Owing to our increasing demand for clean and renewable energy, photovoltaics (PV) are emerging as a critical component to the energy equation. However, in order to reduce our dependence on traditional energy sources and expand our solar market, a substantial change in technology is required. The most efficient next-generation photovoltaic cell is the low-cost dye-sensitized solar cell (DSSC). The dye molecule is a key component in the DSSC, and our research looks to design and commercialize new organic dyes and fabrication techniques for DSSC applications. While our program is heavily based on design and synthesis of new dyes, physical characterization cannot be overstated. Spectroelectrochemistry is a technique that examines electron mobility throughout the many interfaces of the photovoltaic circuit. Ultimately, the information garnered from this technique is used to improve device/dye stability and efficiency. In addition to optimizing this future technology, this instrumentation also serves as a platform for training the next generation of highly qualified personal (HQP) capable of advancing our emerging solar industry. This funding for spectroelectrochemical instrumentation will aid in the training of HQP and provide benefit to Canada by advancing low-cost photovoltaic technology.
