This approach might work in an industrial setting for photo-electrochemical applications but is highly unlikely for residential or commercial power generation.

This approach might work in an industrial setting for photo-electrochemical applications but is highly unlikely for residential or commercial power generation. mono-Si panels last for decades with no need for maintenance other than regular surface cleaning and no lead issues. However you could, in an industrial setting, do something like this: "Integration of a Hydrogenase in a Lead Halide Perovskite Photoelectrode for Tandem Solar Water Splitting 2020" https://pubmed.ncbi.nlm.nih.gov/32010793/ https://pubmed.ncbi.nlm.nih.gov/32010793/ Here you could use a catalyst regeneration strategy where you basically have a little production line onsite and as each unit wears out you just pop in a new one and send the old one to be regenerated, that's more plausible.
