The sun emits a complex and extensive spectrum of radiation known as its total broadband radiation, which encompasses many wavelengths from ultraviolet to infrared. This broad spectrum is vital for numerous industrial and scientific purposes. Solar detectors, particularly those sensitive across this wide range, are crucial for capturing and quantifying this celestial energy.
In the field of photonics, accurately measuring the sun’s total broadband radiation is of utmost importance. Solar detectors, through their capability to measure and characterise solar radiation, enable the development and optimisation of photovoltaic cells, solar thermal systems, and other technologies that harness solar energy. Additionally, precise measurement of solar radiation in scientific research aids in studies of solar phenomena, climate modelling, and the development of technologies designed to utilise solar energy more efficiently.
LASER COMPONENTS proudly offers thermopile detectors, which are integral to these applications. These detectors operate based on the Seebeck effect, where a temperature difference between two dissimilar conductors or semiconductors generates a voltage difference. In measuring solar radiation, thermopile detectors excel at converting thermal radiation into an electrical signal, providing a measurable metric for analysis. The spectral response of these devices is nearly linear from UV to NIR.
