I'm not sure about cost,but a university in Toronto,Canada has come up with a durable, 4-junction,laminated,perovskite,low-temp,low-cost,PV,with an independently-certified 30% power conversion efficiency.This would exceed Gallium- arsenide,space-grade, silicon cells at a fraction of the cost.
Something like this might help.
