Kim Bini   PhD 2014 -2018

After earning his M.Sc. in Biotechnology at Chalmers University of Technology, Kim Bini started his PhD studies in March 2014 at Applied Chemistry. His research is focused on developing pathways to green solvent processing of active layer materials for polymer solar cell applications. Organic photovoltaic devices show great promise and might change the world from fossil fuel dependence to solar powered. In order to make this technology truly green, the pervasive usage of chlorinated solvents for processing needs to be changed. This project aims to solve that problem with the usage of thermocleavable sidechains, leading to a switchable solubility.​
