In order to support the enormous pressure exerted by the continuous growth in energy demand, combined with the climatic and environmental repercussions linked to the exploitation of typically non-renewable energy sources, technological innovation leads the strategies for global economic and social progress. This aims towards the development of new materials and techniques for the energy conversion and production from clean and sustainable sources.
Solar radiation is among the most promising alternatives, as well as the most abundant, nevertheless current technology still struggle to exploit its full potential. One of the cornerstones for improving and optimizing the conversion of solar energy also concerns its long-term sustainability, or, in other words, its storage. One of the solutions that currently attracts a lot of research attention concerns the possibility of combining in a single compact system the two processes for energy exploitation, that is the conversion and storage of solar energy, normally carried out separately. The objective, in this context, concerns the research and study of materials or combinations of materials that are able to support the mechanisms behind the aforementioned processes, which would be absorption of light, separation of charges, their accumulation, but also the final transport for their release “on demand”. Naturally, sustainable development strategies also concern the cost-effective production and preparation methods and must aim at the use of non-critical raw materials.
In this work, emerging materials and systems in the field of light driven applications for the solar energy conversion and storage will be presented and discussed. In particular, the development of systems based on the combination of Transparent Conductive Oxides (TCO) nanocrystals and Transition Metal Dichalcogenides (TMDC) 2D materials will be examined giving their potential and interesting possibility of multi-charge transfers.
