Calculator Solar Cell

Ramona Said:

In my calculator there is a solar cell what does it do and where is it connected you think?

We Answered:

Solar cells use solar energy or generally the energy of the light and transform it to electricity. The solar cell is some sort of semi conductor, that under the influence of light it forces the electrons to move in a certain way causing voltage differential and eventually current. Also it is connected to the battery in a parallel way, so that each battery pole is connected to each cell pole and altogether they're connected to the device's poles. This enables the solar cell to charge the battery and to provide electricity for the calculator, whereas if there's not enough light the battery provides the device with the essential power.
