Recently we can observe growing interest in organic photovoltaic cells. Nowadays, when the development of renewable sources of energy is necessary, photovoltaic energy becomes an opportunity to reduce consumption of fossil fuels. Organic photovoltaic cells are easy built by deposition techniques like spin coating, moreover PV devices have lower weight, flexible shape and low production cost in comparison with inorganic equivalents . These features have fuelled the interest of both science and industry. The conversion of solar light into electric power requires the generation of both negative and positive charges. The operation of a photovoltaic cell can be generally divided into three basic steps: light absorption, charge separation and charge collection of the appropriate carriers to anode and metallic cathode.When photons are absorbed, only small part of incident light is absorbed because of size of ba[...]
