This research focuses on designing and constructing a biophotovoltaic (BPV) lamp to explore the feasibility and efficiency of utilizing energy produced by plants and microorganisms for lighting LED lamps. The prototype primarily utilizes clay-based photosynthetic microbial fuel cells (PMFC) equipped with carbon, graphite, and aluminum electrodes. Additionally, it incorporates advanced technologies such as supercapacitors with ultra-fast charging times and surface-mount LED (SMD) lights that offer harmonious illumination with minimal energy consumption. A significant challenge in BPV is the low output current, as the energy is derived from the oxidation of biomass (exudates) rather than directly from the photosystems. This latter method is more complex and often directly harmful to the photosynthetic species, representing a nascent area of research. The prototype achieved a peak power output sufficient to sustain LED illumination for 9 h per day. The integration of supercapacitors substantially enhanced energy storage and delivery efficiency, thus minimizing energy loss. Although currently constrained by low output currents, the findings suggest that BPV systems have the potential to serve as a sustainable energy solution. Further development of electrode materials and configurations could improve energy harvesting capabilities, paving the way for practical applications in renewable energy. This study's results are expected to contribute to the development of innovative BPV energy harvesting techniques based on the redox effect, membrane types, electrode positioning, and electrode materials, thereby advancing the field of renewable and sustainable energy.
