Harvesting the power of the Sun is one of the most promising strategies to supply the world with sustainable, clean, and low-cost energy. The most viable approach to reach efficiencies well beyond those of today's commercial solar cell technologies is to form a tandem device by combining a narrow-bandgap bottom cell with a top cell exhibiting a wider bandgap, thereby reducing thermalization losses. This communhication reviews the on-going research in ENEA on the development of innovative tandem solar cells realized with a silicon heterojunction bottom cell and a perovskite or kesterite top cell.
