Tandem Perovskite-Silicon Solar Breaks Record, Efficiency
The first method is to deposit a perovskite layer in a liquid on a smooth silicon solar energy unit, creating efficiency up to 30.93% in a 1 square centimeter solar energy battery. The second uses a hybrid vapor and liquid solution technique to deposit perovskites onto textured silicon surfaces, yielding 31.25 percent efficiency for a 1-square-centimeter solar cell.
