What is the difference between photovoltaic cells and solar cells?

photovoltaic effect & photoelectric effect – how solar panels work

Photoelectric effect comes in action once enough photons are absorbed by the negative layer of the photovoltaic cell, due to which electrons are freed from the negative semiconductor material. The structure of the PV cells allows the free electrons naturally migrate to the positive layer creating a voltage difference.

What Is the Photovoltaic Effect?

Solar cell

A solar cell or photovoltaic cell (PV cell) is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect.
