ABOUT PULSED SOLAR SIMULATION

› Why Pulsed Solar Simulation?
Pulsed Solar Simulation has multiple advantages over constant light simulation:

- High maximum light intensity only during measurement
- No heating up of module or cell
- No cooling of light source or environment necessary
- Less power needed than constant light
- Flasher runs with standard power supply



› How long is the measuring time?
How long is the measuring time?
BERGER Pulsed Solar Simulators meet all requirements of IEC 904-9 Simulator Class A. The construction of the lamella light source and the patented flash tube ensure conformity with this standard over entire lifetime.
The electronically controlled discharge will hold the illumination level for up to 10 msecs. This allows the measurement of slow reacting solar cells or thinfilm products as well. The temporal instability is < ± 2%.



› How about homogeneity?
How about homogeneity?
The homogeneity is reproducible because of the defined light propagation without any optical elements like reflectors, mirrors or lenses. The non-uniformity of irradiance is <± 2%.



› How about spectral match?
How about spectral match?
The spectrum of a Xenon flash tube can be controlled better than that of an Xenon short-arc or other continuous light sources. BERGER patented flash tubes don't have to be filtered to reach Class A simulator requirements. The spectral match is 0.75 — 1.25.
