Yes @Marty, I think the now mostly obsolete thin-film modules performed quite well in low light conditions but since their overall efficiency was very low (approx 10 to 12%) then they still didn’t come close monocrystalline modules with efficiencies of 15 to 17% at the time.
From what I know the main reason they were popular back in 2010 and earlier was due to the low price compared to monocrystalline panels.
