This PFI: AIR Research Alliance project focuses on the translation and transfer of higher efficiency Cadmium Telluride (CdTe) photovoltaic (PV) technologies that are derived from the expertise and discoveries in advanced materials processing and devices from the Next Generation Photovoltaics Center (NGPV), a NSF funded Industry and University Co-Operative Research Center. CdTe PV is currently competitive for generating electricity in many parts of the world (e.g. 7-9 cents/kWhr from utility scale projects without subsidy) and the costs are decreasing rapidly. However, the objective of this work is to advance the CdTe technology to the point where solar is a competitive source of energy in all regions for individual home owners and a variety of applications which are now considered too expensive to be done electrically. To achieve this, the work proposed under this award will enable a significant increase in device efficiency while also addressing manufacturing methods to reduce costs. This could have a direct impact on further developing the U.S. based CdTe industry with the potential for significant economic growth and job creation. In addition, results from this research will lead to cost-effective opportunities to displace greenhouse-gas emitting technologies with PV technology and corresponding benefits to the environment. The innovation ecosystem that will be enhanced includes all the leading groups in CdTe PV technology space. The proposed project will be led by Colorado State University (CSU), which has a long history of successful CdTe PV research and is a founding member of the NGPV. The primary research partner and third-party investor will be First Solar, Inc., the largest U.S. manufacturer of solar panels. CSU will also be joined by the Center for Renewable Energy Systems at Loughborough university in UK (CREST), the U.S. National Renewable Energy Laboratory (NREL), and material supplier 5N Plus. Students will gain entrepreneurial and technology translation experience through working with industry on their research projects and formal student training in innovation, entrepreneurship, and technology transfer. This project addresses the following technology gaps as it translates from research discovery toward commercial application. The project will advance CSU's state-of-the-art deposition systems and pursue two separate routes to higher-efficiency manufacturing-friendly cells. The first route will be to advance the research on unique device structures to move them to commercialization, and the second will be to develop PV devices with a higher bandgap suitable for multi-junction cells. In addition, detailed characterization of these advanced devices will be performed. The proposed effort will have a clear line of sight to mass production and has the potential to significantly increase the efficiency of both single-junction and multi-junction CdTe-based solar cells.

这个PFI: AIR研究联盟项目的重点是转化和转移效率更高的碲化镉（CdTe）光伏（PV）技术，这些技术来源于下一代光伏中心（NGPV）在先进材料加工和设备方面的专业知识和发现，NGPV是一个由美国国家科学基金会资助的工业和大学合作研究中心。CdTe光伏目前在世界许多地方的发电方面具有竞争力（例如，在没有补贴的情况下，公用事业规模的项目每千瓦时7-9美分），而且成本正在迅速下降。然而，这项工作的目标是推进碲化镉技术，使太阳能成为所有地区的个人家庭和各种应用的有竞争力的能源来源，这些应用现在被认为过于昂贵而无法用电完成。为了实现这一目标，根据该合同提出的工作将显著提高设备效率，同时解决制造方法以降低成本。这可能会对美国CdTe产业的进一步发展产生直接影响，并具有显著的经济增长和创造就业机会的潜力。此外，这项研究的结果将带来具有成本效益的机会，用光伏技术取代温室气体排放技术，并对环境产生相应的效益。创新生态系统将得到加强，包括CdTe光伏技术领域的所有领先集团。该项目将由科罗拉多州立大学（CSU）领导，该大学在CdTe光伏研究方面有着悠久的成功历史，并且是NGPV的创始成员之一。主要研究合作伙伴和第三方投资者将是美国最大的太阳能电池板制造商First Solar， Inc.。科罗拉多州立大学还将与英国拉夫堡大学可再生能源系统中心（CREST）、美国国家可再生能源实验室（NREL）和材料供应商5N Plus合作。学生将通过与行业合作研究项目和在创新、创业和技术转移方面的正式学生培训，获得创业和技术翻译经验。该项目解决了以下技术差距，因为它从研究发现转化为商业应用。该项目将推进CSU最先进的沉积系统，并追求两条独立的路线，以实现更高效率的制造友好型电池。第一条路线是推进独特器件结构的研究，将其推向商业化，第二条路线是开发适合多结电池的具有更高带隙的光伏器件。此外，还将对这些先进器件进行详细的表征。这项提议的努力将为大规模生产提供清晰的思路，并有可能显著提高单结和多结cdte太阳能电池的效率。
