Energy Offsets at Donor/Electrode and Acceptor/Electrode Interfaces: Implications for Selective and Efficient Harvest of Charges in Organic Photovoltaic Cells

化学部支持亚利桑那大学的奥尔加·格里菲斯作为美国化学竞争力研究员。 Griffith博士将与Neal Armstrong教授合作，研究模拟太阳能光伏发电中发现的模型材料中的供体电极和受体电极界面。 这项研究将使用各种电子光谱，除了扫描探针显微镜来研究这些系统。 其他工作将与国家可再生能源实验室的科学家大卫金利博士合作进行。 为了扩大参与范围，PI将与图森野猫学校的学生（8-12年级）和教师合作，开发通过能源相关项目教授科学和工程原理的课程材料。 许多学生将来自传统上在科学领域代表性不足的群体。像格里菲斯博士这样的研究旨在更好地理解太阳能转化为有用电力的复杂性。 像这里支持的研究结果将导致更好，更有效的太阳能转换设备。 格里菲斯博士正在努力扩大参与，目的是有效地使各种青年群体参与与重要社会问题有关的科学和工程活动。 这样的活动的希望是鼓励有才华的美国人追求科学和技术事业。

The Division of Chemistry supports Olga Griffith of the University of Arizona as an American Competitiveness in Chemistry Fellow. Dr. Griffith will work with Prof. Neal Armstrong to investigate the donor-electrode and acceptor electrode interfaces in model materials that mimic those found in solar photovoltaics. The research will use a variety of electron spectroscopies, in addition to scanning probe microscopies to study these systems. Additional work will be carried out in collaboration with Dr. David Ginley, a scientist at the National Renewable Energy Laboratory. For her plan for broadening participation, the PI will work with students (8-12 grade) and teachers at the Tucson Wildcat School to develop curricular materials which teach science and engineering principles through energy-related projects. Many of the students served will come from groups that have been traditionally underrepresented in the sciences.Research like that of Dr. Griffith is aimed at developing a better understanding of the intricacies of the conversion of solar energy into useful electrical power. Results from research like that supported here will lead to better, more efficient, devices for the conversion of solar energy. The efforts at broadening participation being pursued by Dr. Griffith are aimed at effectively engaging a diverse group of young people in science and engineering activities that relate to important societal problems. The hope of activities like these is to encourage talented Americans to pursue careers in science and technology.
