This is good but the real problem with solar cells is manufacturing cost not light absorbtion efficiency !
They are allready expensive - and 3d cells will be far more costly.
Existing cells manage ~20% efficient so the very best you can get is only 5* this but the cost to make them even the flat variety is the real killer. Unless the 3D cells manage to get 40%+ energy conversion and don't double costs to do it then it's not a much help.
New solar farms now are very happy to sacrifice % efficiency for much cheaper cells.
The big saver will be making cells which cost far far less even if only 10% efficiency even if they only have 50% absorbtion.
