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.

能源可持续性代表了现代社会面临的巨大挑战之一，太阳能提供了可再生能源的重要来源。光伏（PV）或太阳能电池是固态半导体的设备，可将阳光直接转换为电能，并且在操作过程中不会产生污染，排放或温室气体。 下一代光伏的IUCRC（NGPV或中心）是世界领先的PV研究联盟之一。 NGPV通过该中心的成功，正在进行的研究和教育计划来促进科学和进步繁荣和福利。这些程序的重点是降低光伏系统成本，提高光伏系统效率，并可以广泛使用PV电力。该中心的研究愿景是使光伏电力成为主要能源。该中心目前有三个研究站点：科罗拉多州立大学（CSU），德克萨斯大学奥斯汀大学（Austin）和德克萨斯A＆M大学（TAMU）。NGPV的CSU站点专注于通过降低太阳能成本，通过推进薄膜PV设备的性能，进行整体材料的制造，并改进了制造材料，并改进了制造的制造，并改进了制造的制造，并改进了材料的成本。 CSU的PV培训方法是基于团队的：来自不同学科的学生，包括大量妇女和退伍军人与彼此紧密合作，工程师的工程师，在许多情况下与其他大学的学生一起。在CSU开发的三种主要的PV技术已转化为行业。 CSU站点的一个关键目标是通过开发更复杂的基于CDTE的设备结构，并通过高级材料和电子表征来改善理解。 最近，CSU站点的设备效率为19.2％，这是全球任何学术或国家实验室对多晶CDTE材料证明的最高效率。这些进步已在飞行员量表系统上展示出来，该系统直接对工业制造业有直接的视线。一个关键的研究作用是证明细胞效率仍然更高，其中25％是一个现实的近期（3年），而长期目标是30％。 CSU开发的独特共同宣传技术将用于制造高级设备结构。除了提高设备效率外，CSU的研究重点还在提高模块效率，提高可靠性和促进部署方面的进步。这些努力将导致LCOE降低（电力水平），并有助于促进2-3美分/千瓦的目标。总体而言，中心有可能进一步增加数十亿美元的美国光伏行业的影响，该行业正在迅速增长，并大大扩展了太阳能的应用。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响标准通过评估来评估的。
