This talk will provide a comprehensive overview of the state of the art in development of emerging thin film PV technologies, possessing the highest potential for rapid scale-up uptake and mass deployment implemetation in building integrated PV (BIPV) and Internet of Things. . The research group, established a decade earlier, has extensive expertise in developing metal oxide, binary, and ternary metal chalcogenide thin films and nanostructured materials for solar cells and electronic and environmental applications. The 5GSOLAR project, which has received funding from the. . Starting from 1st of March, 2023, the group has a new name: Laboratory for Thin Film Energy Materials. The main research topic of the Laboratory for Thin Film Energy Materials is the development of metal oxide and sulphide thin films and nanostructured materials for solar cells, electronics and. . However, apart from the economic and ecological convenience, the development of BIPV brought about several possible applications for various building types. Evolving from the traditional add-on setup placed on the roof cover, modern PV modules can fulfil the roles of windows, terrace berries. . Unlike traditional silicon-based photovoltaics, thin-film technology enables solar energy harvesting on unconventional surfaces, from building facades to wearable electronics. This article explores the strengths of Estonian solar technology, market trends, and actionable insights for businesses seeking relia. .
