Recently, much effort has been expended to convert solar energy effectively to electric energy by organic solar cells. Although inorganic solar cells have been the primary focus, due to the abundance of organic materials having a variety of absorptions, a large number of organic solar cell have been studied today. The need to develop inexpensive renewable energy sources has continued to stimulate new approaches to production of efficiency low-cost organic solar cell device. In organic solar cells, semiconductor particles and an electron acceptor or an electron donor are blended together to create a heterogeneous material that functions as a portion of the device. This work focuses on photovoltaic and optical properties of organic solar cell devices used porphyrin derivative or porphyrin derivative/fullerene derivative as an active layer. We have fabricated two kinds of the organic solar cells based on porphyrin derivative and porphyrin derivative/fullerene derivative to compare the photovoltaic effect as active layer in organic solar cell. |
