“…Recently CuSCN has been proven to be a promising alternative to NiO as a p-type material scaffold in liquid-junction QDSCs. 194 In this report, CuSCN nanowires were used as photocathode in the construction of p-QDSSCs, and efficient sensitization by CuInSxSe2-x QDs was observed.…”

“…Photophysical charge transfer measurement results indicated that hole extraction rates in p-type QDSCs are in the same range as electron injection rates in conventional n-type QDSCs. [193][194][195] Moreover, the most promising application of p-type sensitized solar cells is the construction of a tandem configuration with the combination of a p-type and an n-type one to overcome the Shockley-Queisser limit. 196 Even though the concept of p-type QDSCs is very appealing, the efficiencies for most of them are very low or not reported, [197][198][199] with one exception of 1.25% reported by Aldakov and coworkers in 2016.…”

Quantum dot-sensitized solar cells (QDSCs) have emerged as a promising candidate for next-generation solar cells due to the distinct optoelectronic features of quantum dot (QD) light-harvesting materials, such as high light, thermal, and moisture stability, facilely tunable absorption range, high absorption coefficient, multiple exciton generation possibility, and solution processability as well as their facile fabrication and low-cost availability. In recent years, we have witnessed a dramatic boost in the power conversion efficiency (PCE) of QDSCs from 5% to nearly 13%, which is comparable to other kinds of emerging solar cells. Both the exploration of new QD light-harvesting materials and interface engineering have contributed to this fantastically fast improvement. The outstanding development trend of QDSCs indicates their great potential as a promising candidate for next-generation photovoltaic cells. In this review article, we present a comprehensive overview of the development of QDSCs, including: (1) the fundamental principles, (2) a history of the brief evolution of QDSCs, (3) the key materials in QDSCs, (4) recombination control, and (5) stability issues. Finally, some directions that can further promote the development of QDSCs in the future are proposed to help readers grasp the challenges and opportunities for obtaining high-efficiency QDSCs.

“…In particular, the formation of a dense ligand double layer consisting of dodecanethiolate and in situ formed didodecylsulfide has been identified. Due to the high chemical stability and interesting electronic and optical properties of these nanomaterials, they have been successfully used in a variety of applications: for biolabeling, , hybrid and sensitized − solar cells, photodetectors, and more recently photocatalytic hydrogen production . At present, a multitude of potential applications of CuInS 2 NCs exist, and first examples of their commercialization appear, making this type of nanocrystal one of the frontrunners among safer-by-design CSQDs.…”

Despite the young age of the research field, substantial progress has been made in the study of metal halide perovskite nanocrystals (HPNCs). Just as their thin-film counterparts are used for light absorption in solar cells, they are on the way to revolutionizing research on novel chromophores for light emission applications. Exciting physics arising from their peculiar structural, electronic, and excitonic properties are being discovered with breathtaking speed. Many things we have learned from the study of conventional semiconductor quantum dots (CSQDs) of II−VI (e.g., CdSe), IV−VI (e.g., PbS), and III−V (e.g., InP) compounds have to be thought over, as HPNCs behave differently. This Feature Article compares both families of nanocrystals and then focuses on approaches for substituting toxic heavy metals without sacrificing the unique optical properties as well as on surface coating strategies for enhancing the long-term stability.

[52] In addition to roughness and chemical compatibility, surface energy of TEs is also an essential factor to be considered for the efficient performance of the active materials in soft electronic devices.…”

Optoelectronic devices are advancing from existing rigid configurations to deformable configurations. These developing devices need transparent electrodes (TEs) having high mechanical deformability while preserving the high electrical conductivity and optical transparency. In agreement with these requirements, vacuum-fabricated conventional TEs based on transparent conducting oxides (TCOs) are receiving difficulties due to its low abundance, film brittleness, and low optical transmittance. Novel solution-processed TE materials including regular metal meshes, metal nanowire (NW) grids, carbon materials, and conducting polymers have been studied and confirmed their capabilities to address the limitations of the TCO-based TEs. This chapter presents a comprehensive review of the latest advances of these vacuum-free TEs, comprising the electrode material classes, the optical, electrical, mechanical and surface feature properties of the soft TEs, and the vacuum-free practices for their fabrication.
