Syfte och mål

Photosynthetic plants, algae, and bacteria harvest a vast amount of solar energy, and provide it as a source of life energy on Earth, sustaining the food chain, creating fossil fuels, and oxygen. The goal of this project is to demonstrate Solar Energy Harvesting Devices based on Photosynthetic Organisms integrated with Organic Bioelectronic Electrodes.

Förväntade effekter och resultat

The experienced researcher will realize direct photocurrent harvesting from plants, bacteria, and algae using PEDOT-NFC as a flexible bio-organic electrode. The potential of this approach for energy harvesting by using photo-electrochemical, DSSC, and bio-photovoltaic (BPV) setups will be explored. Expected effects: (1) source of electrical energy, (2) enhanced natural photosynthesis to yield more efficient plant growth, helping to resolve the global food source problem, (3) study of basic scientific concepts related to biology and bioengineering.

Planerat upplägg och genomförande

Phase 1 will test the polymer in DSSC as electrode with thylakoid membranes. In Phase 2 living photosynthetic organisms will be integrated with PEDOT-NFC electrode via modification of the pore size of PEDOT to accommodate microorganisms, including testing for energy extraction, surface structure (atomic force microscope (AFM)), and dielectrical properties (impedance spectroscopy). Direct contact of bacteria with electrode, and using redox mediators will be tested. Finally, solar bio energy harvesting devices DSSC and BPV will be constructed and evaluated.
