Oh, I agree. I'm the commenter that pointed out the 150 days to 80% efficiency record. This is a total guess, but 150 days outdoors might translate to a few years of mostly-indoor use. But even then, there is probably need for more QC, etc. I'm just pointing out that there are other potential markets for PV tech that doesn't necessarily make sense for 30 years outdoors. TBD if that will work for perovskites (and honestly, TBD for dye-sensitized cells being a commercial success).
