To fully harness the potential of sunlight, scientists have been trying to maximize the amount of energy that can be extracted from the sun. Researchers now describe how pairing metal halide perovskites with conventional silicon leads to a more powerful solar cell that overcomes the 26% practical efficiency limit of using silicon cells alone. Perovskites fulfill all the optoelectronic requirements for a photovoltaic cell, and they can be manufactured using existing processes.
