The synthesis and characterization of new boron subphthalocyanine derivatives for organic solar cells

Small molecules with conducting electronic properties resembling those of metals have been used in next generation electronic devices such as organic solar cells. These organic or carbon-based molecules are paving a new road towards environmentally-friendly, flexible and cheaper solar cells. Boron subphthalocyanines (BsubPcs) are an example of small organic molecules that have been used to achieve impressive power conversion efficiencies in these devices. BsubPcs have robust, industrially relevant chemistry and can be chemically modified to predictably tune their physical and electronic properties. In order to assess the structure-property relationships of newly functionalized BsubPcs as well as their impact on solar cell performance, we have expanded the matrix of potential BsubPcs with various halogens (for example, fluorine atoms) in the periphery and carbon-based groups bonded to the central boron atom of the BsubPc.
