Could lasers power solar panels?

I could imagine designing a solar cell tuned to a certain wavelength that could operate very efficiently from a laser. But… how would you power the lasers?

The reason solar energy is so desirable is that the source of energy is the sun, which we don’t have to pay for. That’s why, even with 20% efficient solar cells, it is still an awesome technology. Your source of energy is free and is shining down on you, so you can afford to toss away a lot of it.
