Perovskite solar cell substrate.

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. The perovskite film shows enhanced substrate coverage and prolonged photoluminescence lifetime. Perovskite materials such as methylammonium lead halides and all inorganic cesium lead halide are cheap to produce and simple to manufacture.

As such our existing substrate infrastructure and perovskite materials are already being used in high performance solution processed perovskite devices. The power conversion efficiency of devices derived from pb ac 2 reaches 14 81. 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.
