Supercharged silicon wafer tandem solar cells using virtual germanium substrates. International studies show that electricity from solar cells is one of the cleanest future energy sources, able to almost completely displace fossil fuels. To fulfil such a key role, costs must greatly reduce. The project targets reduced cost by greatly improved performance by stacking high quality thin cells on top of a conventional silicon cell.
High quality copper-zinc-tin-sulphide absorber by one-stage reactive sputtering technology: a route to high efficiency/low cost thin film solar cells. International studies show that electricity from solar cells is one of the cleanest future energy sources, able to almost completely displace fossil fuels. This project, proposed to fulfil such a key role, targets greatly improved efficiency/cost ratio, by producing high quality CZTS thin film absorbers with a cost-effective fabrication technique.
Copper-zinc-tin-sulphide thin film solar cells: earth-abundant, non-toxic alternative for terawatt photovoltaics. To allow large scale implementation of photovoltaics at multi-terawatt level for a low carbon emission future, technologies are required which are high in efficiency, cheap to produce, use abundant and benign materials. This project is devoted to developing such thin film solar cells by low-cost methods, which are scalable to mass production.
