项目摘要

This MRI project has two main aims. The first is to advance knowledge toward the production of low-cost, high-efficiency solar cell technologies that can produce renewable energy with minimal environmental impact. Such devices convert light into electricity and are the most promising solution for providing clean energy for the future of humanity. The second is to enable training of the next generation of science and engineering experts for careers in public service and private industry. Pomona and Harvey Mudd Colleges will obtain and maintain an integrated tool set for photovoltaic research. This will enable a team of faculty and student researchers at the Claremont Colleges to efficiently build and test next-generation solar cells. The three lead faculty each have long-standing, productive research programs with high-impact journal articles and technical reports in interlocking areas of photovoltaic research. This project will enhance their local and external collaborations and accelerate their studies. Harvey Mudd and Pomona rank highly among U.S. colleges in their proportion of graduates who later earn graduate degrees in science and engineering, including many from underrepresented groups. For example, more than 70% of the PI's research students in the past 5 years have been students from underrepresented groups in STEM. Each investigator is actively developing community outreach programs with K-12 students. Efficiency of new solar cell technologies is approaching that of conventional solar cells. While the cost of conventional cells has fallen sharply, high temperature vacuum processes on glass plates are inherently more expensive than printing processes typical in new solar cells. In competing with existing solar cell technologies there are three key areas for new solar cells: efficiency, cost, and lifetime. Cell lifetime and failure mechanisms are accordingly a major focus of ongoing research. Such studies will be advanced by the acquisition and installation of a integrated tool set for photovoltaic research. Professors Hudgings and Tanenbaum conduct research on defects and degradation in various types of solar cells, including organic solar cells using electrical measurements, spatially resolved optical probing techniques, and lifetime studies both under lamps and true solar illumination on a rooftop solar tracking platform. Dr. Tanenbaum is now fabricating and characterizing perovskite solar cells including those made with mesoporous templates, similar to dye-sensitized solar cells. Dr. Van Ryswyk focuses on optimizing absorption and charge extraction techniques in dye-sensitized and quantum dot-based inverted bulk heterojunction cells. While each research group has independent projects, they hold joint meetings to discuss their research problems, methods, and results. The Claremont Colleges have a long history of successful research collaboration and shared facilities, such as a shared microscopy facility used by researchers across all five colleges, including these PIs and more than 150 others, mostly advanced undergraduates.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.

这个MRI项目有两个主要目标。第一个目标是促进低成本、高效率太阳能电池技术的生产，这种技术可以生产可再生能源，对环境的影响最小。这些设备将光转化为电，是为人类未来提供清洁能源的最有前途的解决方案。第二个目标是为公共服务和私营企业培养下一代科学和工程专家。Pomona和Harvey Mudd学院将获得并维护光伏研究的集成工具集。这将使克莱蒙学院的教师和学生研究人员团队能够有效地构建和测试下一代太阳能电池。这三个主要的教师都有长期的，富有成效的研究计划，具有高影响力的期刊文章和技术报告，在光伏研究的联锁领域。该项目将加强他们的本地和外部合作，并加快他们的研究。Harvey Mudd和Pomona在美国大学中的毕业生比例很高，他们后来获得了科学和工程研究生学位，其中包括许多来自代表性不足的群体。例如，在过去5年中，PI的研究生中有70%以上是来自STEM代表性不足群体的学生。每个调查员都积极与K-12学生开展社区外展计划。新的太阳能电池技术的效率正在接近传统太阳能电池的效率。虽然传统电池的成本已经大幅下降，但玻璃板上的高温真空工艺本质上比新型太阳能电池中典型的印刷工艺更昂贵。在与现有太阳能电池技术的竞争中，新太阳能电池有三个关键领域：效率，成本和寿命。因此，电池寿命和失效机制是正在进行的研究的主要焦点。将通过购置和安装一套光伏研究综合工具来推进这些研究。Hudgings和Tanenbaum教授对各种类型的太阳能电池的缺陷和退化进行研究，包括使用电气测量，空间分辨光学探测技术的有机太阳能电池，以及在屋顶太阳能跟踪平台上的灯和真实太阳照明下的寿命研究。Tanenbaum博士现在正在制造和表征钙钛矿太阳能电池，包括那些用中孔模板制成的电池，类似于染料敏化太阳能电池。货车Ryswyk博士专注于优化染料敏化和基于量子点的倒置体异质结电池中的吸收和电荷提取技术。虽然每个研究小组都有独立的项目，但他们举行联席会议，讨论他们的研究问题，方法和结果。克莱蒙学院在成功的研究合作和共享设施方面有着悠久的历史，例如所有五所学院的研究人员（包括这些PI和其他150多名研究人员，其中大多数是高年级本科生）都使用共享的显微镜设施。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
