U.S.-India Cooperative Research: Photoinduced Degradation in Doped Hydrogenated Amorphous Silicon, Award in US and Indian Currency

9634604泰勒描述：拟议的研究“掺杂氢化非晶硅的光诱导降解”是犹他大学的克雷格·泰勒教授与德里大学的P.C.马图尔和R.M.马赫拉教授在材料研究方面的合作。这项提议为泰勒教授对无序半导体和薄膜光伏材料性质的研究增加了一个国际组成部分。泰勒在理解金属硫化物玻璃作为连接四面体配位非晶态材料和传统硫化物玻璃的模型体系方面取得了重大进展。作为合乎逻辑的延伸，这项提议将集中在n型掺杂硅硫合金的光诱导退化和输运性质上。范围：这是一项新的合作，将美国和印度的两所大学研究实验室连接起来。这项研究试图了解a-Si：H中的亚稳态缺陷，这些缺陷对太阳能电池的最佳性能至关重要。这项研究结合了美国在增长、光学和磁共振表征方面的专业知识，以及印度在运输和结构测量方面的专业知识。该研究计划旨在最终提高薄膜晶体管和太阳能电池等设备的稳定性。***

9634604 Taylor Description: The proposed research "Photoinduced Degradation in Doped Hydrogenated Amorphous Silicon (a-SiLH)" is a collaboration in materials research between Professor Craig Taylor, University of Utah and Professors P.C. Mathur and R.M. Mahra, University of Delhi. This proposal adds an international component to Professor Taylor's research on the properties of disordered semiconductors and thin-film photovaltaic materials. Taylor has made significant progress in understanding metal chalcogenide glasses as a model system linking tetrahedrally-coordinated amorphous materials and traditional chalcogenide glasses. As a logical extension, this proposal will concentrate on photo-induced degradation and transport properties of n-type doped silicon- sulfur alloys. Scope: This is a new collaboration linking two university research laboratories in the US and India. The research seeks to understand metastable defects in a-Si:H that are crucial for optimum performance of solar cells. The research combines US expertise on growth, optical and magnetic resonance characterization and Indian expertise on transport and structural measurements. The research plan is designed to make progress on ultimately improving the stability of devices such as thin-film transistors and solar cells. ***
