Abstract:
In recent years, organic-inorganic hybrid lead-halide perovskite solar cells have got rapid progress and exhibited high photoelectric conversion efficiencies （PCE） of up to 20%. A perovskite solar cell is a type of solar cell which includes a perovskite structured compound, most commonly an organic-inorganic hybrid lead or tin halide-based material, as the light-harvesting active layer. Perovskite materials such as the methylammonium or formamidinium lead halides are cheap to produce and simple to manufacture. Their high efficiencies and low production costs make perovskite solar cells a commercially attractive option. In this paper, the research status and latest development of perovskite solar cells are reviewed including their structures and performances, especially for Pbfree perovskite solar cells. Finally, the key technologies and core scientific problems that are needed to solve for practical application of perovskite solar cells are also elaborated.
