Novel Composite Oxides by Combinatorial Material Synthesis for Next Generation All-Oxide-Photovoltaics (ALLOXIDEPV)
Date du début: 1 nov. 2012, Date de fin: 31 oct. 2015 PROJET  TERMINÉ 

The global market for photovoltaic (PV) cells that are converting sunlight into electricity almost doubled in 2010 to reach a massive 18.2 GW, nearly three times size of the market back in 2008. Crystalline silicon is the most common PV material today with a market share of more than 80%. New developments such as electrolyte based dye-sensitized solar cells as well as organic polymer cells have experienced remarkable progress in the laboratory but penetration into the market is still far away due to stability and sealing problems. Thus, this project will develop all-oxide photovoltaic cells based on nano-composite materials using combinatorial synthesis methods in conjunction with large throughput characterization and computational data analysis. Oxides are chemically stable, many of them are not hazardous, abundant and can furthermore be produced by low-cost methods. To challenge the inherent limitations of pure oxide semiconductors novel composite materials consisting of two or more pure metal oxides using various mixing ratios will be developed. Moreover, new fabrication techniques, powerful characterization tools and computational analysis methods will be employed that have not been available yet for material science. Combinatorial synthesis methods used in biology, chemistry and pharmaceutical research will be adopted to screen efficiently through a large amount of oxide compositions.
