Green machine is our weekly column on the latest advances in environmental technologies.
Silicon solar cells are so, well, dead. Dollops of green goo made of living cells – from jellyfish to algae - are now being recruited to produce cheaper solar power.
Zackary Chiragwandi at Chalmers University of Technology in Gothenburg, Sweden, and colleagues are developing a photovoltaic device based on green fluorescent proteinMovie Camera (GFP) from the jellyfish Aequorea victoria.
The team deposit two aluminium electrodes with a tiny gap between them onto a silicon dioxide substrate. A droplet of green fluorescent protein is then added on top, whereupon the protein assembles 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.
