Perovskite layers intended for use as light-absorbing materials were fabricated by annealing spin-coated PbI₂ thin films on FTO/compact-TiO₂/porous-TiO₂ in CH₃NH₃I vapor while assessing the effects of varying the annealing temperature. Solar cells fabricated using perovskite thin films grown at 140-150 °C over 4 h exhibited power conversion efficiency values above 4%. In this study, a solar cell fabricated using Pb-free organic-inorganic material will be also discussed.
