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

钙钛矿光伏在过去十年中取得了快速发展，具有更高的效率，减少嵌入式能源和二氧化碳排放，低温生产等多种应用，如柔性光伏，并且所有这些技术的成本都比目前的Si技术低得多。然而，稳定性差和使用寿命短阻碍了钙钛矿光伏的广泛应用。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，这些创新涵盖了设备设计和制造的各个方面，包括提高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为不同钙钛矿吸收剂的低成本沉积方法，开发提高稳定性的无铅材料。开发从层到模块和流程优化的一系列屏障和封装措施。这些技术的发展将得到退化机制分析的新方法的支持，并将建模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。开发将通过认可实验室在实际实验室条件和户外条件下的测试来验证TRL5。与硅相比，SUNREY的目标是实现高效率（25%含铅，15%无铅）、长寿命（25年）、低排放和低制造成本的突破性组合。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，物联网和微电源，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.
