When you put a calculator into the sun, the sunlight will fall onto a special solar panel. There are photons in the sunlight that hit the material in the solar panel and knock electrons out. Those electrons are now free to move about and they form a current. So it's a way of getting sunlight and changing it into electricity to power the calculator.
