“…Specific metal sulfides such as Cu x S, CoS, PbS, NiS, MoS 2 have good catalytic activity in the polysulfide electrolyte and low production cost. [126,128,[133][134][135][136][137] However, it may have the disadvantages of low electrical conductivity and low stability due to corrosion with the electrolyte. [133,138,139] The two most common methods of manufacturing metallic sulfides are: 1) deposition of the film on a transparent conductive glass substrate (the most common is FTO: fluorine-doped tin oxide); 2) growth of the material by the in situ method, which occurs on a metal or oxide surface.…”

Energy demand, global warming, environmental impacts, sustainability, and energy sources are some of the concerns faced by humanity. Quantum‐dot‐sensitized solar cells (QDSSC) are an alternative solution to addressing some of these issues, in addition to reducing the costs of producing electrical energy. However, QDSSCs present stability problems and low efficiency, less than 16%. In light of this challenge, this review aims to present the main strategies adopted to reduce energy losses that occur in each component of the solar cell, with a focus on one key component: the counter electrode (CE). The CE plays a crucial role in collecting electrons and regenerating the electrolyte, thus impacting the lifespan and efficiency of QDSSCs. As such, this review discusses the main advancements in CEs based on key materials such as metal sulfides, carbonaceous materials, and composites. The efforts related to the synthesis and application of different counter electrodes for QDSSCs are explored.

“…Here, J lim is the value of the point at which the curve in the diffusion zone intersects with the y-axis, which is decided by the diffusion rate of the redox pair of the electrolyte. Further, J 0 is the value of the intersection point of the maximum tangent lines of the two polar curves, which is related to the electron exchange rate on the electrode surface [39,40]. According to the Tafel equation [41] the corresponding values can be obtained as follows:…”

In this work g-C3N4/CuS composite film was prepared by successive ion layer adsorption and reaction (SILAR) method and used as the counter electrode in quantum dot sensitized solar cell (QDSSCs). To configure the cell, CdSe and CdS quantum dots acted as sensitizers on the photoanode side, polysulphide was used as the electrolyte and copper sulphide was deposited into the g-C3N4 film structure on the counter electrode side. Scanning electron microscope and X-ray diffraction were used to characterize the morphology and structure of the electrode materials, respectively. The photovoltaic performance of the cell was analysed by a standard solar simulator. The results revealed that the photoelectric conversion efficiency of the cell reached 3.65% under condition of AM 1.5 and irradiation intensity of 100mW/cm2.
