"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 CH3NH3PbI3 perovskite \r\nphotovoltaic (PV) cells, in which pre-crystallized NiO nanoparticles (NPs) without post-treatment are \r\nused to form a hole transport layer (HTL). X-ray diffraction and high-resolution transmission electron \r\nmicroscopy showed the crystallinity of the NPs, and atomic force microscopy and scanning electron \r\nmicroscopy confirmed the uniform surfaces of the resultant NiO thin film and the subsequent perovskite \r\nphotoactive layer. Compared to the conventional poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) HTL, the NiO HTL had excellent energy-level alignment with that of CH3NH3PbI3 \r\nand improved electron-blocking capability, as analyzed by photoelectron spectroscopy and diode \r\nmodeling, resulting in Voc ~0.13 V higher than conventional PEDOT:PSS-based devices. Consequently, a \r\npower conversion efficiency (PCE) of 15.4% with a high fill factor (FF, 0.74), short-circuit current density \r\n(Jsc, 20.2 mA·cm−2), and open circuit voltage (Voc, 1.04 V) having negligible hysteresis and superior air \r\nstability has been achieved."^^ .
