Inefficiency of the polymeric material of the photovoltaic (PV) module to shield the solar cell from UV radiation has made the maintenance cost of solar energy generation high. The results from the usage of colour plastic cellophanes as PV shield are not promising. In this study, a novel solid-state bio-filter (SSB) was synthesized using silver nitrate salt and hibiscus flower extract. The results show that the novel SSB material mitigates UV radiation via two processes i.e. reflection of UV radiation and processing of the remaining UV radiation into peaks. It was also observed that the SSB has three absorption levels and a bandgap of 3.194 eV. It is recommended that further study be carried-out to estimate the portion of UV radiation that has been reflected.
