Interface engineering of organic-inorganic halide perovskite solar cells (PSCs) plays a pivotal role in achieving high power conversion efficiency (PCE). In fact, the photoactive layer needs to work synergistically with other functional components cell, such as charge transporting/active buffer layers and electrodes. this context, graphene related two-dimensional materials (GRMs) are promising candidates tune "on demand" interface properties PSCs. work, we fully exploit potential GRMs by...
Small area hybrid organometal halide perovskite based solar cells reached performances comparable to the multicrystalline silicon wafer cells.
