Chemists develop dye stack that mimics plant energy conversion

As a non-chemist, my memory is that every time this comes up (and it has done for decades) the problem is the stability of the dyes. It's like Peskovites in PV: lots of noise about significant energy improvement, not much noise about lifetime stability improving.

It's my non-scientific theory (and it is mine) that energy centric physical chemistry like this converting solar and other light sources into something tractable in another form of energy, which depends on quantum states coming in and out inevitably also depends on somewhat unstable compounds and atomic states. It's hardly surprising the "efficient" ones also tend to break down the reactants, and I would imagine even in a plant there is a process behind making Chlorophyll rich cells stable, and renew.
