PSCO17 will be held in Oxford, United Kingdom from 18th – 20th September 2017. The programme will include a combination of invited talks, contributing talks and poster presentations in a meeting which will bring a broad spectrum of the community together to discuss and share knowledge on the latest advances in perovskite materials, devices and photophysical and optoelectronic properties and phenomena. Educating young researchers is at the core of our mission, which will be enabled by the opening tutorial lectures, in addition to a whole series of invited talks by world leading scientists in their respective specialities.
