as promising as on earth, but cooling is also required

Two years before Sharp, in 2011, the American company Solar Junction has already released similar batteries, but with an efficiency of 43.5%, the elements of which had a size of 5 by 5 mm, and focusing was also performed with lenses, concentrating the light of the sun 400 times. The photocells were germanium-based triple junction cells, and the group even planned to create five and six junction photocells to better capture the spectrum. Research is carried out by the company to this day.

What's the point? If we were talking about heating the coolant, with further cooling somewhere in a turbine, then, in principle, one could try, but this idea is initially crazy for space. And semiconductor solar cells do not require focusing, moreover, it will be harmful for them, due to the same heating.
