Printing highly efficient organic solar cells

Its a very technical article, but if you can get past sentences like, “During the drying and subsequent annealing process, the solvent creates an optimum distance between the polymer and fullerene bulk heterojunction interfaces to achieve efficient charge separation of the formed exciton,” you’ll find that researchers at Konarka Technologies have been able to produce 3% efficient solar cells in a commercially available inkjet printer using special polymer inks.

Further development could make it possible to print out large scale solar cells on lightweight flexible surfaces.
