Quantum dot sensitized solar cells using type-II CdSe-Cu2Se core-shell QDs
No full textOleylamine capped CdSe-Cu2Se type-II core–shell quantum dots were synthesised by organometallic high temperature route. The nanostructures were characterized using XRD, XPS, HRTEM, optical absorption and EDS and their suitability to serve as an effective sensitizer for TiO2 deposited fluorine doped tin oxide coated glass slides was explored. Employing aqueous sulfide/polysulfide redox couple as the electrolyte, Cu2S as the counter electrode, ZnS as the surface passivation layer and TiO2 as the anode material, quantum dot sensitized solar cells were constructed. A power conversion efficiency of 4.3% was observed for the best performing device. Sintering of the photoanode, before embedding in the cell structure, resulted in an efficiency enhancement to 4.83%
An investigation on the synthesis and characterization of MoS2 nanoflowers draped g-C3N4 nano sheet (g-C3N4 / MoS2 / MnOOH) ternary composite for the efficient photocatalytic applications
No full textIn this study,MoS2/g-C3N4Nano flower like composite is synthesizedusing hydrothermal procedure to identify its photo catalytic properties on Methyl Dyes. The morphology, structure and optical properties of the produced materials are studied by X-Ray Diffraction, Fourier Transform Infrared Spectroscopy, FESEM, EDAX and UV –Vis Spectroscopy. The results received through characterizations confirmed that g-C3N4nanosheets are embedded with flower-like MoS2.The construction of the hetero junction is successful and widened absorptionrange in visible light is identified. Iste water contaminated by methyl dyes can be purified using thesynthesized composite. The suitability of the synthesized composite can be efficient in the removal of methyl dyes from industrial istes and domestic istes
