All-Inorganic Halide Perovskite Nanocrystals (NCs) have emerged as a new class of fascinating nanomaterials with outstanding optoelectronic properties, with promise to revolutionize different disciplines like photovoltaics, lasing and emission. In the present talk, we will describe our efforts towards the application of these materials for solar-driven processes spanning from photocatalysis, environmental remediation,[1] H2 production and waste valorization.[2], We will discuss on the rational design of these fascinating materials towards photoelectrochemical processes, and the importance of extracting basic electronic and optical information to understand the carrier dynamics,[3] the influence of trap states and to define adequate defect passivation strategies to maximize the performance and stability of these materials. Moreover, proper interrogation tools are needed to validate their photoelectrocatalytic activity and selectivity. The development of autonomous photoelectrochemical devices based on these materials will be discussed on the basis of recent results from the European Innovation Coucil Project OHPERA. 

This work was supported by the European Innovation Council (EIC) via OHPERA (grant agreement 101071010) project.
