Illumination of the back-side of a UV transparent medium significantly reduces the decomposition of organic pollutants to carbon dioxide while significantly increasing the amount of radiation available for catalysis of the organic pollutants by a photocatalytic semiconductor. The UV light illuminates the UV transparent medium such that the UV propagates through the medium, illuminating the back-side of a photocatalytic semiconductor coating on the front-side. The photocatalytic semiconductor dissociates water on its surface to form hydroxyl radicals which in turn oxidize organic pollutants.
