A concept developed at the National Renewable Energy Laboratory (NREL) may simplify the process to manufacture perovskite solar cells, possibly accelerating the path toward the technology’s commercialization.
Perovskite solar cells are made by depositing various layers onto a conductive glass substrate. Multiple coatings are needed to create the full device structure. The technique from NREL combines or eliminates altogether some of the steps, simplifying the manufacturing process and potentially lowering manufacturing costs.
Perovskite is a calcium titanium oxide mineral composed of calcium titanate. Its name is also applied to the class of compounds which have the same type of crystal structure as CaTiO₃, known as the perovskite structure.
Perovskite solar cells are composed of a perovskite light-absorbing layer a
