    In these times of diminishing reserve of fossil fuel, the development of novel - green or renewable? technologies to meet the increasing worldwide demand for energy is of great importance. The sun is the largest carbon free source of energy and an infinite source of renewable energy. However, except for the expensive inorganic crystalline silicon photovoltaic cells, this source of energy has not been utilized. The field of organic photovoltaic cell has made impressive progress in the last few years with the tremendous efforts of researchers working tirelessly to develop organic materials for solar energy conversion. Organic conjugated materials have the advantage of low cost, light weight, process-ability and good flexibility over inorganic materials. They have attracted wide academic and industrial interest due to their promise as semiconductors for photovoltaic applications. Design of advanced organic conjugated materials with the ability to absorb light from the sun and convert it into useful and storable form has and still is one of the most important goals of researchers in the field of renewable energy. This work describes a number of novel exciting and promising materials based on polycyclic aromatic compounds (PACs) for organic photovoltaic cells and organic light emitting diodes.
