Why is it that those are reserved for ultra-big utility companies and I cannot buy those for my home or even my balcony?

They're much more expensive than traditional silicon cells, they often use toxic materials (lead, cadmium, etc), and IIRC their lifespans aren't as long. Unless you have significant space constraints it's usually better just to get twice as many traditional panels.
At present, those tandem cells are still experimental. Nobody is manufacturing them on gigawatt scale like for other solar cell technologies.
