You're right, but I was thinking about electicity generating solar panels. Si has an extra electron that it can pass to a complimenting metalic oxide thus creating DC current. A big problem with them is their cost. There is a slight chance that this might work, but it would have to crystalize as I dried. If it does then the price should plummet. ('Should' being the operative word:)
