How does the solar energy work?

Solar energy technology work by converting sunlight into electricity. Sunlight is needed to excite electrons in a photovoltaic(PV) material, also called a solar cell. Solar cells or photovoltaic (PV) cells work using the photoelectric effect principle where electrons in a semiconductor material are excited giving rise to free electrons that move in one direction through a PN junction. Semiconductor materials are used in solar cells because they exhibit the characteristics…
