“…To this end, recent effort has been focused in developing solution-processing methods to enable the deposition of semiconducting films at low cost and onto large substrates. [7] In this respect, CuSCN can be solution-processed, [11][12][13] and its applications in various opto/electronic devices grown from solution have been demonstrated. [1, 3-5, 8, 14-19] Despite the tremendous promise, however, basic understanding of the electronic properties of CuSCN is still lacking.…”

“…Solid-hole transport materials and solvent free polymer electrolyte incorporating iodide and triiodide have been introduced to replace the liquid electrolytes, but until now efficiencies of these devices are still relatively low [8][9][10][11][12][13][14]. The use of non-volatile liquids or room temperature molten salts (ionic liquids) such as imidazolium salts and pyridinium salts with high ionic conductivity at room temperature would be another solution to the problems.…”

There have been many attempts to increase the overall conversion efficiency of dye-sensitized solar cells using liquid-state electrolytes. However, this type of cells have unsolved critical problems such as leakage and evaporation of volatile organic solvents. Thus the development of more stable solid or quasi-solid state cell is of great importance. In the study reported here, we developed a novel fabrication method of dye sensitized quasi-solid solar cells using solid composite materials of LiSCN and methyl-hexyl-imidazolium iodide (MHImI) as hole transport materials to replace liquid iodide and polyiodide electrolyte which consists of volatile solvents. The device based on 6 µm thick nanocrystalline TiO 2 film absorbed by monolayer of Ru(II) terpyridyl complex photosensitizer (N719 dye), shows excellent incident photon-to-electron conversion efficiency (IPCE, ~ 75%) , large current density (11.6 mA cm -2 ), and high light-to-electric energy conversion efficiency (5.3-6.1%) under the illumination of 100 mW cm -2 (AM 1.5).

“…Apparently improved photocurrent was demonstrated by Kumara et al wherein CuSCN dissolved in n-propyl sulfide was deposited on Ru-dye coated TiO 2 film, showing PCE of 1.25% and J sc of 3.52 mA/cm 2 [46]. In 2002, O'Regan et al reported a further improved SSDSC by pore filling control, performing an efficiency of 2.1% with a higher photocurrent of~8 mA/cm 2 [47].…”

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.
