A topping of perovskites to boost solar cell efficiencies

Conventional solar cells still have some room to improve, but not so much. Therefore, researchers are looking at tandem solutions, stacking two different types of solar cells on top of each other. Imec, partner in EnergyVille, recently obtained record efficiencies by adding perovskite solar cells on top of conventional silicon and CIGS technology. Manoj Jaysankar, PhD researcher at imec and EnergyVille, explains.
