Organic–inorganic hybrid perovskite solar cells (PSCs) have attracted great attention due to their fascinating optical and electrical properties. Furthermore, their cost-effective low-temperature solution-processability has led extensive researches on low-cost flexible PSCs. However, low-temperature solution processed perovskite thin films generally contain the vacancies and defects in their surface and grain-boundary, and those imperfections induce the trap-assisted nonradiative recombination losses, decreasing their device performances. In this work, we develop a symmetrically-functionalized oxadiazole derivative molecule that can simultaneously work as an efficient hole transport layer of perovskite solar cell and passivate the defects in the perovskite photoactive layer by forming Lewis-adducts.
