The Photovoltaics Science, Applications and Technology Conference (PVSAT-2027) is a 2.5-day event, each year taking place at a different location in the UK. Running since 2003, it is the UK’s largest scientific event for the broad field of photovoltaics (PV), from materials to PV systems, where the latest advances in research and development are presented and discussed. PVSAT conferences address all PV technologies and applications, from crystalline silicon to perovskites, from microscopy to PV systems modelling, and from PV sustainability to space PV.
