Direct observation of photoinduced carrier blocking in mixed-dimensional 2D/3D perovskites and the origin
Abstract
Mixed dimensional 2D/3D halide perovskite solar cells practically deliver poorer efficiency, and the 2D fragments have been considered responsible. Here, the authors unveil a photoinduced carrier blocking effect at the 2D/3D perovskite interface that could truly jeopardize device parameters.
