Flexible perovskite solar cell with 21.0% efficiency, high durability
International researchers have placed a low-dimensional metal-halide perovskite capping layer on top of a metal-halide perovskite film to provide hermetically sealed encapsulation and enhanced photocarrier properties. The cell has a short-circuit current density of 23.5 mA.cm2, an open-circuit voltage of 1.15 V, and a fill factor of 0.779.
