Perovskite Solar Cell Substrate

1 the rapid progress in both device efficiency 2 3 4 5 6 7 8 and stability 9.

Perovskite solar cell substrate.

Efficient ch 3 nh 3 pbi 3 pcbm perovskite solar cells based on lead acetate were demonstrated. For all substrate temperatures meo 2pacz enables higher solar cell pces than ptaa. The power conversion efficiency of devices derived from pb ac 2 reaches 14 81. 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. 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. 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.
