MIT researches have managed to use a plant’s ability to convert sunlight to energy into a solid-state electronic battery device. The Photosystem I (PSI) was derived from spinach chloroplasts, it measures about 10 to 20 nanometers, about 100,000 of them can fit on a pin head. These could very well be the smallest electronic circuits every designed. “We have crossed the first hurdle of successfully integrating a photosynthetic protein molecular complex with a solid-state electronic device,” Baldo said.
