The PHaSE energy center carries out fundamental photovoltaic-oriented research using organic-based polymers and related materials to maximize efficiency in the collection and harvesting of energy over a broad frequency range of the solar spectrum. The center’s strongly-networked, interdisciplinary teams of researchers seek ways to minimize charge-quenching exciton recombination, to maximize electron transport across inorganic/organic interfaces, and to optimize design and fabrication strategies for making inexpensive photovoltaic devices.
