Transparent zinc sulfide (ZnS)-aluminium sulfide (Al2S3) 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-Al2S3) and its average crystallite size is 15.83 nm. The minimum electrical resistivity (q), maximum hall mobility (l), and carrier concentration (N) of ZnS-Al2S3 nano-layer coated solar cells are measured to be 2.98 9 103 X cm, 14.89 cm2 V1 s1 and 24.88 9 1020 cm3 respectively. For a time period of 25 min, ZnS-Al2S3 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-Al2S3 nano-layer coated silicon solar cells is observed. The ZnS-Al2S3 composite demonstrates the properties of a desirable anti-reflection coating material for enhancing the PCE of solar cells.

device that converts light energy into electrical energy through the photovoltaic effect. The elementary material used for the fabrication of solar cells is silicon.4 High-performance polycrystalline silicon solar cells enhance the light transmittance characteristics with lower optical loss. The power conversion efficiency (PCE) of a silicon solar cell depends on its surface reflections. Anti-reflection coating (ARC) plays a key role in enhancing the PCE of solar cells by reducing the reflection losses in the solar cell.5,
