The NIPHO 26 conference  focused on recent advances in the field of hybrid perovskite based solar cells with a deeper look and particular emphasis into the current stability and upscaling issues, essential for the scaling up of this technology. Contributions delved into topics such as ways to improve stability and durability of devices from material design to more efficient and versatile configurations, interface engineering and physics therein, intelligent optimization approaches aiming at reaching the efficiency limits and the development of lead free solutions.

Emphasis was also be put on those advancements based on new ways to control stability through proper device interface engineering using organic and inorganic interlayer, perovskites with low dimensionality, as well as on the impact of those interface treatment on device stability and efficiency. Submissions encourageded on more fundamental aspects, such as the theoretical description of the electronic structure of perovskites, modelling of their optical and charge transport properties, or novel advanced characterization techniques.
