You can tune the photovoltaic to capture parts of the spectrum that have not efficiently been captured before with traditional methods - the red and the infrared for example.

Silicon in its bulk format we all know is not an efficient emitter but when you get down to the quantum-confined sizes, you get very different effects. For the smaller sized particles you can get blue emission and for the larger particles you can get red emission. By having a film of these devices, you can electrically stimulate them.
