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

在过去的十年中，Percent photopolymics取得了快速的发展，有望提高效率，减少嵌入式能源和二氧化碳排放，低温生产用于灵活的photopolymics等多用途应用，并且所有这些都可能比当前的Si技术成本低得多。然而，在该领域中稳定性差和寿命短阻碍了钙钛矿光致发光材料的广泛应用。目前性能最好的材料还含有铅（Pb），铅是有毒的，对健康和环境有害。为了解决这些限制，SUNREY将通过一系列创新来解决这些限制因素的根本原因，这些创新涵盖了器件设计和制造的各个方面，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以配置为不同钙钛矿吸收剂的低成本沉积方法，开发稳定性更高的无铅材料，开发一系列从层到模块的阻隔和封装措施，以及工艺优化。这些技术的发展将得到新的方法来降解机制分析和建模的结合，以结合联合收割机的阻隔性能数据与设备性能模型和测试数据的基础。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真实实验室条件和户外条件下的测试来验证TRL 5。SUNREY的目标是实现高效率（25%含铅，15%无铅）与长寿命（25年）的突破性组合，与Si相比，减少排放和制造成本。这将为联盟公司开辟广泛的新机会，包括公用事业规模的面板，物联网和MicroPower，独立电源，建筑应用公用事业电力（BAPV）建筑集成光电技术。

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.
