Double Light Source Solar Simulator
Multijunction and tandem types of photovoltaic
module measurements are possible using this
double light source solar simulator
The conventional method that uses a xenon lamp only results
in xenon's unique bright line spectrum.
Using two light sources, namely xenon and halogen lamps, as
featured in our double light source solar simulator, enables the
bright line spectrum unique to xenon to be reduced in favor of a
spectrum which is closer to solar light. Various types of
photovoltaic modules including tandem types can be measured by
changing the intensity of the two light sources.
More accurate measurement of
tandem and triple types of photovoltaic modules
Tandem and triple types of photovoltaic modules with
layers of differing spectral sensitivity can accurately be
measured because two light sources, namely xenon and halogen
lamps, are used.
Measures the current-voltage (I-V)
characteristics of photovoltaic modules using pulsed
emissions from xenon lamps and constant emissions from
halogen lamps
Nisshinbo's original illumination control circuit is used
to achieve within ±0.2% of the temporal instability of
irradiance, which substantially exceeds even grade A.
Measurement of slow responding photovoltaic
modules is also possible
Photovoltaic modules with a slow response time can also
be measured, as the spectral balance can be adjusted by
changing the intensity of the two light sources.
No need to reverse modules.
Light is irradiated from below, enabling integration into
production line
Photovoltaic modules are manufactured with the receptor
surface facing down, and the modules are generally turned
over for measurement. We made improvements to our solar
simulator, and measurement is now possible with the receptor
surface of the photovoltaic cell remaining face down.
Eliminating the need to reverse the modules well facilitates
in-line operation, making it perfect for mass production.

- High-speed measurements in which measurement takes about
7 seconds with a general cycle time of 27 seconds per module
have been achieved.
- Supports expanded light pulse width and high-speed
measurement specifications (illumination control circuit
method). Measurement period is reduced by expanding the
light pulse width and measuring in one or two flashes (A
number of data points are collected per flash).
- Measurement results are immediately shown on the PC
screen, and can be printed from a printer at once.
- Optical filter is cooled using a filter-cooling unit
(circulation type).
- Capacitor recharging period is reduced by operating two
high voltage power sources in parallel per xenon lamp.
