Spectral filtering of photovoltaic cells using novel bio-filter: Silver coated ixora extract using methanol solution

Abstract

Photovoltaic (PV) solar panel imported into Africa was observed to have low lifespan due to the spectrum of harmful solar radiation hitting the surface of the PV panel. In this research, the bio-filter was synthesized using plant extract and silver. The dark room experiment was carried out to examine capacity of the PV panel accept specific radiations. The bio-filter was sprayed on the PV panel and the measurement for a sprayed and unsprayed PV panel were obtained. It was discovered that the bi-filter was effective to stabilize the measured parameters such as current, voltage and power.
