UKM2 Chlorella sp. strain electricity performance as bio-anode under different light wavelength in a biophotovoltaic cell

A biophotovoltaic cell (BPV) is an electrobiochemical system that utilises a photosynthetic microorganism for instance is algae to trap sunlight energy and convert it into electricity. In this study, a local algae strain, UKM2 Chlorella sp. was grown in a BPV under different trophic conditions and...
