“…As the nickel selenide showed high catalytic activity toward iodide redox couple [85] , several groups repeated this experiment under different conditions and achieved the same results. Wu and co-workers synthesized Ni 0.85 Se film on FTO glass by a facile one-step hydrothermal reaction and a spin-coating method, which could be used as CE in DSCs [92] . The Ni 0.85 Se electrode showed high transmittance, which made it suitable for bifacial DSCs.…”

“…Pt layered fluorine-doped tin oxide (FTO) glass counter electrodes are most commonly used for DSSCs because of their high reflectivity and excellent catalytic activity. However, Pt-based counter electrodes are expensive, energy-intensive, and translucent. , Thus, alternative counter electrode materials, such as transparent metal alloys, conductive polymers, or carbon nanoparticles, have gained popularity. CQDs have been primarily doped to these alternative counter electrode materials.…”

Interest in carbon quantum dots (CQDs) has recently boomed due to their potential to enhance the performance of various solar technologies as nontoxic, naturally abundant, and cleanly produced nanomaterials. CQDs and their other variations, such as nitrogen-doped carbon quantum dots (NCQDs) and graphene quantum dots (GQDs), have improved the performance of luminescent solar concentrators (LSCs) and photovoltaic (PV) cells due to their excellent optical properties. As fluorophores in LSCs, CQDs are mostly transparent to visible light and have absorption/re-emission spectra that can be easily controlled. The outstanding optical properties of CQDs make them promising materials to replace expensive, heavy-metal-based fluorophores. Various CQDs have also been used as or doped into the photoanode, counter electrode, hole transport layer (HTL), and electron transport layer (ETL) of dye-sensitized solar cells (DSSCs), organic solar cells (OSC), perovskite solar cells (PSCs), and other PV cell configurations. The addition of CQDs into the various solar cell components has reduced electron recombination, increased charge density, and boosted electron mobility, improving the performance of the PV cells. Enhancing the power conversion efficiency (PCE) of photovoltaic devices is essential in propagating green energy technology. Thus, CQDs offer an affordable, safe, and environmentally friendly method to advance photovoltaic performance.

We have reported the formation of a thin manganese cobalt sulfide (MCS) film on a fluorine-doped SnO 2 (FTO) substrate by a facile electrodeposition method for fabricating quantum-dot-sensitized solar cells (QDSSCs). The resulting FTO/MCS films are subsequently employed as counter electrodes (CEs) for cadmium selenide-based QDSSCs. The QDSSC with the FTO/MCS CE provided significantly enhanced short circuit current and fill factor, resulting in very high overall energy conversion efficiency (3.22%) compared to that with the Pt CE (1.08%) under 1-sun illumination. This can be attributed to the significantly enhanced electrocatalytic activity and superior electrical conductivity of the binary transition metal sulfide in addition to the excellent electrical contact at the interface between the electrodeposited MCS film and the FTO. Furthermore, the FTO/MCS exhibit excellent electrochemical stability, unlike the conventional Pt CE. These findings suggest that FTO/MCS should be a promising electrocatalytic electrode material for practical energy conversion applications.
