Organic photovoltaics (OPVs) hold the promise of delivering efficient low-cost, lightweight, flexible, and portable solar cells. Driven by this promise, the last decade has witnessed an explosive growth in this area resulting in dramatic increases in power conversion efficiencies (PCEs). Yet the challenge framed in the 2005 Basic Energy Sciences Advisory Committee report “Basic Energy Needs for Solar Energy Utilization” still remains, that there is a “…huge gap between present uses of solar energy and the remaining, enormously undeveloped potential…”.

The primary research aim of the PHaSE EFRC is to advance the state of the art in organic solar energy performance using new syntheses for the design and implementation of OPV photoactive layer morphologies and interfaces. This requires quantitative probing and understanding of morphology and structure-property relationships that enhance solar conversion efficiency, including in situ probes of "as-fabricated" morphologies in OPV devices. The PHaSE EFRC provides a coordinated, multi-investigator, cross-disciplinary program for continuous collaboration and synergistic interaction between researchers at every stage of OPV component design, evaluation and assembly.
