Fabrication and Characterization of Element-Doped Perovskite Solar Cells

Abstract

Perovskite solar cells were fabricated and characterized. X-ray diffraction anal. and transmission electron microscopy were used for investigation of the devices. The structure anal. by them showed structural transformation of the crystal structure of the perovskite, which indicated that a cubic-tetragonal crystal system depended on the annealing condition. The photovoltaic properties of the cells also depended on the structures. Metal doping and halogen doping to the perovskite and TiO2 were also investigated. The results showed an increase in the efficiencies of the devices, due to the structural change of the perovskite compd. layers. [on SciFinder(R)]
