We've discussed Polymer solar cells, and its efficency ratings in a previous article as it recorded its highest efficiency. Again research has pushed the boundary with a slight chance of increasing this efficiency ratings even higher.
As we know, polymer or plastic solar cells are made up of sustainable materials, that make it flexible and very light. The problem has always been with its power-conversion efficiency--in which a research team led by Professor Tobin J. Marks of Northwestern University seem to have improved. They have designed and synthesized polymer semiconductors with fill factors of 80%--very close to silicon solar cells. This study has been published in the journal Nature Photonics.
Why this is useful: "Our results indicate that the power-conversion efficiency achievable with polymer solar cells may be far beyond the current levels, heralding a bright future for this technology. With our high fill factors, polymers with very good but not champion light absorption still are able to achieve very good efficiency." States Professor Tobin J. Marks (reference).
