Why 'baking powder' increases efficiency of plastic solar cells

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 ...

Solar cell polymers with multiplied electrical output

One challenge in improving the efficiency of solar cells is that some of the absorbed light energy is lost as heat. So scientists have been looking to design materials that can convert more of that energy into useful electricity. ...

New materials yield record efficiency polymer solar cells

Researchers from North Carolina State University and Hong Kong University of Science and Technology have found that temperature-controlled aggregation in a family of new semi-conducting polymers is the key to creating highly ...

Blades of grass inspire advance in organic solar cells

Using a bio-mimicking analog of one of nature's most efficient light-harvesting structures, blades of grass, an international research team led by Alejandro Briseno of the University of Massachusetts Amherst has taken a major ...

Organic tin in polymers increases their light absorption

Researchers of the Christian-Albrechts-University of Kiel (CAU), Germany, successfully integrated organic tin into semiconducting polymers (plastics) for the first time. Semiconducting polymers can be used, for example, for ...

Self-organized indium arsenide quantum dots for solar cells

Kouichi Yamaguchi is internationally recognized for his pioneering research on the fabrication and applications of 'semiconducting quantum dots' (QDs). "We exploit the 'self-organization' of semiconducting nanocrystals by ...
