Perovskite Solar Cell Substrate

As such our existing substrate infrastructure and perovskite materials are already being used in high performance solution processed perovskite devices.

Perovskite solar cell substrate.

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. 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. 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. Perovskite materials such as methylammonium lead halides and all inorganic cesium lead halide are cheap to produce and simple to manufacture.

Solution processing perovskite based photovoltaic cells have reached a power conversion efficiency pce of 20 ref. The power conversion efficiency of devices derived from pb ac 2 reaches 14 81. The perovskite film shows enhanced substrate coverage and prolonged photoluminescence lifetime. For all substrate temperatures meo 2pacz enables higher solar cell pces than ptaa.
