SolMates aims to provide a novel industrial, scalable technology for producing flexible, durable, made-to-measure, two-terminal CIGSe/ perovskite multijunction thin-film PV modules. By optimized matching of narrow bandgap CIGS bottom cells on flexible substrates (steel, polyimide and flexible glass) with high bandgap perovskite top cells, a conversion efficiency higher than 30% (1cm²) will be reached. The focus on roll-to-roll compatible large-area high-rate deposition techniques for both layer systems in combination with the development of in-line quality control units for defect detection will lead to a minimized cell-to-module gap and full industrial scale-up after the project ends. SolMates will demonstrate a 100 cm² flexible, lightweight, durable, encapsulated monolithic interconnected tandem thin-film module with more than 25%. Due to a unique serial interconnection the made-to-measure production of highly-efficient PV modules in respect to shape, size and output voltage based on multijunction solar cells will become a reality. The developed technologies boost the power output of flexible thin-film PV, paving the way for the uptake of long awaited applications such as integrated PV. By exploiting already existing surfaces for solar energy generation, land-use conflicts will be minimized and the total costs for PV can be reduced. The involved, innovation driven SMEs will cooperate with the research partners to facilitate a pathway to mass production, low-cost, roll-to-roll fabrication of SoleMates’ PV technology and strenghten the EU PV value chain. The environmental footprint of the technology, which is inherently low for thin film devices with thin, flexible, lightweight substrates and encapsulation, will be carefully assessed with respect to SolMates' recycling strategy. Possible end-use applications will be reviewed and a long-term vision, focusing on the environmental, social and economic benefits of utilising PV in our daily lives will be developed.

SolMates旨在提供一种新型的工业化可扩展技术，用于生产灵活，耐用，量身定制的双端CIGSe/钙钛矿多结薄膜光伏组件。通过将柔性基板（钢、聚酰亚胺和柔性玻璃）上的窄带隙CIGS底部电池与高带隙钙钛矿顶部电池进行优化匹配，将达到高于30%（1cm²）的转换效率。专注于两种层系统的卷对卷兼容大面积高速沉积技术，结合用于缺陷检测的在线质量控制单元的开发，将在项目结束后最大限度地减少电池到模块的间隙和全面的工业规模。SolMates将展示一款100 cm²的柔性、轻质、耐用、封装的单片互连串联薄膜模块，其集成度超过25%。由于独特的串联互连，基于多结太阳能电池的形状、尺寸和输出电压的高效光伏组件的定制生产将成为现实。所开发的技术提高了柔性薄膜光伏的功率输出，为集成光伏等期待已久的应用铺平了道路。通过利用现有的表面进行太阳能发电，土地使用冲突将最小化，光伏发电的总成本也将降低。参与的创新驱动型中小企业将与研究合作伙伴合作，促进SoleMates光伏技术的大规模生产，低成本，卷对卷制造，并加强欧盟光伏价值链。该技术的环境足迹对于具有薄、柔性、轻质基板和封装的薄膜器件来说本来就很低，将根据SolMates的回收策略进行仔细评估。我们将检讨可能的最终用途应用，并制定长远愿景，重点关注在日常生活中使用光伏发电的环境、社会及经济效益。
