Photovoltaic Behavior

A series of symmetrically substituted subphthalocyanine derivatives with diverse substituent such as electron-donating or electron-withdrawing moieties at the peripheral position have been synthesized and their photophysical and electrochemical properties have been investigated. Solution-processed bulk heterojunction (BHJ) organic solar cells using SubPc derivatives as electron donor and fullerene derivative PCBM as an electron acceptor in the active layer were fabricated and characterized to evaluate the photovoltaic behavior of these molecules.
