Abstract

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.

Highlights

  • The need for energy increased as technology evolved

  • The results show that the novel solid-state bio-filter (SSB) material mitigates UV radiation via two processes i.e. reflection of UV radiation and processing of the remaining UV radiation into peaks

  • Despite the solar irradiance pattern seen on the voltage outcome, it was observed that the SSB absorbance had three basic absorption levels that controls it

Summary

Introduction

The need for energy increased as technology evolved. Energy generation has evolved as more efficient ways of generating energy from a single process are discovered. The hydropower plant, coal power plant and nuclear power plant are typical example of a single source energy generating process that can generate huge energy [1,2,3]. Almost all countries in the world have adopted hydropower plant, coal power plant or nuclear power plant. A public report claimed that the amount spent by populace in some developing countries on fossil fuel generator is above the health or education budget of the nation [45]. The fossil fuel generator (FFG) has gained huge momentum in the global market with sizeable population employed directly or indirectly
