Perovskite Tandem Solar Cells | Ossila
Perovskite tandem solar cells are a type of tandem solar cell, which uses perovskite materials as one, or both, of the active layers. The bandgap of a perovskite can be easily tuned by changing the perovskite composition, meaning that it can be paired with other solar cells, such as silicon, CIGS, or organic photovoltaics, to make hybrid tandem
