Solar panel performance is not the limiting factor in space. Thermal management is. Better solar panels don't help you here. Neither does permanent sunshine -- without the capability to radiate more heat at night, you've made the thermal management problem immensely worse.
Rockets: Launching no mass to orbit is even cheaper still.
Bandwidth: You do realize that even starlink speeds are crazy slow and high latency compared to data center optical connections? Fiber and copper always win out over wifi. With space, you are stuck with wifi. (Oversimplified, but accurate.)
Space solar power: there has been talk of this for half a century, yes. It never materialized because, like space data centers, it doesn't make economic sense.
