Center for Interface Science: Solar ElectricMaterials (CIS:SEM)
Vision:
CIS:HSEM will become a national resource for:i) understanding and controlling the interface science
underlying solar energy conversion technologiesbased on organic and organic-inorganic hybridmaterials;
ii) inspiring, recruiting and training future scientistsand leaders in the basic science of solar electricenergy conversion.
RESEARCH PLAN AND DIRECTIONS
Characterize & control of composition and structure of interfaces betweennanostructured organic semiconductors and oxides or metals. Interfaceslimit the energy conversion efficiencies and scale-up of Generation IIIsolar cells. New materials and characterization methods will enable
scientific understandings that lead to future low-cost solar-electric energyconversion technologies with unprecedented performance .
