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.
