Confocal fluorescence lifetime images of conjugated honeycomb, of polymer/fullerene honeycomb double layer and of polymer/fullerene honeycomb blend. Efficient charge transfer within the whole framework is observed in the case of polymer/fullerene honeycomb blend as a dramatic reduction in the fluorescence lifetime
While rooftops are the obvious place to put solar cells to generate clean electricity for the home, we’ve seen a number of technologies aimed at expanding the potential solar collecting area to include windows using transparent solar cells. These include Octillion Corp’s NanoPower Window technology, RSi’s semi-transparent photovoltaic glass windows, and EnSol’s transparent thin film. In this latest development, U.S. scientists have fabricated a new type of self-assembling transparent thin film material that could boost the cost effectiveness and scalability of solar window production.
