On April 25, 2024, workshops were held in Prague, Czech Republic, as part of the COST RenewPV initiative. During these workshops, the latest achievements in the field of chalcogenide perovskites and Sb-based chalcogenides were presented and discussed. Presentations were given along with discussions on emerging chalcogenide technologies for PV applications, identifying challenges in material processing and device optimization, as well as their potential solutions. Additionally, attendees had the opportunity to establish new contacts. One of the participants in the workshops was Ph.D. candidate Przemysław Czarnecki, who presented the results of his ongoing doctoral work in a presentation titled "Textile substrates for inorganic flexible photovoltaic cells." The presentation showcased textile materials that can be utilized for photovoltaic cells integrated with textiles. The workshops were divided into four sessions, with two focusing on material synthesis and processing, and the other two on device development and the application of innovative solutions. In total, 17 presentations were delivered.
