“…Even though QDs have highly desirable properties, their efficiencies in QDSSCs have been reported to be lower than that of DSSCs. To the best of our knowledge, few reports on the development or improvement of CEs are found in the literature [56,[103][104][105]. Therefore, more research should be conducted and exploited in this area.…”

Quantum dots (QDs) are semiconducting materials with diameters ranging from 2-10 nm. Amongst these QDs, nickel selenide quantum dot (NiSeQD) materials have gained much interest from researchers over the past few years due to their outstanding properties. These include excellent catalytic activity, good electrical conductivity for charge transfer, and excellent thermodynamic stability. NiSeQD material is relatively cheap, less toxic, and can be synthesised easily. Due to the fascinating and remarkable properties of NiSeQD, the material has been applied in various electrochemical fields, including hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and solar cells. This review focuses on the application of NiSeQD and its composites in the various analytical fields in the search for alternative renewable sources of energy. Interestingly, NiSeQD material can be modified with different materials to improve its sensitivity, reactivity, and limit of detection. The effects of modification with other materials such as iron (Fe), cobalt (Co), and graphene (GN) are mentioned. Additionally, the application of NiSeQD in glucose sensing is discussed briefly. In these aforementioned applications, NiSeQD has shown excellent electrocatalytic capability with satisfactory detection limits and good conductivity. Thus, further exploration of it to other fields is essential. This review highlights the importance of NiSeQD in water purification, and no report has been documented in the literature on its application in water purification. Some gaps are still open for the use of NiSeQD material as an electroactive platform for sensing devices in water treatment.

“…35 Among them, electrodeposition methods effectively control the film thickness and morphology, and are appropriate for the uniform dispersion of nanoparticles on a support at ambient temperature and pressure. 36 Because the tendency for the uniform deposition of metallic nanoparticles has grown over a short time, the use of pulse electrodeposition methods is preferred over conventional electrodeposition methods. 37 The methods used for the production of PtNi/C, 38 Pt/C, 39 and Ni-Gd 2 O 3 35 demonstrate the growing tendency to produce metallic nanoparticles with pulse electrodeposition methods.…”

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.
