Where is My Solar Cell?

David Biello tweets:
"once again the Nobel goes to chemists for finding a way to do in lab... what plants, animals, our bodies do every day
I was thinking about something similar the other day: why has no animal ever evolved to have a self-contained solar cell that would directly convert sunlight into the energy they need to survive?

Instead we all  have to go through this stupid cycle of eating the plants that can covert sunlight into energy (or, worse, of eating the animals that eat the plants that convert sunlight).

Why haven't I simply evolved with a bio-solar panel on top of my skull and back?
