Sprayon solar cells would be a major breakthrough all by themselves.

From what I have read the trend is to use more sophisticated semiconducter devices that can capture more energy per unit area than the typical amorphous silicon cells.

This sprayon technology is most likely just a cheaper way to create amorphous silicon, so it will be as inefficient (if not moreso) than current technology.

Since semiconductor manufacture has become so cheap, it may be best to continue down the route of ever more complex and efficient solar collecting devices which can be packed every more tightly rather than just making the amorphous silicon technology a bit more cheaper to produce.
