New path to more efficient organic solar cells
30 January, 2013For polymer-based organic photovoltaic cells, which are far less expensive to manufacture than silicon-based solar cells, scientists have long believed that the key to high efficiencies rests in the purity of the polymer/organic cell’s two domains - acceptor and donor. Now, however, an alternate and possibly easier route forward has been shown.
