Solution-Processible Crystalline NiO Nanoparticles for High-Performance Planar Perovskite Photovoltaic Cells

In this work, we report on solution-based p-i-n-type planar-structured CH(3)NH(3)PbI(3) perovskite photovoltaic (PV) cells, in which precrystallized NiO nanoparticles (NPs) without post-treatment are used to form a hole transport layer (HTL). X-ray diffraction and high-resolution transmission electr...

description In this work, we report on solution-based p-i-n-type planar-structured CH(3)NH(3)PbI(3) perovskite photovoltaic (PV) cells, in which precrystallized NiO nanoparticles (NPs) without post-treatment are used to form a hole transport layer (HTL). X-ray diffraction and high-resolution transmission electron microscopy showed the crystallinity of the NPs, and atomic force microscopy and scanning electron microscopy confirmed the uniform surfaces of the resultant NiO thin film and the subsequent perovskite photoactive layer. Compared to the conventional poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) HTL, the NiO HTL had excellent energy-level alignment with that of CH(3)NH(3)PbI(3) and improved electron-blocking capability, as analyzed by photoelectron spectroscopy and diode modeling, resulting in V(oc) ~0.13 V higher than conventional PEDOT:PSS-based devices. Consequently, a power conversion efficiency (PCE) of 15.4% with a high fill factor (FF, 0.74), short-circuit current density (J(sc), 20.2 mA·cm(−2)), and open circuit voltage (V(oc), 1.04 V) having negligible hysteresis and superior air stability has been achieved.
