Solar cells and batteries are similar in that they both produce electricity.

Solar panels.
Photovoltaic arrays are used( in conjunction with accumulators - batteries - to store energy when the satellite's solar panels are in shadow).
By solar panels, these will charge batteries, so they can operate if the are in the shadow of the earth.
They aren't needed, most calculators use batteries not solar cells.
Solar Cells are used to power Solar Panels.
None of the Apollo spacecrafts has solar cells. All of them used fuel cells and chemical batteries to provide energy.
There is an abundance of solar power in space, and a shortage of any other power. Satellites need power, and it would be difficult to get power to them any other way. Batteries would eventually run out, so a way of producing power needs to be included with the satellite. Solar cells are used for electric for the space hubs and satellite to keep it working.
Regular batteries will power a solar light until they run out of power. But regular batteries can't be charged from the solar cells unless rechargeable batteries are used instead. There is also a bit of circuitry involved.
