Halide perovskite solar cells have revolutionized the photovoltaic field in the last decade. Nevertheless, the two main drawbacks of this system, the use of hazardous Pb and the long term stability, still to be open questions that have not been fully addressed. Beyond perovskite solar cells halide perovskite are outstanding for the development of other optoelectronic device, causing that currently the research with these materials widespread to different optoelectronic fields and photocatalytic applications, where again stability and reduction Pb content still at the center of research effort. In the present talk, we will describe our efforts towards the application of these materials for solar-driven hydrogen production coupled to other processes like organic transformations and waste valorization. We will discuss on the rational design of halide perovskites containing non-critical raw materials towards photoelectrochemical processes, and the importance of extracting basic electronic and optical information to understand the carrier dynamics to maximize the performance and stability of these materials. Moreover, proper interrogation tools are needed to validate their photo(electro)catalytic activity and selectivity. The need for integration of the developed materials into tailored photoelectrochemical devices highlight the urgent need for stabilization strategies to move beyond the proof-of-concept stage to relevant technological developments.
