Yes – but you have to have power to make the lightbulbs work, so you actually lose energy. If, however, you're perhaps hoping to use a solar-powered calculator for a final exam, take it into the room before hand to be sure that there's enough light to make it work.

Even if you could it would be pointless. Why would you use an electric light to create electric? Kinda defeats the object
