The demand for truly green energy solutions is increasing both as a necessity worldwide and as a requirement in more energy progressive jurisdictions. Melanin, a non-toxic and widely available biopolymer, has shown some promise in past research as a candidate for truly clean energy storage and production. With potential applications in the biotechnology field, where non-toxicity is imperative, this body of work sets out to engineer a proof of concept melanin-aqueous electrochemical cell, which converts incident electromagnetic radiation into useful electrical energy. Fungal and bacterial melanin were utilized in differ- ent concentrations in melanin aqueous cells. After comparing the multiple cells constructed, the results revealed the bacterial melanin electrochemical cell with a 1% concentration of melanin by weight to have the best performance. Analysis of the voltage output demonstrates reactivity to incident artificial solar radiation and a recorded power density of 268 μW/L.
