Moss Voltaics is a green façade system that aims to explore how moss might be used as a source of renewable energy and how it can be implemented to the urban scale.
Mentioned emerging technology is called bio-photovoltaics (BPV) which uses the natural process of photosynthesis to generate electrical energy. In this process, plants using light energy consume carbon dioxide and water from the environment to convert it into organic compounds. Those compounds are required for the vital processes of a plant.
“When the moss photosynthesises, it releases some of these organic compounds into the soil which contains symbiotic bacteria. The bacteria break down the compounds, which they need to survive, liberating by-products that include electrons.”
By providing an electrode for the micro-organisms to donate their electrons to, the electrons can be harvested as electricity.
