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.

化学部支持亚利桑那大学的Olga Griffith成为美国化学竞争力研究员。格里菲斯博士将与尼尔·阿姆斯特朗教授合作，研究模拟太阳能光伏材料的模型材料中的供体电极和受体电极界面。除了扫描探针显微镜外，这项研究还将使用各种电子光谱来研究这些系统。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。对于她扩大参与的计划，PI将与图森野猫学校(Tucson Wildcat School)的学生(8-12年级)和教师合作，开发通过与能源相关的项目教授科学和工程原理的课程材料。许多接受服务的学生将来自传统上在科学界代表性不足的群体。像格里菲斯博士这样的研究旨在更好地理解将太阳能转化为有用电力的复杂性。像这里支持的那样的研究结果将导致更好、更高效的太阳能转换设备。格里菲斯博士正在进行的扩大参与的努力，目的是让不同的青年群体有效地参与与重大社会问题有关的科学和工程活动。像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职业。
