Proficient One-Step Heat-Up Synthesis of Manganese Sulfide Quantum Dots for Solar Cell Applications

“…Ammonium N -piperidinyldithiocarbamate was prepared according to the literature [ 1 ]. A volume of 9.9 mL (0.1 mol) of piperidine was added to 30 mL of ammonium solution with 6.04 mL (0.1 mol) of carbon disulfide in a dropwise reaction at 5 °C and stirred for 1 h to precipitate.…”

“…Semiconductor quantum dots (QDs) employed as photosensitizers with tunable band gaps as an alternative to dye-sensitized solar cells (DSCs) has attracted increasing attention from researchers in recent years. QDs have a unique absorption coefficient for large light, with high stability due to their tunable band gap [ 1 , 2 , 3 , 4 , 5 ]. The use of QD photosensitizers from inorganic semiconductors is gaining increasing attention, with more studies being conducted due to their advantages relative to homologue dyes [ 1 , 2 , 3 ].…”

The use of QD photosensitizers from inorganic semiconductors is gaining increasing attention, with more studies being conducted due to their advantages relative to homologue dyes [ 1 , 2 , 3 ]. Owing to their physical and chemical properties, chalcogenide metal compounds, such as manganese, have recently received a considerable amount of attention as modern, innovative technology in a variety of fields [ 6 ].…”

“…Various approaches have been reported for the preparation of MnS through hydrothermal, solvothermal, chemical bath deposition (CBD), chemical vapor deposition (CVD) and successive ionic layer adsorption and reaction (SILAR) [ 17 , 18 ]. A single-source method produces high-purity and cost-effective materials by incorporating the required elements into one compound [ 1 , 2 , 3 ]. This approach involves a simple decomposition of the molecular precursor, usually dithiocarbamate metal complexes, in an inert environment to the desired temperature [ 19 , 20 , 21 ].…”

Zn-doped SnS with sulfur vacancies for enhanced photocatalytic hydrogen evolution from water

“…26 This unique property determines its widespread application prospects in many fields such as transistors, 27 optoelectronic detectors, 28 supercapacitors, 29 Li-ion batteries, 30 and solar cells. 31 In terms of photocatalysis, it is mainly used for photocatalytic degradation of organic matter 32 and gas detection, 33 but there is a lack of research on its use in photocatalytic water splitting due to its conduction band position, and it does not meet the potential requirements for the reduction of H + to H 2 from water. 34 Several reports theoretically demonstrated that SnS has photocatalytic water splitting ability with suitable nanostructures, 25,26 but it has not been experimentally verified.…”
