The world relies primarily on non-renewable fossil fuels for energy and particularly, the United States alone burns 900 million tons of coal a year. While we consume approximately 13 terawatts of energy globally, the sun continually provides us with 800 terawatts. Using organic photovoltaics to generate electricity from natural light in a cheap manner has the potential to decrease global strife, while fulfilling society’s ever increasing need for energy. To date, several efforts have been made to design and synthesize new photoactive materials in order to optimize the performance of organic solar cells. Herein, we propose the synthesis of an end-cap unit, based on a fullerene derivative, to be incorporated in a block co-polymer. We expect a significant modification in the active layer morphology due to the presence of the acceptor component directly linked to semiconducting polymer. Modification of the active layer structure influences the distribution of the donor and acceptor components, and thus how well electrons propagate through the system. Finally, we are partnering with our materials laboratory to test the performance of our proposed polymer in organic solar cells devices.
