Energy sustainability represents one of the grand challenges facing modern society, and solar power provides an important source of renewable energy. Photovoltaics (PV), or solar cells, are solid-state semiconductor-based devices that converts sunlight directly to electricity and do not generate pollution, emissions, or greenhouse gases during operation. The IUCRC for Next Generation Photovoltaics (NGPV or the Center) is one of the world's leading PV research consortia. The NGPV promotes science and advances prosperity and welfare through the Center's successful, ongoing research and education programs. These programs are focused on bringing down PV system cost, increasing PV system efficiency, and enabling widespread the use of PV electricity. The Center's research vision is to make PV electricity a major source of energy. There are currently three research sites in the Center: Colorado State University (CSU), The University of Texas at Austin (UT Austin), and Texas A&M University (TAMU).The CSU site of NGPV is focused on reducing the cost of solar energy through advancing thin film PV device performance, performing state-of-the-art materials characterization, streamlining manufacturing and improving module reliability. The PV-training approach at CSU is strongly team based: students from different disciplines including a significant number of women and veterans work closely with each other, with engineers from industry, and in many cases with students at other universities. Three key PV technologies, developed at CSU, have been translated to industry. A key goal of the CSU site is to continue to advance the state of the art by developing more sophisticated CdTe based device structures with higher efficiencies and improved understanding through advanced materials and electronic characterization. Recently, the CSU site demonstrated device efficiency of 19.2%, the highest efficiency demonstrated for polycrystalline CdTe materials by any academic or national laboratory worldwide. These advances have been demonstrated on pilot scale systems with a direct line of sight to industrial manufacturing. A key research thrust is to demonstrate still higher cell efficiencies, with 25% being a realistic near-term (3 year) goal and 30% the longer term goal. The unique co-sublimation technology developed at CSU will be utilized for the fabrication of the advanced device structures. In addition to improving device efficiencies, research focus at CSU has progressed to improve module efficiency, improve reliability and facilitate deployment. The efforts will lead to lower LCOE (levelized cost of electricity) and help facilitate the goal of 2-3 cents/kWhr. Overall, center has the potential to further increase the impact of the multi-billion-dollar U.S. PV industry that is growing rapidly and greatly expand the application of solar electricity.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

能源可持续性是现代社会面临的重大挑战之一，而太阳能是可再生能源的重要来源。光伏 (PV) 或太阳能电池是基于固态半导体的设备，可将阳光直接转化为电能，并且在运行过程中不会产生污染、排放或温室气体。 IUCRC 下一代光伏发电（NGPV 或中心）是世界领先的光伏研究联盟之一。 NGPV 通过该中心成功、持续的研究和教育项目来促进科学并促进繁荣和福利。这些计划的重点是降低光伏系统成本、提高光伏系统效率并实现光伏电力的广泛使用。该中心的研究愿景是使光伏发电成为主要能源。该中心目前拥有三个研究站点：科罗拉多州立大学（CSU）、德克萨斯大学奥斯汀分校（UT Austin）和德克萨斯农工大学（TAMU）。NGPV CSU站点专注于降低太阳能成本通过提高薄膜光伏器件性能、执行最先进的材料表征、简化制造和提高模块可靠性。 科罗拉多州立大学的光伏培训方法以团队为基础：来自不同学科的学生（包括大量女性和退伍军人）彼此密切合作，与来自行业的工程师密切合作，在许多情况下与其他大学的学生密切合作。科罗拉多州立大学开发的三项关键光伏技术已转化为产业。 CSU 基地的一个关键目标是通过开发更复杂的基于 CdTe 的器件结构，提高效率并通过先进材料和电子表征加深理解，从而继续推进最先进的技术。 最近，科罗拉多州立大学现场展示了 19.2% 的器件效率，这是全球学术或国家实验室证明的多晶 CdTe 材料的最高效率。这些进步已经在直接观察工业制造的中试规模系统上得到了证明。一个关键的研究重点是证明更高的电池效率，25% 是一个现实的近期（3 年）目标，30% 是长期目标。科罗拉多州立大学开发的独特共升华技术将用于制造先进的器件结构。除了提高设备效率外，科罗拉多州立大学的研究重点还致力于提高模块效率、提高可靠性和促进部署。这些努力将降低 LCOE（平准化电力成本），并有助于实现 2-3 美分/kWhr 的目标。总体而言，该中心有潜力进一步提高快速增长的数十亿美元的美国光伏产业的影响力，并极大地扩大太阳能发电的应用。该奖项体现了 NSF 的法定使命，经评估认为值得支持。基金会的智力价值和更广泛的影响审查标准。
