Yeah, but that was always a dumb idea, and it was always a minority position. Also we've know exactly why we can't have solar panels like that since [before] former thin film printed panel darling Nanosolar closed their doors in 2013: Microcracks develop in the protective plastic layers on thin film flexible solar panels and let in moisture which spoils the panel. You can make a relatively long-lived plastic solar panel if you don't want it to flex much, but it doesn't save much money in the end so that's done only for portable uses where glass is simply unsuitable.
You can make very cheap thin film solar panels. They just don't last long enough to be useful.
