Abstract

This study investigates the effectiveness of plasmonic improvement on photonic absorber properties of capped SiO2 and TiO2 nanoparticle in thin film a-Si photovoltaic cell. It also examines their J-V properties when exposed to sunlight. The modified Stober approach was used for irradiation tests, revealing lower reflectivity in different doses with SiO2 1st dose:0.485mg/ml, SiO2 2nd dose:0.693mg/ml, and TiO2 1st dose:0.525 mg/ml, TiO2 2nd

dose:0.748 mg/ml solutions. Silica-based solar cells showed a 2.45% efficiency improvement, while titania-based solar cells improved efficiency by 0.657% compared with the uncoated sample.
