Topic: 3. 1 Perovskites
Summary / Abstract: Perovskite-based semiconductorshaveconsiderable potential to becomean important technologyfor the fabrication of efficient thin-film photovoltaics (PV). Owing to the ease of fabrication byvarious wet-chemical deposition techniques,outstanding optoelectronic properties as well as simple bandgap tuna-bility, the international research community putsgreat effort into the technology’s development, result-ing insmall-areaperovskite solar cells exceeding25% power conversion efficiency(PCE) within only a decade of research. However, perovskite-based PVstill facesseveral challenges, such as low opera-tionalstability andthe need for upscaling of the fabrication processes to application relevant device areas. In this context, literature reports a clear trend of significant PCE losses duringupscaling of device area,as many established deposition processes become increasingly complex to control over larger ar-eas.
