Enhanced power-conversion efficiency in polymer solar cells using an inverted device structure
typically based on n-type metal oxides, our device is solutionprocessed at room temperature, enabling easy processibility over a large area. Accordingly, the approach is fully amenable toExpand
High-Detectivity Polymer Photodetectors with Spectral Response from 300 nm to 1450 nm
This work demonstrates polymer photodetectors with broad spectral response fabricated by using a small-band-gap semiconducting polymer blended with a fullerene derivative that can exceed the response of an inorganic semiconductor detector at liquid helium temperature. Expand
Polymer solar cells: Recent development and possible routes for improvement in the performance
The development of polymer solar cells is rapidly accelerating as the need of new clean energy sources. Polymer solar cells are attractive because they can be manufactured on plastic substrates by aExpand
