Alternating Polyfluorene Green-6 & (Pcbm) Based Solar Cell: Organic Solar Cell Tesfaye Mamuye Mulatu

Conjugated polymers have attracted considerable attention since they are potential candidates for various opto-electronic device such as solar cells, light emitting diodes, photodiodes, and transisters. Electronic devices based on conjugated polymers can easily processed at low temperature using cheap technologies. This leads to cost reduction, a key deriving force for chosing conjugated polymers for various type of applications. However, fabrication of inorganic semiconductor based solar cells needs expensive technology for purification. As a reault inorganic semiconductor baded solar cells are quite expensive and hardly compute with other existing energy sources. Therefore, to ensure a sustainable technology for solar cells, the development of new materials and devices structures are required. In particular, solar cells based on conjugated polymers are of special interst due to the fact that they can play a major role in generating clean and cheap energy in the future.
