Solar Cell Sets Record at 40.8 Percent Efficiency
This is a really big deal. I remember talking to Collins about this a while back and the big problem with large scale solar power has been the low efficiency vs. the cost. These kind of breakthroughs change the playing field and make it more and more practical.

This cell is not for home solar. The is for a solar concentrators, arrays, or possible space based solar farms. It needs concentrated light to acheive this effiency.
Sadly, home/roof based solar cells lag way behind this.
