Solar panels are designed to absorb light in the visible spectrum, but they can also absorb light in the infrared and ultraviolet ranges. The band-gap of a solar panel is usually between 400 nm and 1100 nm. Wavelength and frequency share an inverse relationship—higher frequency waves have shorter wavelengths, while lower frequency waves have longer wavelengths. Ultraviolet (UV) radiation has shorter. . The solar electromagnetic spectrum is primarily divided into three main regions: ultraviolet, visible light, and infrared radiation, which collectively span from roughly 100 nanometers (nm) up to 1 millimeter (mm).
