Recently, the area of photovoltaics has been overwhelmed by the introduction of hybrid halide perovskites with efficiencies skyrocketing to levels of > 25%. At the same time, perovskites afford low-temperature solution processing, which opens prospects for large-area solar cells produces at low cost. The outstanding progress of perovskite solar cells (PSCs) triggers the question about commercialization of the technology. However, the steadily increasing efficiency of PSCs is still accompanied by concerns of long-term stability and open questions about upscaled manufacturing. Further progress of this technology requires an in-depth understanding of material specific properties and limitations along with insights that allow to identify solid links between processing technology and resulting material properties. Novel device architectures are needed to afford further improvements in efficiency and stability. A further big challenge is the sustainability of perovskite solar technology, which requires the development of green production technologies (choice of precursors, chemicals, minimizing waste and developing concepts to recycle) as well as minimizing the use of scarce raw elements (such as Indium etc.) and identification environmentally benign constituents (replacement of lead, etc.)
That said, the proposed Summer School will be a forum to discuss in particular recent
advances, problems and prospects for engineering commercially effective and sustainable perovskite
solar technology. Therefore, aside from fundamental scientific issues, the practical implementation
of PSCs in the renewable energy sector will also be addressed in the lectures and short talks to be
presented to the auditorium of the School
