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 ([similar]413 nm film thickness) is compared to a planar device, where the latter produces higher Voc but lower Jsc, and consequently lower efficiency at all measured light intensities.
