A little known fact about solar cells is that they become increasingly inefficient the hotter they get. So sticking them out in a desert doesn't get as much energy as you might expect.
Now though, scientists have worked out a way to use both the light and heat from the Sun at the same time, more than doubling the efficiency of solar energy production. This, and the fact that the new technology uses cheap materials, means it could compete on even terms with oil based energy. More here.
