“…The slightly smaller V oc is probably caused by the negative shift of the formal potential for the polysulfide redox couple in contact with CuSe, as the V oc is mainly determined by the Fermi level of the photoelectrode and the redox potential of the electrolyte. 38,39 Similar phenomena have been reported elsewhere. [40][41][42] The J sc values exhibit a slight increase from 17.20 to 18.88 mA cm −2 , when replacing Cu 2 S with CuSe CEs.…”

We report a novel method to prepare efficient CuSe counter electrodes for quantum dot sensitized solar cells. The CuSe films are deposited on fluorine doped tin oxide substrates using a two-step solution-based method. The unique morphology and excellent catalytic property of the CuSe films are characterized thoroughly. Employing this novel counter electrode, the CdSe quantum dot sensitized solar cells exhibit the best power conversion efficiency of 5.77%, outperforming the reference devices applying Cu 2 S counter electrodes. The preparation method is transferable to fabricate other metal selenide functional electrodes, promising a broader application in solar cells.

“…In solar cell application, metal oxides such as SnO 2 [95], ZnO [114], and SrTiO 3 [115] are often used as photoelectrodes in dye solar cells (DSCs) [116,117]. DSCs are made by a layer of dye-anchored mesoporous metal oxides, known as photoelectrodes, and covered with conducting glass plates on both sides [118].…”

Metal oxides are widely used in many applications such as thermoelectric, solar cells, sensors, transistors, and optoelectronic devices due to their outstanding mechanical, chemical, electrical, and optical properties. For instance, their high Seebeck coefficient, high thermal stability, and earth abundancy make them suitable for thermoelectric power generation, particularly at a high-temperature regime. In this article, we review the recent advances of developing high electrical properties of metal oxides and their applications in thermoelectric, solar cells, sensors, and other optoelectronic devices. The materials examined include both narrow-band-gap (e.g., Na x CoO 2 , Ca 3 Co 4 O 9 , BiCuSeO, CaMnO 3 , SrTiO 3 ) and wide-band-gap materials (e.g., ZnO-based, SnO 2 -based, In 2 O 3 -based). Unlike previous review articles, the focus of this study is on identifying an effective doping mechanism of different metal oxides to reach a high power factor. Effective dopants and doping strategies to achieve high carrier concentration and high electrical conductivities are highlighted in this review to enable the advanced applications of metal oxides in thermoelectric power generation and beyond.

“…Transparent or semitransparent electrodes can be used for building-integrated photovoltaics (BIPVs) to make use of light from the interior of the building as well as the outside. [879][880][881] So far, efficient solutionprocessed transparent CEs have been reported using both PEDOT and binary-alloy transition metal chalcogenides (M-Se; M = Ni, Co, Fe, Cu, and Ru). For example, bifacial DSSCs with CEs composed by a metal selenide achieved front Z values of 8.3%, 7.8%, 6.4%, 7.6%, and 9.2% for Co 0.85 Se, Ni 0.85 Se, Cu 0.50 Se, FeSe, and Ru 0.33 Se, respectively, which were even higher than that of a cell with an electrode based on standard Pt (6.1%).…”

“…In addition, it should be noted that 2D materials have been used to develop efficient, transparent CEs for bifacial DSSCs, which emerged as interesting systems for both BIPVs and tandem SCs. [878][879][880]889 The most successful applications of GRMs in PV technologies rely on their use in the form of CTLs for both holes and electrons (or interlayers in tandem PV architectures). For example, GRMs effectively act as dopants to improve the properties of traditional CTLs.…”
