A solar cell is a device that directly converts the energy of light into electrical energy through the photovoltaic effect. Solar cells or photovoltaic cells are made based on the principle of the photovoltaic effect. They convert sunlight into direct current (DC) electricity. But, a single photovoltaic cell does not produce enough amount of electricity.
Silicon crystals are laminated into p-type and n-type layers, stacked on top of each other. Light striking the crystals induces the “photovoltaic effect,” which generates electricity.
