Any substance that has enhanced reactivity, or altered properties in the presence of light is said to be photoreactive. For example, a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. Photoreactive substances can either be natural, such as chlorophyll, or entirely man-made in the case of a photovoltaic cell.
