  By your logic all solar panels would run out of these holes after a certain period of use?

    They might be right for other reasons though. I once worked at a lab where they were doing r&d on this sort of thin solar cells, and their stability and longevity was the #1 biggest problem. They worked great inside those anaerobic box thingies in the lab, but they degraded to nothing very quickly upon first contact with real atmosphere.

      Yeah but that’s experimental tech. OP’s talking about limitations on normal solar panels

        Im talking about limitations of thin solar cells largely. I think there is usually enough doped material in regular cells that it usually isnt looked at.

    Yes, is that not the case?

      No, definitely not. There’s no such lifetime limit.

        Why not? I have not looked at this in forever so im probably wrong but I thought that these pn pairs end up creating some band gap. Over time that band gap widens until the energy from the sunlight just isnt strong enough to move through the system. In the end, it has a finite qty of holes so that limit depends on the qty of doped materials.

        Again i dont remember well so 🤷
