“…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.

“…Other deposition techniques such as the successive ion layer absorption and reaction (SILAR), Pulsed Laser Deposition (PLD) 11 12 13 and chemical bath deposition (CBD) are routinely used in situ methods to prepare QDSSCs 7 . So far, CdS 14 15 16 and CdSe 17 18 19 20 21 are the most investigated metal chalcogenides in NiO-based p-QDSSCs, although Cu 2 S 22 , CdTeO 3 23 and more recently CuInS 2 were reported 24 25 . Frank and co-workers 26 , have reported very fast hole transport times for NiO film sensitized with CdS QDs, resulting in an almost quantitative charge collection efficiency.…”

Sensitized NiO based photocathode is a new field of investigation with increasing scientific interest in relation with the development of tandem dye-sensitized solar cells (photovoltaic) and dye-sensitized photoelectrosynthetic cells (solar fuel). We demonstrate herein that PbS quantum dots (QDs) represent promising inorganic sensitizers for NiO-based quantum dot-sensitized solar cells (QDSSCs). The solar cell sensitized with PbS quantum dot exhibits significantly higher photoconversion efficiency than solar cells sensitized with a classical and efficient molecular sensitizer (P1 dye = 4-(Bis-{4-[5-(2,2-dicyano-vinyl)-thiophene-2-yl]-phenyl}-amino)-benzoic acid). Furthermore, the system features an IPCE (Incident Photon-to-Current Efficiency) spectrum that spreads into the infra-red region, reaching operating wavelengths of 950 nm. The QDSSC photoelectrochemical device works with the complexes tris(4,4′-ditert-butyl-2,2′-bipyridine)cobalt(III/II) redox mediators, underscoring the formation of a long-lived charge-separated state. The electrochemical impedance spectrocopy measurements are consistent with a high packing of the QDs upon the NiO surface, the high density of which limits the access of the electrolyte and results in favorable light absorption cross-sections and a significant hole lifetime. These notable results highlight the potential of NiO-based photocathodes sensitized with quantum dots for accessing and exploiting the low-energy part of the solar spectrum in photovoltaic and photocatalysis applications.
