Since solar energy will never run out and harm the environment, the generation of electricity from solar energy is an ideal renewable energy source. During the last half-century numerous scientists have studied solar cells. By virtue of their tremendous efforts, the power conversion efficiency (PCE) of solar cells has significantly improved. In this dissertation, an overview of solar cell technology will be addressed in terms of materials development, device physics and engineering.application/pdfen-USCopyright is held by the individual authors.crosslinking; dielectric constant; doping; polymer; semiconductor; solar cellMaterials ScienceEngineeringmaterials science and engineeringThesis
