Changing the way solar cells are made - A simple, low cost, low energy processing of perovskite solar cells
Perovskite is made by taking two pre-cursor salts and adding an organic cation to form a perovskite formulation. It can be applied to a glass substrate by various deposition methods including ink-jet printing, slot-die coating and vapour deposition. For both glass and PV cell manufacturers, this means processing perovskite uses standard industrial equipment rather than customised equipment.
Our thin film perovskite cells are intrinsically low cost with very high material utilization and low embodied energy. They compare extremely favourably with crystalline silicon, today’s dominant PV technology, which uses many mechanical and high temperature processes and has a low material utilization.
