Abstract

The good electrical and morphological characteristics of TiO₂ nanofibers and the high extinction coefficient of CH₃NH ₃PbI₃ 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.
