U.S.-Germany Cooperative Research: Preparation of Thin Polycrystalline Silicon Films of High Quality

该奖项支持谢尔盖·奥斯塔彭科博士和南佛罗里达大学的一名研究生与斯图加特大学物理电子系的Jürgen Werner合作。这项合作将德国和美国两个小组的互补能力结合在一起，研究超声波处理对玻璃和多晶硅太阳能电池上热线氢化多晶硅薄膜的影响。多晶硅中的缺陷决定了所形成材料的电子质量，提高材料质量的方法之一是通过氢化来钝化缺陷。除了探索超声波的影响外，这项研究还将应用传统和新的表征技术相结合的方法来监测这些影响。研究将使用两个机构的实验设施，人员和研究生的交流将有力地有利于先进知识和能力的转移。这项研究的结果可能会对用于有源矩阵液晶显示技术的新一代低成本太阳能电池和高性能薄膜晶体管产生影响。

This award supports Dr. Sergei Ostapenko and a graduate student from the University of Southern Florida in a collaboration with J¼rgen Werner of the Department of Physical Electronics at the University of Stuttgart. The collaboration brings together the complementary capabilities of the German and U.S. groups to study the effects of ultrasound treatment on hot-wire hydrogenated polysilicon thin films on glass and polysilicon solar cells. Defects in the polysilicon determine the electronic quality of the material formed, and one way to improve the quality is to passivate the defects by hydrogenation. In addition to exploring the effects of ultrasound, the research will apply a combination of traditional and novel characterization techniques to monitor those effects. The research will use experimental facilities of both institutions, and the exchange of personnel and graduate students will strongly benefit the transfer of advanced knowledge and capabilities. The results of the research could have an impact on a new generation of low-cost solar cells and high-performance thin-film transistors used for active-matrix liquid-crystal-display technology.
