Boosting SUstaiNability, Reliability and EfficiencY of perovskite PV through novel materials and process engineering.

钙钛矿型光伏电池在过去十年中取得了快速发展，有望实现更高的能效，减少嵌入能量和二氧化碳排放，为柔性光伏等多种应用提供低温生产，所有这些都可能比目前的硅技术低得多的成本。然而，较差的稳定性和较短的使用寿命阻碍了钙钛矿型光伏电池的广泛应用。目前性能最好的材料也含有铅，这是有毒的，对健康和环境有害。为了解决这些限制因素，SUNREY将通过涵盖设备设计和制造的所有方面的一系列创新来解决这些限制因素的根本原因，包括改善钙钛矿材料本身的稳定性/性能比、开发新的电荷传输和电极材料以及可配置到不同钙钛矿型吸收材料的低成本沉积方法、开发稳定性更高的无铅材料、开发一系列从层到模块的阻挡和封装措施以及工艺优化。这些技术发展将得到退化机理分析的新方法的支持，并纳入模型以将阻挡层性能数据与器件性能模型和测试数据相结合。设计过程将由生命周期、循环性和可持续性分析驱动。开发将通过认证实验室在实际实验室条件下和室外的测试来验证TRL5。与硅相比，SUNREY的目标是将高效率(25%基于铅，15%无铅)与长寿命(25年)、减少排放和制造成本的突破性结合在一起。这将为财团公司带来广泛的新机会，包括公用事业规模的电池板、物联网和微型电源、独立电源、建筑应用公用事业电力(BAPV)建筑-集成光伏。

Perovskite photovoltaics have seen rapid advances in the last decade with the promise of higher efficiency, reduced embedded energy and CO2 emissions, low-temperature production for versatile applications such as flexible photovoltaics and all at potentially much lower cost than current Si technology. However, poor stability and short lifetime in the field is holding back wide deployment of perovskite photovoltaics. The current best performing materials also contain lead (Pb) which is toxic and damaging to health and the environment. To address these limitations, SUNREY will tackle the root causes of these limiting factors through a suite of innovations covering all aspects of the device design and manufacture including improvements to the stability/performance ratio of the perovskite materials themselves, development of new charge transport and electrode materials and low-cost deposition methods that can be configured to different perovskite absorbers, development of improved stability Pb-free materials, development of a range of measures for barriers and encapsulation from layers to module and process optimisation. These technology developments will be underpinned by new approaches to degradation mechanism analysis and the incorporation of modelling to combine barrier properties data with device performance models and test data. The design process will be driven by lifecycle, circularity and sustainability analyses. Developments will be validated to TRL5 through testing by an accredited laboratory under both realistic laboratory conditions and outdoors. SUNREY targets a breakthrough combination of high efficiency (25% Pb-based, 15% Pb-free) with long lifetime (25 years), reduced emissions and cost of manufacturing compared to Si. This will open up a wide range of new opportunities for the consortium companies including utility-scale panels, IoT and MicroPower, Independent Power Sources, Building Applied Utility Power (BAPV) Building-Integrated Photovoltaics.
