Perovskite solar cell substrate.

As such our existing substrate infrastructure and perovskite materials are already being used in high performance solution processed perovskite devices. The perovskite film shows enhanced substrate coverage and prolonged photoluminescence lifetime. Solution processing perovskite based photovoltaic cells have reached a power conversion efficiency pce of 20 ref. At the most basic level most perovskite based solar cells are based upon a transparent conductive oxide coated glass substrate with evaporated metal cathode and top encapsulation.

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. Efficient ch 3 nh 3 pbi 3 pcbm perovskite solar cells based on lead acetate were demonstrated. 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. 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.
