Study of defect density of copper vacancies in chalcogenide CuSbS, CuSbSe, CuBiS, and CuBiSe heterojunction thin-film solar cells.

In the past decade, a new family of ternary chalcogenide absorber (TCA) materials MMX (where M = Cu, Ag, Pb; M = Sb, Bi, In; and X = S, Se, Te) have been studied. The copper family of ternary chalcogenide CuSbS CuSbSe CuBiS, and CuBiSe is an amazing absorber material for thin-film solar cells because of their suitable band gap, high absorption coefficient and inexpensive, nontoxic, environment friendly and sustainable nature. In the presented work, first time simulated defect density of copper vacancies in CuSbS (CAS), CuSbSe (CASe), CuBiS (CBS) and CuBiSe (CBSe) has based heterojunction thin-film solar cells (HJTFSCs) with buffer CdS, intrinsic i-ZnO, window ZnO: Al and back contact Mo and set the cell scheming ZnO: Al/i-ZnO/n-CdS/p-TCA/Mo using SCAPS 1D.

Role of rare-earth oxides, conjugated with [Formula: see text], in the enhancement of power conversion efficiency of dye sensitized solar cells (DSSCs).

Different rare-earth (RE) metal-oxides nano-particles (NPs) viz. Samarium (III) oxide (SmO), Neodymium (III) oxide (NdO), and Gadolinium (III) oxide (GdO) were synthesized using co-precipitation route, and investigated by structural, optical, and morphological studies. Findings and supporting studies were presented to understand the role of RE-metal-oxides NPs as photo-anode material for dye sensitized solar cells (DSSCs) applications.
