“…The maximum open-circuit voltage (V oc ) for a photocathode is the difference between the quasi-Fermi level above the valence band (E V ) and the redox potential of the electrolyte [30]. The change in V oc has been attributed either to an E V shift or to the reduced recombination at the NiO/electrolyte interfaces [31].…”

The present work reports a simple Ni(CH 3 COO) 2 post-treatment method, meanwhile represents a series of characterizations of bare and post-treated NiO photocathodes. The investigation enlightens the mechanisms responsible for NiO surface changes and its effects on the charge density, band-edge shifts, hole injection efficiency, interface recombination, transport, collection efficiency, and as the result influence on the photovoltaic devices' performance. The primary results demonstrate that Ni(CH 3 COO) 2 post-treatment can offer an effective way of decreasing surface NiO(OH) structure, resulting in diminishing the hole recombination, increasing the charge collection efficiency, and leading to 31.3 % increased photovoltaic performance.

“…The first step in realizing transparent semiconductor devices is obtaining p-type conducting films and fabricating a visible light-transparent pn-junction by a simple, conventional, and economical deposition technique. In fact, NiO has attracted attention because Li-, 4,5 K-, 6 Cu-, 7 or unintentionally doped NiO shows p-type conductivity. [8][9][10][11] Therefore, transparent diodes, [12][13][14][15][16] ultraviolet (UV)-visible light emitting diodes, 17 and UV detectors 18 have been fabricated by using p-type NiO and n-type oxide semiconductors (e.g., ZnO) because indirect and direct bandgap energies of NiO are approximately 3.7 eV.…”

The energy band diagrams of NiO-based solar cell structures that use various n-type oxide semiconductors such as ZnO, Mg 0.3 Zn 0.7 O, Zn 0.5 Sn 0.5 O, In 2 O 3 :Sn (ITO), SnO 2 , and TiO 2 were evaluated by photoelectron yield spectroscopy. The valence band discontinuities were estimated to be 1.6 eV for ZnO/NiO and Mg 0.3 Zn 0.7 O/NiO, 1.7 eV for Zn 0.5 Sn 0.5 O/NiO and ITO/NiO, and 1.8 eV for SnO 2 /NiO and TiO 2 /NiO heterojunctions. By using the valence band discontinuity values and corresponding energy bandgaps of the layers, energy band diagrams were developed. Judging from the band diagram, an appropriate solar cell consisting of p-type NiO and n-type ZnO layers was deposited on ITO, and a slight but noticeable photovoltaic effect was obtained with an open circuit voltage (V oc ) of 0.96 V, short circuit current density (J sc ) of 2.2 lA/cm 2 , and fill factor of 0.44.

“…Among these available ptype materials, nickel oxide (NiO) has been highlighted for its intrinsic p-type conductivity and transparent oxide semiconductor nature [25]. Although NiO has been widely employed in various applications such as electrochromic devices [26], transparent conduction films [27], and chemical sensors [28][29][30], it has not been examined to improve the piezoelectric performance of ZnO-based nanogenerators, to the best of our knowledge.…”
