Spectral Filtering of Photovoltaic Cells using Novel Bio-Filter: Silver Coated Hibiscus Extract using Water Solution

Abstract

The photovoltaic (PV) technology has evolved over the years based on the three main challenges i.e. efficiency, longevity and cost. Till date, there had not been a precise solution to the negative effect of solar IR radiation on the longevity of PV panels. In this research, the bio-filter was synthesized to filter harmful solar radiation. Bio-filter is made up of metallic coated plant extract. The monocrystalline and polycrystalline PV panel were used to test the performance of the bio-filter. It was observed that the bio-filter optimized the current generation in the panel to about 3%.
