Jamis just to clarify the QTMM efficiency rate is what percentage. I see some posters toggling back and forth. Thanks for clarification and your opinion of course.

PSCs are improving fast. When they were first developed in 2009, they had an initial efficiency of 3.8%. Today, they can achieve efficiencies above 22%. In comparison, silicon solar cells have been around since 1880, only reaching efficiency levels of 26.1% in 2018.
