LED Solar Simulator provides illumination approximating natural sunlight (AM1.5G) in the wavelength range of 400 to 1100 nm. It assures controlled and repeatable laboratory conditions of spectral content, spatial uniformity and temporal stability for photo-electrochemical experiments meeting class AAA specification. Unlike traditional solar simulator based on Xenon short-arc lamp and metal halide discharge lamp, this concept is using high-power LED technology. The sun spectrum is matched using 6 LED wavelengths, sufficiently spaced apart to provide a uniform light. The main advantages of such a solution are: (i) low operating costs due to instant on/off; (ii) low maintenance costs because of the extended life of the LEDs; (iii) small size and low weight; (iv) low price.

Application note
Typical applications include visible-light photocatalysis, artificial photosynthesis and photo-electrochemical detection. The LED Solar Simulator has been designed to be used with redox.me photo-electrochemical cells. The cell position on the mounting rail is manually adjustable to provide optimum light focus on a sample. In order to supply the device, a power supply adapter should be plugged into a socket, and its output plug connected to the LED Sun Simulator’s socket. The LED Solar Simulator requires recalibration, every 6 months or every 1 000 work hours whichever comes first.
