SEES Fellows: Sustainable organic solar power from printed building-integrated panels

这个跨学科的项目将通过考虑产品的整体生命周期，探索采用可持续印刷有机光伏(OPV)模块用于建筑物集成太阳能生产的技术、环境和社会经济障碍。研究工作将集中在：1)验证在高光伏器件中补偿光电流损失的新策略，2)提供从摇篮到坟墓的印刷OPV模块作为建筑集成屋顶瓦片的评估，3)开发一条从无卤素溶剂获得最先进效率的一般途径，以及4)为一系列新型的同源无富勒烯有机接受者开发电荷产生/复合机理的综合图景。虽然太阳能在技术上具有任何可持续资源中最大的潜力，但目前仅用于供应全球能源需求的约0.1%。实施任何潜在的颠覆性太阳能发电技术的能力，自下而上受到可用材料的性能、可制造性和竞争用途/经济性的限制，从上层受到决策框架(公共/财政政策、个人财务)的限制，其中包括与产品-S从摇篮到坟墓的生命周期有关的决策框架。该项目将探索太阳能发电设备的可持续性，这些设备能够由需要低能量投入和低资本投资的新型有机染料和聚合物(有机光伏或OPV)制造。由于OPV可以相对较轻，可以任意模压到柔性或弯曲的基材上，因此它们有可能集成到屋面瓦片等建筑部件中，从而降低成本。这项研究将评估这种应用的技术、环境和社会经济可行性。该项目还将邀请和指导高中生参加实践学习活动，展示太阳能吸收光并将其转化为电能的基本概念，与广大公众分享研究成果，并将在太阳能开发领域建立大学与行业合作伙伴关系。该项目由美国国家科学基金科学、工程和教育可持续发展研究员(SEE FLOLS)计划支持，目标是帮助实现必要的发现，为导致环境、能源和社会可持续发展的行动提供信息，同时创造必要的劳动力来应对这些挑战。在SEES研究员的支持下，该项目将使有前途的早期职业研究人员能够在与可持续发展相关的独立研究生涯中站稳脚跟。

This interdisciplinary project will explore the technological, environmental, and socioeconomic barriers to adopting sustainably printed organic photovoltaic (OPV) modules for building-integrated solar power production by considering the overall life cycle of the product. Research efforts will focus on: 1) validating a new strategy for recouping photocurrent losses in high photovoltage devices, 2) providing a cradle-to-grave assessment of printed OPV modules as building-integrated roofing shingles, 3) developing a general route to achieving state-of-the-art efficiencies from halogen-free solvents, and 4) developing a comprehensive picture of the charge generation/recombination mechanism for a novel homologous series of fullerene-free organic acceptors.While solar power technically has the greatest potential of any sustainable resource, it is currently used to supply only about one-tenth of one percent of worldwide energy demand. The ability to implement any potentially disruptive technology for solar power generation is constrained from below by the performance, manufacturability, and competing uses/economics of available materials, and constrained from above by decision making frameworks (public/fiscal policy, individual finance) related to, among other things, the product?s cradle-to-grave life cycle. This project will explore the sustainability of solar power devices capable of being fabricated from novel organic dyes and polymers (organic photovoltaics or OPVs) that require low energy inputs and low capital investment. Because OPVs can be relatively lightweight and can be arbitrarily molded to flexible or curved substrates, they have potential for being integrated into building components such as roofing shingles, thus bringing down costs. This research will assess the technological, environmental, and socioeconomic feasibility of such applications.This project will also engage and mentor high school students in hands-on learning activities that demonstrate the basic solar energy concepts of absorbing light and converting it to electricity, will share research results with a broad public audience, and will establish university-industry partnerships in the area of solar energy development.This project is supported under the NSF Science, Engineering and Education for Sustainability Fellows (SEES Fellows) program, with the goal of helping to enable discoveries needed to inform actions that lead to environmental, energy and societal sustainability while creating the necessary workforce to address these challenges. With SEES Fellows support, this project will enable a promising early career researcher to establish themselves in an independent research career related to sustainability.
