NEXt generation of sUstainable perovskite-Silicon tandem cells

NEXUS将通过开发钙钛矿-硅串联光催化剂来加速欧洲向清洁能源的过渡，通过一种新的欧洲范式：基于效率，成本，可持续性，循环性和社会方面的全球生态设计方法，在整个价值链中使用丰富的材料。我们的创新将提高每个地区的光伏发电量，使用可持续，一致和有竞争力的欧洲光伏生产，保证清洁能源转型，并确保安全和负担得起的欧盟能源供应。NEXUS将开发稳定的双端钙钛矿-硅叠层太阳能电池，其功率转换效率>33%（组件>30%），稳定性与最先进的单结硅光伏组件相似。我们将采用创新的生态设计方法来开发这些具有挑战性的目标：采用无溶剂钙钛矿沉积，循环性，可回收性，改进的简单制造工艺，为这种可持续技术的欧洲商业化创造可行的经济途径。这些进展是基于开发高性能、无溶剂、钙钛矿顶部吸收剂、基于地球丰富材料的导电氧化物用于不同应用以及实施生态设计标准以开发底部PV-Si电池，从而减少其CO2足迹。因此，我们将实现具有210 kWh/m2的最大功率输出的钙钛矿-Si电池和模块。我们将提高新型硅技术的耐用性和可持续性，同时开发新方法，以提供对环境压力因素具有前所未有的弹性的极高电压钙钛矿太阳能电池。我们将展示每个步骤的可扩展性和概念验证设备集。NEXUS是一个多学科联盟：来自9个欧洲国家的12个合作伙伴; 5个工业合作伙伴（2个中小企业）和7个研究和技术组织，涵盖从研究中心到技术提供商，最终用户和市场的整个创新价值链。

NEXUS will accelerate Europe’s transition to clean energy by development of perovskite-Si tandem photovoltaics, via a new European paradigm: a global eco-design approach based on efficiency, cost, sustainability, circularity and social aspects, using abundant materials in the whole value chain. Our innovations will improve the PV Energy Yield per area, using sustainable, coherent and competitive European PV production, guaranteeing a clean energy transition and ensuring a secure and affordable EU energy supply. NEXUS will develop stable, 2-terminal perovskite-Si tandem solar cells with power conversion efficiencies >33% (modules >30%) and stabilities like state of the art single junction Silicon PV modules. We will develop these challenging targets following an innovative eco-design approach: employing solvent-free perovskite deposition, circularity, recyclability, improved simple manufacturing processes, to create a viable economic pathway for the European commercialization of this sustainable technology. Advances are based on development of high performance, solvent-free, perovskite top absorbers, of conductive oxides based on earth abundant materials for different applications and the implementation of eco-design criteria for development of the bottom PV-Si cell, reducing its CO2 footprint. Thus we will achieve perovskite-Si cells and modules with a maximized power output of 210 kWh/m2. We will increase durability and sustainability in a novel silicon technology, while developing new approaches to deliver very high voltage perovskite solar cells with unprecedented resilience to environmental stress factors. We will demonstrate scalability and proof-of-concept equipment set for each step. NEXUS is a multi disciplinary consortium: 12 partners from 9 European countries; 5 industrial partners (2 SMEs) & 7 Research & Technology organizations, covering the whole value chain of innovation from research centers to technology providers, end-users and market and policies.
