项目摘要
EPAS: Hierarchical Characterization of Optoelectronic Hyperdoped Silicon Devices for Terawatt-Scale PhotovoltaicsResearch Objectives and Approaches: The objective of this research is to demonstrate a viable route to production of high-performance hyperdoped silicon photovoltaics (PV). The approach is to determine the fundamental properties of performance-limiting defects in PV devices containing hyperdoped silicon, thus leading to fabrication of next-generation devices. Specifically, we will diagnose the current state-of-the-art devices (demonstrate efficiencies of ~1%) using a hierarchical characterization approach, while creating cost-effective devices with drastically improved performance.Intellectual Merit: Hyperdoped materials were discovered 10 years ago and have since drawn interest for their potential photovoltaic applications; yet no significant photovoltaic technology has yet emerged due to a lack of understanding of limiting defects. First, we will carefully characterize and model solar cells fabricated using current hyperdoping methods. Second, we will analyze the fundamental properties of performance-limiting defects, while developing a strategy for how to reduce or eliminate their impact. Lastly, we will fabricate new prototype cells that avoid these pitfalls.Broader Impact: Because it is abundant enough to contribute at the terawatt scale, silicon-based PV is excellently positioned to contribute to the dual goals of decreasing our economy's carbon-intensity while improving energy security. The proposed work will also address the NSF?s mission of advancing discovery while promoting teaching, training, learning, and diversity. Using new media including YouTube and Wikipedia, the group will successfully disseminate the impact of the work to the general public.
EPAS:用于太瓦级光伏的光电超掺杂硅器件的分级表征研究目标和方法:本研究的目的是展示一条生产高性能超掺杂硅光伏(PV)的可行途径。该方法是确定包含超掺杂硅的光伏器件中性能限制缺陷的基本特性,从而导致下一代器件的制造。具体地说,我们将使用分级表征方法来诊断当前最先进的器件(展示~1%的效率),同时创造性能大幅提高的成本效益器件。智力优势:超掺杂材料在10年前被发现,自那以后吸引了人们对其潜在的光伏应用的兴趣;然而,由于缺乏对限制缺陷的了解,尚未出现重大的光伏技术。首先,我们将仔细地对使用当前超掺杂方法制造的太阳能电池进行表征和建模。其次,我们将分析性能限制缺陷的基本属性,同时制定如何减少或消除其影响的策略。最后,我们将制造避免这些缺陷的新原型电池。更广泛的影响:由于硅基光伏的储量足够大,可以做出太瓦级的贡献,因此它处于有利地位,可以为降低我们经济的碳强度和改善能源安全的双重目标做出贡献。拟议的工作还将涉及美国国家科学基金会S的使命,即在促进教学、培训、学习和多样性的同时推进发现。利用YouTube和维基百科等新媒体,该组织将成功地将这项工作的影响传播给普通公众。
