Polythiophene/Silver (PT/Ag) nanocomposite has been synthesized and characterized. Morphological studies have been made to elucidate the structure of the formed nanocomposite. The morphological studies revealed that the formed nancomposite is highly dendritic forming tree like structure. A bulk heterojunction solar cell (BHJSC) has been built using the prepared nanocomposite as photo active layer....
