Researchers have boosted the efficiency of organic solar cells by 20 percent through the use of gold nanoparticles (Image: Gold nanoparticles in nanowires - Argonne National Laboratory)
Carbon-based organic photovoltaic cells, which use organic polymers or small molecules as semiconductors, are significantly thinner and cheaper than their inorganic silicon-based counterparts. Unfortunately, they are also much less efficient at converting sunlight into electricity. That could be on its way to changing, however, as an international team of researchers have reportedly boosted the efficiency of organic photovoltaic cells by 20 percent ... with some help from gold nanoparticles.
