“…Cao et al [ 42 ] reported on the heterojunction structure of NiS2/MnS with 6.44 % and 4.81% for MnS FTO as a potential counter electrode to replace Pt as a low-cost and highly efficient material for dye-sensitized solar cells. Based on electrochemical, structural and optical analyses, the γ-MnS phase was investigated as an anode material and as efficient visible light emitters with improved cycling stability for Li-ion batteries [ 43 , 44 , 45 ]. The band-gap energy at 3.78–4.0 eV and the high emission intensity in the present study are strong indications that these materials can absorb the entire solar spectrum, improving efficiency in solar cell applications.…”

The necessity to develop renewable energy resources that are highly durable and flexible with superior energy density and capacitance ability has attracted considerable interest in the field of solar cell research. Semiconducting compound materials that are easily available, hazard-free and cost-effective are emerging as potential solutions to tackle this challenge. Herein, we present multiple molecular precursors used to grow manganese sulfide nanoparticles through a proficient one-step heat-up approach. For all of the tested samples, the X-ray diffraction peaks correspond to a γ-MnS hexagonal wurtzite structure. UV-Vis spectroscopy yielded absorption wavelengths of 359–420 nm and band-gap energies of 3.78–4.0 eV. Photoluminescence analysis shows characteristics of red and blue shift from 451–602 nm. High-resolution transmission electron microscopy (HRTEM) and selected-area electron diffraction (SAED) reveal a narrow size distribution with nanosticks and large contact areas, which are critical for improved catalytic performance. The current study provides an improved pathway to a well-grown and uniform nanocrystal structure for applications in energy devices.

The conditions for the fabrication of n-NiS2/n-CdTe isotype heterojunctions with diode properties by spray pyrolysis of n-NiS2 thin films on n-CdTe crystalline substrates have been studied. The temperature dependence of the current-voltage characteristics is analyzed, and the mechanisms of the current generation at the heterojunction at forward and reverse voltages are determined. Based on the analysis of the capacitance-voltage characteristics, a model of a double Schottky diode for the studied heterojunction is presented, which well describes the observed electrophysical phenomena.
