Why 'baking powder' increases efficiency of plastic solar cells

(Feb.6, '15) The efficiency of plastic solar cells can be doubled or tripled if an extra solvent is added during the production process, comparable with the role of baking powder in dough mixture. Exactly how this works has been unclear for the last ten years. But now researchers at TU/e have come up with the answer in a publication in Nature Communications. This new understanding will now enable focused development of plastic solar cells.
