High conversion efficiency and stability are above all important topics in the current study of perovskite solar cells (PSCs), which determine the future of their commercialization. According to the intrinsic characters of PSCs, interface engineering plays a key role in enhancing both conversion efficiency and stability of PSCs. In this work, we developed a robust interface engineering for "inverted" planar heterojunction PSCs of low temperature and faCELe solution processed PEOz nanodots film. The PEOz nanodots film acts as electron extraction layer and NiOx nanostructured film acts as a hole transport layer in a configuration of ITO/NiOx /Perovskite/PCBM/PEOz/Ag. Such design results in an open circuit voltage (V-oc) of 1.07 V, a short-circuit current (J(sc)) of 21.93 mA/cm(2), and a fill factor (FF) of 77.9%, corresponding to a maximum PCE of 18.28%, in contrast to a conversion efficiency of 11.98% for the same structure devices without PEOz cathode electron-extraction layer. Moreover, the combination of the two layers leads to highly stable planar PSCs and hence high durability. A series of experiments and characterizations were performed and collected to support the discovery. Our results provide a scientific basis for the scale-up production of future PSCs.
