The SUNREY consortium consists of 13 European partners including research organizations, universities and companies: Fraunhofer-Gesellschaft (Fraunhofer IAP), Universita Degli Studi di Roma Tor Vergata, CYCLECO SAS, AIT Austrian Institute of Technology, Dyenamo AB, Great Cell Solar Italia Societa ’A Responsabiliata’ Limitata, Materia Nova, Universidad de Córdoba, n-ink AB, and Technische Universität Graz. “We are thinking of new applications of such solar modules in microelectronics for the Internet of Things (IoT) or grid independent power supply of building integrated photovoltaics.” “Our developments will enable the companies of our consortium to improve their capabilities for the fabrication of solar cells, taking another step towards a CO2-neutral future,” explained Wedel. 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. Thirteen partners – research institutes, universities, and companies from all over Europe – combine their competencies to overcome the drawbacks of perovskite photovoltaics. Life cycle, circularity and stability analysis as well as lifetime analysis under realistic lab conditions in an accredited laboratory are accompanying this development. Simulation of device and degradation mechanisms are a central instrument for reaching these goals. SUNREY stands for “Boosting SUstaiNability, Reliability and EfficiencY of perovskite PV through novel materials and process engineering.”īesides the development of novel perovskite materials with reduced lead content, the objectives of the project are more stable and more efficient materials, novel charge transport and electrode mate-rials, cost efficient deposition techniques, barriers and device encapsulation as well as process optimization. Armin Wedel, who coordinates the EU project and is head of the Functional Polymer Department at Fraunhofer IAP in the Potsdam Science Park, Germany. In addition, we are pursuing further strategies to make perovskite solar cells more sustainable, efficient, inexpensive and durable,” said Dr. To this end, we are developing materials with low lead content. “Making perovskite solar cells more sustainable and efficient in order to have less impact on the environment is the central goal of the SUNREY project. Thus, further development in materials is needed in order to reduce or eliminate lead in perovskite solar cells while maintaining efficiency and stability. For lead, the maximum permitted concentration in homogeneous materials is 0.1 percent by weight. According to the RoHS directive of the European Union hazardous substances such as lead are to be avoided in electrical and electronic devices. In addition, the currently best performing perovskite materials contain lead, which is harmful to health and environment. The low stability of the perovskite materials and short life times of the modules still prevent a broader commercialization. In addition, the temperatures required during production of perovskite solar cells are lower, which saves costs and energy. Less CO2 equivalents are emitted during their production. Their efficiency is very close to that of silicon solar cells. An alternative are solar cells based on perov-skite technology. However, the technology has limitations, such as high-energy production. The three-year project started on November 1, 2022, and is coordinated by the Fraunhofer Institute for Applied Polymer Research IAP in Potsdam, Germany.Ĭurrently, silicon is the material of choice for the fabrication of solar cells. SUNREY is funded by the European Union’s research and innovation program Horizon Europe within the framework of the Green Deal Initiative with €4.25 million. The project aims to further push the development of highly efficient solar cells based on non-critical raw materials and to strengthen the innovation potential of the European industry. Making perovskite solar cells more sustainable, efficient and durable – these are the goals pursued by 13 European partners in the project SUNREY.
