Performance Enhancement of Polycrystalline Silicon Solar Cell through Sputter Coated Molybdenum Disulphide Surface Films

Abstract

The current research focuses on sol-gel derived synthesis and RF sputter deposition of molybdenum disulphide (MoS₂) over polycrystalline Si solar cell. Various coating layers were obtained under different sputter deposition at regular intervals. The influence of MoS₂ sputter coating on optical, thermal chemical structural properties was examined through various characterisation techniques. 30 minutes coated solar cell reported maximum light transmittance of 95 % in the visible spectrum and minimum electrical resistivity of 2 × 10^-3ohm-cm. 30 minutes coated solar cell exhibited maximum power conversion efficiency (PCE) of 19.19 % (open source) and 21.01 % (controlled source). Thermal imaging data reveal that the optimal coating layer experiences a minimum temperature of 33.9 °C and 49.9 °C. From experimental results, sputter deposited MoS₂ Si solar cells experience minimum light reflectance and enhanced cell performance.
