That’s the thing, since First Solar started in Tucson AZ back in 1999, they were making perhaps 12% to 13% panels in smaller footprints. They tried some early on small footprint installations of their series 4 panels on homes. The silicon cell solar PV panels were more output per square foot of roof space, so they won out. Then first Solar did two things, they found out by going to 24 square feet, these utility scale panels could be made up to 18.3% light capture efficiency, last as long as crystal silicon cell solar PV panels, work a little better in low sun or hot conditions and use much less energy to manufacture, the series 6 utility solar PV panel was born. Just last year First Solar announced they would power all of their solar PV manufacturing with solar PV generated electricity, by 2028. First Solar is also on the committee of the DOE’s solar PV R&D projects. Since First Solar has 20 years of experience with thin film solar PV, it would make sense to let them lose on trying to either use or incorporate the often touted perovskites into a solar PV panel with 30% or more energy harvest efficiency, with 25 plus years of generation life expectancy.
