The visible region extends from 400 to 700 nm. UV photons have energies ranging from approximately 3 to 5 electron Volts (eV). The UV includes light with a wavelength shorter than 400 nanometers (nm).

The solar spectrum can be divided into three main regions: the ultraviolet (UV), visible, and infrared (IR). Solar radiation is the direct emission of energy from the sun while solar irradiance is the amount of energy that reaches the Earth’s surface. It can be defined in terms of solar radiation or solar irradiance. It is composed of photons with various wavelengths, which define the spectrum’s shape and intensity. The solar spectrum is the range of electromagnetic radiation emitted by the sun, extending from the ultraviolet to the infrared region. An overview of the most important factors affecting the light we receive are covered below. As a result, replicating it presents a challenge. Sunlight starts its journey through complex nuclear reactions in the sun’s core and is then modified through interactions with the Earth’s atmosphere. There are a number of factors that determine the shape and features of the solar spectrum. Classification of solar simulators is in part dependent on how accurately they can replicate this spectrum, so it is very important to consider when designing a solar simulator. The recognised reference spectra most often used as the standardised solar spectrum is the AM1.5 spectra. A spectrum shows the intensity of light as it varies with wavelength – so a solar spectrum tells us the measured intensity of light we receive from the sun at various wavelengths. To do this, we need to accurately replicate the solar spectrum.

The purpose of a solar simulator is to recreate the sunlight that we receive on Earth as closely as possible.
