Fabricating inorganic-organic hybrid perovskite solar cells (PSCs) on plastic substrates broadens their scope for implementation in real systems by imparting portability, conformability and allowing high-throughput production, which is necessary for lowering costs. Here we report a new route to prepare highly dispersed Zn2SnO4 (ZSO) nanoparticles at low-temperature (<100 ℃) for the development of high-performance flexible pscs. the introduction of the zso film significantly improves transmittance of flexible polyethylene naphthalate/indium-doped tin oxide (pen/ito)-coated substrate from ~75 to ~90% over the entire range of wavelengths. the best performing flexible psc, based on the zso and ch3nh3pbi3 layer, exhibits steady-state power conversion efficiency (pce) of 14.85% under am 1.5g 100 mw·cm-2 illumination. this renders zso a promising candidate as electron-conducting electrode for the highly efficient flexible psc applications.
