Energy conversion is a tough game.

The upper limit for a single junction silicon cell is around 30% (can't remember the exact number and it depends on your assumptions), so we are already approaching the point of diminishing returns for this specific configuration.

Multijunction cells or TPV cells can go higher though, we just can't do them as cost efficiently yet.

Cool!
