(PhysOrg.com) -- Porphyrins are most commonly thought of as the pigment in red blood cells, but now scientists have found that porphyrins can also be used to increase the efficiency of an inexpensive type of solar cell. In a recent study, researchers have found that a variety of porphyrin arrays can improve the solar-to-electrical energy conversion efficiency of dye-sensitized solar cells (DSSCs), and could potentially be used to construct larger 3-D light harvesting arrays.
