Bulk heterojunction solar cells offer numerous potential advantages over inorganic photovoltaic devices. However, the materials used in these organic solar cells need higher efficiencies to allow organic devices to become more effective. A variety of small molecules were selected for synthesis based on their potential electrochemical properties for use in organic photovoltaic devices. These highly conjugated molecules will provide an ordered domain to allow for the transportation of charge carriers throughout the cell. Synthetic routes for the fabrication of these molecules were determined and performed, followed by their purification and characterization. Further analysis of these small molecules will be performed in addition to their electropolymerization. Ultimately, these new materials will be tested within photovoltaic devices to determine their effects on organic solar cell efficiency.
