Enhanced stability and efficiency in hole-transport-layer-free CsSnI3 perovskite...
Tin perovskite PV cells appear to be more stable than previously thought, making them a viable alternative to lead perovskite solar cells.

A Perovskite Oxide Optimized for Oxygen Evolution Catalysis from Molecular Orbital Principles
So getting oxygen out of water by electrolysis has traditionally been the limiting factor in performance. This new catalyst is apparently an order of magnitude better than the previous catalyst, but suffers from the same limitation, namely requiring an alkaline solution media to perform at its best. So perhaps not quite ready for primetime. However, apparently there are some integration possibilities with Dr. Nocera's artificial leaf project, which uses similar behavior catalysts.
