Current progress and scientific challenges in the advancement of organic–inorganic lead halide perovskite solar cells

摘要: The solution-processed organic–inorganic lead halide perovskite solar cells have recently emerged as promising candidates for the conversion of power into electricity. certified efficiencies these rapidly increased from 3.8% in 2009 to 22.1% 2016. Although experimentally observed value efficiency date is up 22.1%, some main issues such stability, toxicity, and hysteretic behavior I–V characteristics addition high been creating problems regarding their industrial applications. Theoretical results demonstrated that perovskites exhibit a series superior electronic optical properties cell applications, proper band alignment, controlled doping ability, lattice point defects, ferroelectric properties, dynamic disorder, domain walls, local structural properties. In this review, important required produce highly efficient are discussed based on experimental theoretical studies. We also present key scientific challenges future research directions development field commercialization.
