Sunlight is the total spectrum of electromagnetic radiation emitted by the sun. On Earth, the atmosphere filters sunlight, and radiation is visible as daylight when the sun is above the horizon. When clouds do not block direct radiation, it is perceived as a combination of bright light and heat. 

The Sun: Our Primary Energy Source

The sun is the primary source of energy on Earth. Radiation from the sun strikes the Earth’s atmosphere and begins to be absorbed by air particles and gases, while the remaining power reaches the Earth’s surface. The Earth absorbs much of this radiation and also reflects and emits radiation. Even small changes to the balance of this energy system can cause intense shifts in the Earth’s climate.

Spectroscopy in the Solar Industry

As the world increasingly turns to renewable energy sources, the solar industry stands at the forefront of this transition, offering a sustainable solution to our growing energy needs. Within this dynamic sector, the role of spectroscopy has become vital in driving innovation forward.

Why Spectroscopy Matters

The measurement needs of the industry are pretty diverse, ranging from process control applications in the manufacturing of thin-film photo-voltaic panels to direct solar measurements and solar simulator characterization.
