Abstract
The efficiency of charge transport at interfaces and bulk affects the performance for lots optoelectronic devices. In this work, vacancies in nano-mesoporous TiO2 have been modified by hydrogen peroxide and the corresponding photoactive electrode for halide perovskite solar cells shows remarkable improvement of current density (Jsc) 36% and open circuit voltage (Voc) 10%, with overall improvement of efficiency over 75%. Photovoltage decay indicates the electron lifetime have been almost doubled after hydrogen peroxide treatment.
