Photocells are devices that transfer light energy directly into electrical energy. They produce DC - direct current - electricity. This is electricity in which the current moves in the same direction all the time.
The output of photocells depends on the surface area that is exposed to light. For a given light intensity, the larger the area, the greater the power output.
Solar panels do not generate electricity - rather they heat…
