Solar cell efficiency goal

The efficiency of solar cells with multijunction concentrators is increasing since 1988. In the image we can see a great development of the Three-junction solar cell.
Now, scientist has designed a new multijunction solar cell, with am efficiency of 51.8 %.

(—Scientists have designed a new multijunction solar cell that, in simulations, can achieve an efficiency of 51.8%. This high performance exceeds the current goal of 50% efficiency in multijunction solar cell research as well as the current world record of 43.5% for a 3-junction solar cell.
