Solar energy: Dyes help harvest light

30 julio 2014

A new dye-sensitized solar cell absorbs a broad range of visible and infrared wavelengths. Dye-sensitized solar cells rely on dyes that absorb light to mobilize a current of electrons and are a promising source of clean energy. Scientists have now developed zinc porphyrin dyes that harvest light in both the visible and near-infrared parts of the spectrum.
