So, who's right? Is the article overstating the stability problem or are these companies over-promising?

However this is not good enough when 25+ Years lifetime is required (residential or utility scale).
Another niche use case is quantum glass by ML System. Generate energy from windows. Great for IoT, smart windows, new buildings, cars, but energy density is fraction of typical PV panels.
I think neither. "Several years" is still a huge problem. That's way too short.
Just thinking aloud, but think about a (very, very) large (traditional) camera, you have this roll of film that you advance one frame at the time, and then expose to sunlight.
Once every - say - two or three years, when it doesn't produce anymore enough electricity, you advance one frame and once every (say) ten or twenty years, you change the film roll.
The regular price for monocrystalline silicon solar panels is around $0.21/watt on Alibaba ([1]), not including shipping from China (which may vary, depends on the volume, destination and current rates).

there is a scheme of the government who give subsidized solar water pumps at a installed price of $0.12/watt" for the solar panels, water pump, fixtures, wiring, instalation, labour, spares. i plan to "request" farmer friends to buy me 10-15Kwh worth of panels which i plan to install at my home
That certainly is...a sentence.
That comment was made well over 40 years ago.
- stability when exposed to oxygen (as in they don't last in the real world)
- lead (disposal issues, which are important because they don't last)
Have things improved recently? I'm going to assume that the "Colorado Sun" won't represent state of the art.
