“…PCBM/Al or a carbon electrode is generally employed for electron collection. In a recent report, a layered mesoporous scaffold successively assembling both n-type TiO 2 and p-type NiO has been shown [116]. The device exhibited extended electron lifetime and improved hole extraction of the counter electrode, leading to a PCE of 11.4%.…”

“…Another method involves the introduction of interfacial layer between the perovskite and carbon layer. Wang and co-workers [72,83,84] reported the use of NiO as hole selective contact and achieved a PCE of over 15% with the mesoscopic TiO2/Al2O3/NiO/carbon quadruple-layer architecture (Fig. 9d).…”

Organic-inorganic hybrid halide perovskite materials have been a suitable active layer in solar cells due to the extraordinary photonic and electronic properties. Perovskite solar cells (PSCs), no matter conventional structure or inverted structure, contain several key interfaces, including electrode/electron transport materials (ETM) interface, ETM/perovskite interface, perovskite/hole transport materials (HTM) interface, HTM/electrode interface. The interface is vital to the overall performance of the devices, since the exciton formation, dissociation, and recombination are directly related to the interface. Moreover, the degradation of devices is also highly sensitive to the interface. As a result, the deep understanding of the interfacial charge transfer and corresponding interfacial engineering is extremely important to achieve high-performance and high-stability PSCs. This review mainly focuses on the recent progress of interfacial engineering in PSCs, including conventional structured PSCs, PSCs employing carbon counter electrode, and inverted structured PSCs.

“…Recently, significant improvements on NiO-based PSCs were made by doping the NiO thin film or modifying the NiO/perovskite interface heterojunction [98][99][100][101][102]. Kim et al demonstrated a high-efficiency planar PSC by using solution-processed copper (Cu)-doped NiO x (Cu:NiO x ) as a HTM [122].…”

“…The PSCs were composed of FTO/compact TiO 2 /mesoporous TiO 2 /mesoporous NiO/carbon, in which the light absorber CH 3 NH 3 PbI 3 was infiltrated inside the pores of mesoporous TiO 2 /mesoporous NiO/carbon via sequential deposition [101]. Application of mesoporous NiO as a HTM effectively suppresses charge recombination and facilitates hole extraction, resulting in a cell with a PCE of 11.4% [102]. Furthermore, the same groups applied highly-crystalline NiO nanosheets as top nanostructured charge transport layers and inserted an additional mesoporous ZrO 2 layer to achieve an n-i-p heterojunction.…”

Considering the increasing global demand for energy and the harmful ecological impact of conventional energy sources, it is obvious that development of clean and renewable energy is a necessity. Since the Sun is our only external energy source, harnessing its energy, which is clean, non-hazardous and infinite, satisfies the main objectives of all alternative energy strategies. With attractive features, i.e., good performance, low-cost potential, simple processibility, a wide range of applications from portable power generation to power-windows, photoelectrochemical solar cells like dye-sensitized solar cells (DSCs) represent one of the promising methods for future large-scale power production directly from sunlight. While the sensitization of n-type semiconductors (n-SC) has been intensively studied, the use of p-type semiconductor (p-SC), e.g., the sensitization of wide bandgap p-SC and hole transport materials with p-SC have also been attracting great attention. Recently, it has been proved that the p-type inorganic semiconductor as a charge selective material or a charge transport material in organometallic lead halide perovskite solar cells (PSCs) shows a significant impact on solar cell performance. Therefore the study of p-type semiconductors is important to rationally design efficient DSCs and PSCs. In this review, recent published works on p-type DSCs and PSCs incorporated with an inorganic p-type semiconductor and our perspectives on this topic are discussed.
