Fabrication and Characterization of Perovskite Solar Cells added with MnCl2, YCl3 or Poly(methyl methacrylate)

Perovskite-type CH(3)NH(3)Pbb-based photovoltaic devices were fabricated and characterized. Effects of manganese (Mn), yttrium (Y) compounds addition into the perovskite crystal on the photovoltaic properties were investigated. Also, the effects of poly(methyl methacrylate) (PMMA) addition on perovskite layer on the photovoltaic properties were investigated. When 3 % MnCl2 was added, the short circuit current density and conversion efficiency were improved by promoting the crystal growth of perovskite phase. The photoelectric conversion efficiency for 0.9 mg mL(-1) PMMA added was 7.36 %. Open circuit voltage and till factor were improved by 5 % YCl3 addition.
