High efficiency electrospun TiO2nanofiber based hybrid organic–inorganic perovskite solar cell

Year: 2013

Type: article

Abstract: The good electrical and morphological characteristics of TiO₂ nanofibers and the high extinction coefficient of CH₃NH₃PbI₃ perovskite are combined to obtain a solar cell with a power conversion efficiency of 9.8%. The increase of the film thickness dramatically diminishes the performance due to the reduction in porosity of the TiO₂ nanofiber framework. The optimum device (∼413 nm film thickness) is compared to a planar device, where the latter produces higher V(oc) but lower J(sc), and consequently lower efficiency at all measured light intensities.
