You missed the point.
We can make ten or hundred times the number of solar cells we make right now, we just don't have a reason to. The technology is fairly ancient unless you want to compete on efficiency, and the raw materials abundant.
you would need 200 times the number of solar cells. I don't think you appreciate the scale that 200x is, especially when China is already:
1. quite good at making solar cells
2. quite motivated to increase their energy production via solar
The limit isn't just about the current capacity or the maximum theoretical capacity, it's also about the maximum speed you can ramp.
