1 the rapid progress in both device efficiency 2 3 4 5 6 7 8 and stability 9.
Perovskite solar cell substrate.
Solution processing perovskite based photovoltaic cells have reached a power conversion efficiency pce of 20 ref.
Efficient ch 3 nh 3 pbi 3 pcbm perovskite solar cells based on lead acetate were demonstrated.
The power conversion efficiency of devices derived from pb ac 2 reaches 14 81.
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.
For all substrate temperatures meo 2pacz enables higher solar cell pces than ptaa.
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.
Perovskite materials such as methylammonium lead halides and all inorganic cesium lead halide are cheap to produce and simple to manufacture.
The perovskite film shows enhanced substrate coverage and prolonged photoluminescence lifetime.
