b'Dr. Polycarpos Falaras\\u2019 research focuses on using nanotechnology to convert solar energy to electricity; photocatalysis as an advanced oxidation process, to decompose pollutants; and carbon dioxide storage and conversion. He explains how within the photoinduced process they examine the interaction of matter -at the size of a nanometer- with light, for the creation of a new generation of photovoltaics... mentioning windows or walls that will produce electricity. He explains that although the world wide target of using solar energy as a mainstream energy source may be important it can only be realised if we reduce the final cost. In order to achieve this, Dr. Falaras points out the need for further funding when it comes to scaling up processes and materials outside the lab. He continues with his other stem of research interest, photocatalysis and how it can help in the decomposition of emerging pollutants. He analyses how they\\u2019re trying to shift from the ultraviolet spectrum (3-5% of solar light) to the broader visible light spectrum, in order to create new materials that will energise new photocatalysis reactors.
