“…Considering the drawbacks of NiO, alternative p-type semiconductors with better optical transparency, lower VB edge position and higher hole mobility are desired for p-DSSCs. Several materials have been investigated as photocathodes in p-DSSCs, including CuO, 21 CuSCN, [22][23] GaP, 24 boron-doped diamond 25 and the Cu(I)-based delafossite compounds, CuMO 2 (M = Al, Ga or Cr). [26][27][28][29][30][31][32] Among them, the CuMO 2 series materials have shown very promising performances in p-DSSCs because of their intrinsic advantages over NiO.…”

The research of p-type dye-sensitized solar cells (p-DSSCs) has attracted growing attention because of the potential for integration with conventional n-type DSSCs (n-DSSCs) into the more efficient tandem-DSSCs. However, to date the performance of p-DSSCs is lagging behind that of n-DSSCs. One main reason is the lack of optimal photocathode materials. This article reviews the most recent progress in utilizing Cu(I)-based delafossite compounds, CuMO2 (M = Al, Ga or Cr), as photocathodes in p-DSSCs. As alternative materials to the commonly used NiO, the CuMO2 compounds have their intrinsic advantages such as lower valence band edge, larger optical bandgap and higher conductivity. By providing an insight into these materials and their applications in p-DSSCs, this perspective aims to stimulate more exciting research in the development of p-DSSCs as well as of tandem-DSSCs.

“…The schematic diagram in figure 2 is an example of a low-cost, near infra-red (NIR) photon detector [36]; the p-n heterojunction contains p-CuSCN and n-TiO 2 , deposited onto a glass substrate with a conductive-tin-oxide (CTO) Adapted and reprinted from [39] [41,42], where the device selectivity can be modulated by controlling the length of ZnO-nanorods [42]. Other dye-sensitized systems containing CuSCN are found in photoelectrochemical cells [43][44][45][46][47], with CuSCN-based dye-sensitized heterojunctions for photovoltaic cells soon proposed and realized by O'Regan and Schwartz [48][49][50].…”

Recent advances in large-area optoelectronics research have demonstrated the tremendous potential of copper(I) thiocyanate (CuSCN) as a universal hole-transport interlayer material for numerous applications, including, transparent thin-film transistors, high-efficiency organic and hybrid organicinorganic photovoltaic cells, and organic light-emitting diodes (OLEDs). CuSCN combines intrinsic hole-transport (p-type) characteristics with a large bandgap (>3.5 eV) which facilitates optical transparency across the visible to near infrared part of the electromagnetic spectrum. Furthermore, CuSCN is readily available from commercial sources while it is inexpensive and can be processed at low-temperatures using solution-based techniques. This unique combination of desirable characteristics makes CuSCN a promising material for application in emerging large-area optoelectronics. In this review article, we outline some important properties of CuSCN and examine its use in the fabrication of potentially low-cost optoelectronic devices. The merits of using CuSCN in numerous emerging applications as an alternative to conventional hole-transport materials are also discussed.

Third generation photovoltaics are based on the concept of providing high conversion efficiencies with low device production costs. As such, second generation concepts, such as Dye-sensitized Solar Cells (DSCs), serve as a good starting point for the development of these new devices. Tandem DSC devices are one example of such a concept, and can be constructed using two photoactive electrodes (one photoanode and one photocathode) inside the one cavity, increasing the theoretical efficiency limit by around 50% as compared to the conventional design. As there has been substantial effort devoted to the development of ntype DSCs, the focus of researchers investigating tandem DSCs has been to create high performance p-type systems, which operate by an analogous, but inverted, mechanism to n-type DSCs.
