Boosting SUstaiNability, Reliability and EfficiencY of perovskite PV through novel materials and process Engineering . (SUNREY)

13 partners - research institutes, universities, and companies from all over Europe combine their competencies to overcome the drawbacks of perovskite photovoltaics.
SUNREY will be carried out in close cooperation between science and industry, in order to strengthen the innovation of the European industry along the value chain. Our developments will enable the companies of our consortium to improve their capabilities for the fabrication of solar cells, taking another step towards a CO¬2-neutral future. We are thinking of new applications of such solar modules in micro-electronics for the Internet of Things (IoT) or grid independent power supply of building integrated photovoltaics.

Sunrey will develop enhanced characterisation and modelling methods including use of electrical impedance spectroscopy coupled with modelling and material characterisation including interaction between
environment, materials and structure to better understand degradation pathways and predict lifetime-limiting mechanisms. These models will be linked to accelerated testing regimes and test equipment design to provide the basis for material and device optimisation and for prediction of device and module lifetime. This activity will encompass the influences of module design, encapsulation and barrier properties as well as material design and cell architecture.
SUNREY will perform comprehensive testing and evaluation at laboratory scale including outdoor testing and compliance with the relevant protocols (ISOS), characterisation for reliability and energy yield assessment and generation of data to support performance and lifetime models. Testing will be conducted by an accredited solar PV test lab (AIT) as well as at partner facilities around Europe.
SUNREY will develop comparative, toxicological and environmental impact models, including life cycle assessment and life cycle cost analyses (including decommissioning and disposal) to bring evidence of the low environmental impact and demonstrate better resource efficiency and more efficient circularity than current commercial PV technologies. These will be applied to materials and processes developed in the project, feeding back to the design process to ensure safe and sustainable designs.
SUNREY will develop scaleable processes to implement the new materials, solar cell and module designs with a focus on low-temperature solution-based processes that can be applied to a range of substrates such as flexible. The development of tuneable charge transport layers meets an important requirement for fully exploiting bandgap tuneability of perovskites. This will open up new applications with targeted markets including utility-scale panels, IoT and MicroPower, Independent Power Sources, Building Applied Utility Power (BAPV) Building-Integrated Photovoltaics.

The role of University of Cordoba is to develop novel mixed 2D/3D halide perovskites with conjugated p-conjugated organic diammonium cations to enhance the stability of perovskite solar cells under operation from several hundreds to several thousands hours. Current lifetimes of Pb-based perovskites are too short for commercial applications.
