Technical Workshop on Space Solar Cells


The purpose of the workshop, organized by the TFQD consortium with the support of REA, is to present the results of recently completed and on-going projects funded under the H2020 COMPET and TEC calls from 2015, 2017 and 2018. It will bring together European experts, researchers, and policy makers to share emerging trends in space photovoltaics from a system-level  down to a device-level perspective.
