Recently, hybrid lead halide perovskite photovoltaics have shown an unprecedented evolution from their original publication, reaching efficiencies which are comparable to c-Si in just a few years. This family of materials is easily processable from solution and shows properties comparable to GaAs, making them highly attractive for commercial photovoltaics.
At the optoelectronics group we specialize on understanding the fundamental mechanisms which govern these materials, and find a link to connect the fundamental properties with an application in making devices. These include LEDs, Lasers, Transistors and Solar Cells.
Our main focus at the moment is on combining perovskite with other active materials to form tandem structures, such as singlet fission chromophores and inorganics such as silicon.
