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. |
Some 90 percent of solar cells are based on crystalline bulk silicon and there has been no sign of a breakthrough leading to a next-generation technology. We think we have come up with unique ways to do that. |
That is the long-term promise. |
Today there is a huge dependence on fossil fuel-based solutions. The sooner other solutions become cheap enough and… lead to massive widespread adoption, the better it will be for the environment. |
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. |
