Photovoltaic energy conversion is an important industry for the future of the world?s energy system. The current production volume worldwide is over 2.5 GW/year, growing at over 40% per year. The current industry is based approximately 91% on the use of crystalline Si, and the growth of the industry has been hampered by the high and increasing cost of Si wafers. Intellectual Merit: This GOALI program focuses on developing low cost, high performance solar photovoltaic technology based on thin film Si deposited on polymer substrates, using a transformative device architecture. This proposal addresses an alternative thin film silicon technology that can achieve a level of performance similar to that of thick crystalline silicon , while using only 1-2 micrometer thicknesses. The proposed work focuses on the investigation of novel device architectures including use of amorphous/crystalline superlattices, photonic bandgap structures and new material growth techniques to achieve higher performance in thin film silicon. Broader Impact: The program involves a strong collaboration with PowerFilm Solar, the leading U. S. company working on polymer based solar cells. The program will offer research and educational opportunities to both graduate and undergraduate students.

光伏能源转换是未来世界的重要产业？的能源系统。目前全球的产量超过2.5GW/年，每年增长超过40%。目前的工业大约91%是基于晶体硅的使用，硅晶片的高成本和不断增长的成本阻碍了工业的发展。 智力优势：该GOALI计划的重点是开发低成本，高性能的太阳能光伏技术的基础上，薄膜硅沉积在聚合物基板上，使用变革性的设备架构。该提议提出了一种替代的薄膜硅技术，该技术可以实现与厚晶体硅类似的性能水平，同时仅使用1-2微米的厚度。拟议的工作重点是研究新的器件架构，包括使用非晶/晶体超晶格，光子带隙结构和新的材料生长技术，以实现更高的性能在薄膜硅。 更广泛的影响：该计划涉及到与美国领先的太阳能公司PowerFilm Solar的密切合作。S.公司致力于聚合物基太阳能电池。该计划将为研究生和本科生提供研究和教育机会。
