A realistic approach to increase the efficiency of photovoltaic (PV) devices above the Shockley-Queisser single-junction limit is the construction of tandem devices. PERCISTAND focuses on the development of advanced materials and processes for all thin film perovskite on chalcogenide tandem devices. This tandem configuration is at an early stage of development today. The PERCISTAND emphasis is on 4-terminal tandem solar cell and module prototype demonstration on glass substrates, but also current- and voltage-matched 2-terminal proof-of-concept device structures are envisaged. Key research activities are the development and optimization of top wide band gap perovskite and bottom low band gap CuInSe2 devices, suitable transparent conductive oxides, and integration into tandem configurations. The focus is on obtaining high efficiency, stability and large-area manufacturability, at low production cost and environmental footprint. Efficiency target is 30 % at cell level, and 25 % at module level. Reliability and stability, tested in line with International Electrotechnical Commission (IEC) standards, must be similar as commercially available PV technologies. High manufacturability means that all technologies applied are scalable to 20×20 cm2, using sustainable and low-cost materials and processes. The cost and environmental impact will be assessed in line with International Organization for Standardization (ISO), and must be competitive with existing commercial PV technologies. Such a tandem device significantly outperforms not only the stand-alone perovskite and chalcogenide devices, but also best single-junction silicon devices. The development will be primarily on glass substrates, but also applicable to flexible substrates and thus interesting for building integrated photovoltaic (BIPV) solutions, an important market for thin film PV. Hence, the outcome has high potential to strengthen and regain the EU leadership in thin film PV research and manufacturing.

CODATA and RDA will work with a set of domain and cross-domain case studies to implement and test FAIR recommendations, including those for core interoperability, to develop a set of recommendations and a framework for FAIR assessment in each discipline or cross-disciplinary research areas involved. CODATA and RDA are uniquely positioned to lead and coordinate this activity, as the two preeminent international, interdisciplinary data organisations. The Case Studies have been carefully chosen to provide maximum impact. They are clustered in cognate groups in order to maximise scope while retaining a critical mass of activity and allowing learning and cross-fertilisation of ideas among them. Drawn from CODATA and RDA activities and partnerships, the Case Studies include leading organisations in a range of disciplines and cross-disciplinary research areas, such that the outputs will have global influence and impact. The methodology is designed to maximise coordination, while being sensitive to the status and requirements of each Case Studies discipline or cross-disciplinary research area. Each Case Study will perform a lightweight benchmarking and information gathering exercise through preparing a FAIR Implementation Profile, appropriately adapted to their discipline. This will lead into, and help inform, a fuller mapping of current best practices and emerging solutions and initiatives in their discipline. Taking into account good practices in their disciplines as well as the draft framework for core interoperability, and pertinent RDA recommendations, each case study will develop, pilot and possibly deploy interoperability standards and guidelines. Finally, the reports and recommendations from each Case Study will be synthesized and used to develop discipline specific frameworks for FAIR assessment and benchmarks.

Artificial cooling fundamentally shapes the world in which we live. Since the onset of the Cold War, cooling and freezing technologies have become increasingly vital for a wide array of everyday practices, from nutrition, health and reproduction to dwelling, telecommunication, scientific research and economic productivity. A global system of cold storages, cold chains and air-conditioned spaces has become an energy-intensive yet barely considered planetary infrastructure: an “artificial cryosphere”. Artificial cold has drastically restructured life both on a biological and social level, yet the far-reaching impact of this technology is still largely unexplored and unresearched. Recent studies estimate that global cooling demand will increase five-fold by 2050, dramatically exceeding our future energy budget and urgently calling for change. CultCryo argues that avoiding the impending global cooling crisis will be impossible if we do not understand how the planetary infrastructure of artificial cold is deeply interwoven in cultural practices. Thus, in order to analyze the constitution of “cryogenic cultures”, we will undertake four interdisciplinary multi-sited case studies in the domains of food supply, air conditioning, biomedicine and computing. We develop innovative approaches using mixed-methods rooted in the history of technology, geography, digital history of concepts, ethnography and the philosophy and ethics of technology. Breaking ground for an innovative interdisciplinary field of research, CultCryo will provide the first geographical mapping of the cryosphere, a historical reconstruction of its emergence, an ethnographic account on its cultural constitution, and a philosophical analysis and ethical assessment of its underlying norms and values. Thereby, we develop a corpus of urgently needed knowledge to critically analyze a pressing global phenomenon while also identifying alternatives towards a more sustainable future of artificial cold.
