Title: Fabrication of high efficiency perovskite solar cells based on mesoporous TiO2 nanofibrous film under high humidity conditions

Abstract

Highlights: • 1D TiO{sub 2} nanofibrous film was prepared by electrospinning technique as mesoporous of PSCs. • PSCs were fabricated under ambient conditions even with a high humidity condition more than 40%. • The 1D TiO{sub 2} nanofiber-based PSCs achieved a power conversion efficiency (PCE) about 11.6% compared with 7.5% whereas the 0D TiO{sub 2} nanoparticle-based PSCs only has 7.5%. - Abstract: One-dimensional (1D) TiO{sub 2} nanofibrous film with good morphology and electrical characteristics was prepared by electrospinning technique. And then perovskite solar cells (PSCs) were fabricated based on 2-μm-thick mesoporous TiO{sub 2} nanofibrous film under ambient conditions even with a high humidity condition more than 40%. The devices show high power conversion efficiency (PCE) due to high porosity that is beneficial to the loading of CH{sub 3}NH{sub 3}PbI{sub 3} perovskite layer. This high-porosity 1D TiO{sub 2} nanofibrous film also acts as a protection layer which can enhance the moisture stability of CH{sub 3}NH{sub 3}PbI{sub 3}. As a result, conversion efficiency of 11.6% and short-circuit current density (J{sub sc}) of 17.3 mA were achieved under 100 mW cm{sup −2} AM 1.5 G solar illumination. These two values are both higher than those of zero-dimensional (0D) TiO{sub 2} nanoparticulate film-based devices.
