Perovskite Solar Cell Substrate

Through the combination of vapor deposited perovskites and a self assembled monolayer we achieve a stabilized power conversion efficiency of 20 6 which is the first reported pce above 20 for evaporated perovskite solar cells in p i n architecture.

1 the rapid progress in both device efficiency 2 3 4 5 6 7 8 and stability 9. The perovskite film shows enhanced substrate coverage and prolonged photoluminescence lifetime. The power conversion efficiency of devices derived from pb ac 2 reaches 14 81. Efficient ch 3 nh 3 pbi 3 pcbm perovskite solar cells based on lead acetate were demonstrated.

Solution processing perovskite based photovoltaic cells have reached a power conversion efficiency pce of 20 ref. This solution is applied and optimized for perovskite solar cells pscs with distinct thicknesses of the perovskite absorber the conventional 500 nm and ultra thin 300 nm in view of enhanced flexibility yielding photocurrent improvements up to 22 8 in superstrate cell configuration and 24 4 in substrate type configuration. A perovskite solar cell psc is a type of solar cell which includes a perovskite structured compound most commonly a hybrid organic inorganic lead or tin halide based material as the light harvesting active layer. As such our existing substrate infrastructure and perovskite materials are already being used in high performance solution processed perovskite devices.
