28/30% cells are common in spacecraft and have been for more than five years, but they are expensive. A little less than 10k for something like 1 square meter only for the cells wouldn't be crazy.

That's pretty great! https://www.spectrolab.com/photovoltaics.html#cells_cics https://www.spectrolab.com/photovoltaics.html#cells_cics (That last link was supposed to be for the concentrator section at the bottom of that page, but I don't think it's a normal # bookmark)
