Prototype Biophotovoltaic devices have recently been constructed and tested in the laboratory, but a great deal of research is required in order to develop BPV into a commercially viable technology. Low cost BPV devices may become competitive alternatives to conventional renewable technologies such as bio-fuels in the next 10 years.
