Multilayered solar cells from Silicon Junction

In the race for ever increasing efficiency improvements in solar PV, Solar Junction have developed a new system which aims to harvest light from the sun more effectively by using a multiple layers. The solar junction devices which are designed for the CPV or concentrated applications are a leap forward in efficiency. Solar Junction was spun out of Stanford University and can generate up to 41.4% efficiency and this can be around x2 as much as convential solar cells.
