The 3D allows for more surface area, meaning more surfaces are available to receive light. The cells are also able to receive multiple "colors" (light frequencies). |
Check out the following article on spectrum efficiency:

It seems to me like the best solar cells (Indium gallium nitride apparently) are already using most of the spectrum. But hey, I'm not an expert.
