摘要
Organic-inorganic perovskite materials are very suitable for flexible devices because high quality perovskite films can be deposited through a low temperature solution process.However, the power conversion efficiency(PCE) of flexible perovskite solar cells is still much lower than that of rigid devices partially due to the poor carrier transport properties of contact films employed in flexible devices.In this presentation, we will introduce several methods to prepare high quality NiO_x hole transport films for perovskite solar cells, and the focus will be put on some low temperature derived NiO_x films which is very suitable for flexible devices.Particularly, we demonstrated a solution-derived NiO_x-based inverted planar heterojunction perovskite solar cell with a PCE of as high as 16.47% on an ITO-glass substrate.The NiO_x film was deposited at a temperature of 130 ℃ without any post treatment.Detailed study on the interfacial carriers transfer and charge recombination processes proved it to be an efficient hole contact for perovskite film.Particularly, the low temperature deposition process made it very suitable and attractive for flexible devices.A preliminary PCE of 13.43% was demonstrated with NiO_x-based flexible perovskite solar cell using an ITO-PEN(polyethylene naphthalate) substrate.Besides, a solvothermal method was also employed to prepare ultrafine crystalline NiO_x nanoparticles, which can be well dispersed in ethanol and stable for weeks.High quality NiO_x films were able to be deposited onto flexible substrates from such kind of NiO_x colloids, based on which efficient flexible perovskite solar cells can also be achieved.
