Abstract: The novel light conversion system includes photosensitive optoelectronic devices, or photovoltaic cells, that convert electromagnetic radiation into electrical currents without applying an external voltage. Power conversion efficiency is a primary criterion for evaluating the performance of photovoltaic cells. Photovoltaic cells with high power-conversion efficiencies are more cost effective and more suitable replacements for conventional energy sources. This novel light conversion system uses a polycrystalline organic material with unique material properties for achieving high, power-conversion efficiencies.
