8th World Conference on Photovoltaic Energy Conversion; 1486-1489, The actual climate crisis generated by the global warming requires a strong civic participation to find a sustainable solution to overcome this critical time. The COP26, the UN climate conference, which took place last year in Glasgow, has the highest participation rate in COP´s history despite the global pandemic. The world was expecting more ambitious actions for a clean global energy transition to achieve the 1.5 degree-goal. It is now clear that this ambitious goal cannot be achieved only by political decisions. A strong civic participation is required to make sure that the global warming will not lead to an irreversible status of the climatic crisis characterized by climate events, which will make the life of human beings not more sustainable on this planet. Social innovations are the key to overcome this crisis and provide a sustainable solution to the mitigation of global warming towards the achievement of 1.5 degree-goal. Social innovations are defined as “New ideas (products, services and models) that simultaneously meet social needs (more effectively than alternatives) and create new social relationships or collaborations. In other words, they are innovations that are not only good for society but also enhance society’s capacity to act”. Source: Empowering people, driving change, Bureau of European Advisers (BEPA), Brussels (2011). In the renewable energy sector, social innovations are identified as the business models able to support the production of renewable energy and, at the same time, the cooperation among citizens. As common denominator they have the concept of “power of many” to highlight that, through the union of small contributions, it is possible to build projects having positive environmental, economic and social impacts. The business models implementing social innovation in the renewable energy sector are cooperatives, aggregators and crowdfunding platforms. The development of renewable energies and a greater civic participation will be the two pillars of the clean energy transition. Social innovations can combine these two fundamental aspects and lead to the energy democracy and, as consequence, to a mitigation of the global warming. This paper has been prepared in the framework of the European project SocialRES (Fig. 1), which has the aim to investigate the business models of social innovations in the renewable energy sector to provide the owners or managers of crowdfunding platforms and cooperatives and aggregators, named “the facilitators of energy democracy”, with new tools to further support the production of renewable energy and the participation of citizens.

38th European Photovoltaic Solar Energy Conference and Exhibition; 1494-1498, SERENDI-PV project is addressing some of the main concerns which would enable the increase in the penetration of PV generated power on to the European grids. On the one hand the project will address a reduction of the parameters which have the strongest influence on the risk perception for new investments in the sector in order to reduce the Levelized Cost of Energy, mainly associated with the new PV technologies such as bifacial, floating PV and building integrated PV: modelling (better energy yield assessments), faults diagnostics (increase the performance of PV systems), in-field quality control (better reliability), and forecasting. Special focus will be paid on issues that may occur to the PV plants, such as soiling (dust), snow and degradation over the years. On the other hand, the technical challenges and opportunities that will come with the increase of the penetration in the grids, such as the potential of PV to offer ancillary services, etc. will be assessed. Short-term forecasting and nowcasting fleets of distributed PV systems as a whole (aggregation) instead of PV systems alone will also play a key role in higher PV penetration and will be investigated in the project.

Essentials Platelet extracellular vesicles (EVs) concentrations measured by flow cytometers are incomparable. A model is applied to convert ambiguous scatter units to EV diameter in nanometer. Most included flow cytometers lack the sensitivity to detect EVs of 600 nm and smaller. The model outperforms polystyrene beads for comparability of platelet EV concentrations. Summary: Background Detection of extracellular vesicles (EVs) by flow cytometry has poor interlaboratory comparability, owing to differences in flow cytometer (FCM) sensitivity. Previous workshops distributed polystyrene beads to set a scatter-based diameter gate in order to improve the comparability of EV concentration measurements. However, polystyrene beads provide limited insights into the diameter of detected EVs. Objectives To evaluate gates based on the estimated diameter of EVs instead of beads. Methods A calibration bead mixture and platelet EV samples were distributed to 33 participants. Beads and a light scattering model were used to set EV diameter gates in order to measure the concentration of CD61–phycoerythrin-positive platelet EVs. Results Of the 46 evaluated FCMs, 21 FCMs detected the 600–1200-nm EV diameter gate. The 1200–3000-nm EV diameter gate was detected by 31 FCMs, with a measured EV concentration interlaboratory variability of 81% as compared with 139% with the bead diameter gate. Part of the variation in both approaches is caused by precipitation in some of the provided platelet EV samples. Flow rate calibration proved essential because systems configured to 60 μL min−1 differed six-fold in measured flow rates between instruments. Conclusions EV diameter gates improve the interlaboratory variability as compared with previous approaches. Of the evaluated FCMs, 24% could not detect 400-nm polystyrene beads, and such instruments have limited utility for EV research. Finally, considerable differences were observed in sensitivity between optically similar instruments, indicating that maintenance and training affect the sensitivity.

This paper reviews the present status and outlook of the building integrated photovoltaics (BIPV) market on a global and European scale. In particular, it provides a comprehensive review of the market situation and the future trends for Austria, Cyprus, France, Germany, Italy and the Netherlands until the year 2020. In addition, as education is seen as one of the barriers for BIPV deployment, results of a survey are presented that was conducted among BIPV stakeholders with the aim to identify major knowledge gaps in education and target audiences as well as teaching goals. From that potential courses dedicated to the needs of each target audience related to BIPV can be developed.
