Research group Solar energy and materials

Our research focuses on the development and demonstration of solutions for solar energy harvesting, spanning from crystallization of silicon for solar cells, through implementation and testing PV in use, to circular value chains and recycling of PV modules. Our competence on high temperature processing is also valuable for a range of other applications and materials.
