Escalating the performance of perovskite solar cell via electrospun TiO2 nanofibers

摘要

A Perovskite solar cell is a type of solar cell which includes a perovskite structured compound, most commonly a hybrid organic-inorganic lead or tin halide based material, as the light harvesting active layer. In this work solar cell based on titanium dioxide (TiO2) thin film, sensitized with methyl ammonium lead iodide (CH3NH3PbI3) perovskite are prepared. Thin films were grown on fluorine doped tin oxide (FTO) glass plate. TiO2 is working as the anode and a noble metal will work as the cathode. A perovskite is more efficient than a dye in sensitizing a solar cell. It will act both as hole transporting material and sensitizer. It is found that the efficiency of solar cell devices using these materials shows considerable change in Voc and Jsc by the use of TiO2 nanofibers as the anode material.
