect density, temperature, and contact metal, the virtual cell reached an open-circuit voltage of 0.93 volts and a current of 18.46 milliamps per square centimeter. Its fill factor hit 81.21 percent and peak efficiency 14.2 percent, numbers the authors offer as a build target for laboratory tin cells.
