Halide perovskites show good photovoltaic performance surpassing conventional solar cell technologies. A good photovoltaic material with good stability is expected to be implemented in solar fuel systems. However the poor stability of these materials hampers them from being employed as such in photo/Photoelectrocatalysis and surface protection deemed necessary to implement them in these systems. We have recently discovered that Cs2PtI6 that comes under a class of vacancy ordered perovskites to be stable even in strong acidic and basic environment. This material also shows panchromatic absorption upto ~950 nm. This talk will focus on the electrochemistry of Cs2PtI6 and their application in solar water oxidation.
