Seems durability is still an issue?  I've had Dye/GSL in the bottom draw for a while so haven't been following closly but I thought Dye/GSL had sorted, or were close to sorting, this issue some time ago?

"Whether perovskites can make that leap, though, depends on current research efforts to fix some drawbacks. Their tendency to degrade under heat and humidity, for example, is not a great characteristic for a product meant to spend hours in the sun. So scientists are trying to boost stability without killing efficiency."
