Thank you for this meaningful post. Hope to see your more experiences about this topic. Harvesting electricity from plants must be new tendency in the world... Normally photosynthetic plants capture the sunlight and convert it to sugar in the way of photosynthesis. When the photosynthesis stopped, then it means that electrons are not used for photosynthesis anymore (but can be used for producing energy)...University of Georgia has good researched about producing energy from the green plants.
