Abstract
- Transparent zinc sulfide (ZnS)-aluminium sulfide (Al<subscript>2</subscript>S<subscript>3</subscript>) composite thin-films are deposited on silicon solar cells through radio frequency (RF) sputtering method at room temperature to investigate the structural, optical, electrical, and thermal characteristics. X-ray diffraction analysis reveals the presence of the powder sample (ZnS-Al<subscript>2</subscript>S<subscript>3</subscript>) and its average crystallite size is 15.83 nm. The minimum electrical resistivity (ρ), maximum hall mobility (μ), and carrier concentration (N) of ZnS-Al<subscript>2</subscript>S<subscript>3</subscript> nano-layer coated solar cells are measured to be 2.98 × 10<superscript>−3</superscript> Ω cm, 14.89 cm<superscript>2</superscript> V<superscript>−1</superscript> s<superscript>−1</superscript> and 24.88 × 10<superscript>20</superscript> cm<superscript>−3</superscript> respectively. For a time period of 25 min, ZnS-Al<subscript>2</subscript>S<subscript>3</subscript> nano-layer sputter coating produces the maximum power conversion efficiencies (PCE) of 19.38% and 21%, obtained at open and controlled atmospheric conditions, respectively. The influence of operating temperature at both these open and controlled atmospheric conditions for ZnS-Al<subscript>2</subscript>S<subscript>3</subscript> nano-layer coated silicon solar cells is observed. The ZnS-Al<subscript>2</subscript>S<subscript>3</subscript> composite demonstrates the properties of a desirable anti-reflection coating material for enhancing the PCE of solar cells.
