Bioelectricity and electrogenesis: "Bioelectricity here means the flow of electrons that occurs as a result of biological reactions occurring in plants and algae. Such electrical flows can be considered a form of renewable energy as they are ultimately driven by solar energy. The process of electron production is called electrogenesis: Photopigments within each cell capture and absorb photons of light to generate high-energy electrons. During photosynthesis virtually every photon absorbed by chlorophyll pigments within the cell can eject one electron; this is the mechanism behind the genesis of electrons (which are able at low efficiency to escape from the cells and be harvested in the form of an electron current). Different types of biological material have been shown to be able to produce an electrical current in response to light. They include plants such as moss but also simpler chemical systems composed of isolated purified photosystems (macromolecules responsible for photosynthetic reactions). However, algae are particularly advantageous due to their physiological simplicity and the fact that live cells are able to rebuild photosynthetic complexes when they become damaged and so maintain long-lived electron flow (Komenda, Michoux, Nixon 2012)."
