Photovoltaic panels are wavy
Solar panels are designed to absorb sunlight in a specific range of wavelengths. This range is known as the solar panel's "band-gap. The visible spectrum and some infrared and ultraviolet wavelengths are most effective for solar panels, while X-rays and gamma rays are too. . Solar cells depend on a phenomenon known as the photovoltaic effect, discovered by French physicist Alexandre Edmond Becquerel (1820-1891). It is related to the photoelectric effect, a phenomenon by which electrons are ejected from a conducting material when light shines on it.
