Perovskite Solar Cell Substrate

The perovskite film shows enhanced substrate coverage and prolonged photoluminescence lifetime.

Perovskite solar cell substrate.

Perovskite materials such as methylammonium lead halides and all inorganic cesium lead halide are cheap to produce and simple to manufacture. The power conversion efficiency of devices derived from pb ac 2 reaches 14 81. For all substrate temperatures meo 2pacz enables higher solar cell pces than ptaa. Efficient ch 3 nh 3 pbi 3 pcbm perovskite solar cells based on lead acetate were demonstrated.

As such our existing substrate infrastructure and perovskite materials are already being used in high performance solution processed perovskite devices. 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. 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. Solution processing perovskite based photovoltaic cells have reached a power conversion efficiency pce of 20 ref.
