Scientists have reported that the current harsh weather conditions are capable of destroying the solar cells of PV panels. In this research, the bio-filter was introduced to undertake spectra filtering of solar radiations hitting the surface of the PV panel. The bio-filter was made up of hibiscus extract in water solution and copper (II) nitrate tri-hydrate. The performance of the bio-filter was noticeable but very significant because of the multi-components of the hibiscus extract that have structural disadvantage to accommodate copper coating. Further research is thereby recommended to seek ways of removing the cyclopropanoids and malvalate before coating it with copper. ER -
