Tandem Energy

Combining two (or more) carefully selected solar cells with unique material properties in a tandem configuration, allows us to convert a larger portion of the light spectrum into electrical energy. This approach enables us to surpass the physical limitations of individual solar cells. For example, combining a perovskite upper cell with a silicon cell.

At EnergyVille, our aim is to achieve a tandem energy conversion efficiency of over 30%, surpassing the theoretical maximum of approximately 28% for silicon solar cells. Our research explores various material combinations, processes, and contact configurations (2-terminal, 4-terminal tandems) to develop stable and reliable tandem configurations on a large scale, for instance, in the M2 format and up to 30×30 cm.
