Due to an increase in demand for alternative renewable resources to replace nonrenewable resources, which are negatively impacting the environment, there has been an increase in interest in organic solar cell devices. An alternative to traditional silicon-based solar cells, which have low energy efficiencies and are expensive, is a carbon-based photovoltaic cell that uses fulvene-derivatized fullerenes with favorably low band gaps. Low band gap energies and favorable conductive properties for fullerene-fulvene derivatives have been calculated using a novel DFT method. By utilizing a three-step synthesis and various data analyzation methods, a fulvene-derivatized fullerene are produced for possible application in organic solar cells.
