The use of carbon dioxide emissions as a raw material, e.g. for the chemical industry and for the production of synthetic fuels, is regarded as an alternative to its storage, as the potential benefits are dual: emissions are removed at the same time as greenhouse gases from the substitution of conventional goods are avoided. However, there is an outstanding lack of information on the overall carbon dioxide balance for these new approaches. This paper performs...

Standard photovoltaic solar cells (PV cells) use only about half of the light spectrum provided by the sun. The infrared part is not utilized to produce electricity. Instead, the infrared light heats up the PV cells and thereby decreases the efficiency of the cell. Within this research project, a hybrid solar cell made of a standard PV cell and a thermally driven thermoelectric generator (TEG) is being developed. The light of the sun splits at...
