Biophotovoltaics (BPV) offers a clean energy solution using photosynthetic organisms. This review covers BPV materials, methods to boost photocurrent, and limitations for future development.
Area of Science:
- Biotechnology
- Renewable Energy
- Photovoltaics
Background:
- Biophotovoltaics (BPV) presents a sustainable alternative to traditional photovoltaics, offering self-repair and natural degradation.
- BPV systems utilize photosynthetic organisms to convert light energy into electrical energy.
- Key challenges include efficient electron transfer from biological materials to electrodes.
Purpose of the Study:
- To review current biological materials used in biophotovoltaics.
- To discuss strategies for enhancing photocurrent output in BPV systems.
- To identify limitations and propose future research directions for BPV biological components.
Main Methods:
- Review of literature on cyanobacteria, green algae, microbial consortia, and isolated photosynthetic components (thylakoids, photosystems) for BPV.
- Analysis of techniques employed to improve electron transfer and photocurrent generation.
- Identification of biological material limitations impacting BPV performance.
Main Results:
- Cyanobacteria, green algae, microbial consortia, and isolated photosystems are primary biological materials in BPV.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
