Getting energy from jellyfish
Zackary Chiragwandi and his colleagues at Chalmers are developing a photovoltaic device based on green flourescent protein, GFP, from jellyfish.
The researchers deposit two aluminium electrodes with a very small gap between them onto a silicon dioxide substrate. A drop of green fluorescent protein from the jellyfish Aequorea victoriais added. This causes the protein to assemble itself into strands between the electrodes.
When exposed to ultraviolet light, the GFP absorbs photons and emits electrons, which travel around a circuit to produce electricity.
