ISOSun Solar Simulator
A solar simulator made for controllable indoor test facility under laboratory conditions.
A Stable Solar Simulator
The ISOSun is a stable solar simulator that provides homogenous light simulation over large area with easy implementation of filters, neutral density filters, cooling and wiring. It is optimized for longterm lifetime and stability studies of photovoltaic devices and various materials.
The ISOSun solar simulator enables reproducable testing of large PV devices up to 30 x 30 cm2 according ISOS* protocols. Optional hardware provides simultaneous testing of up 40 devices. The large experimental compartment with ventilation fans enables good access with easy wire routing for external measurement devices.
An integrated temperature sensor and photo diode provide instant data acquisition and make adjustments possible.

How Does the ISOSun Work?
Operating the ISOSun
Operation
The ISOSun system is fully enclosed with little emission of light to the surroundings and has a facile system for introducing wires, gas lines and cooling lines to the test area. The system is fully CE approved and accepts line voltages in the range of 110-240 VAC (single phase). All maintenance is made very easy with the change of the light bulb being carried out from the top in a matter of minutes without the need to take the setup apart. Filters and dampening ND filters are easily inserted and removed through a tray system. The lamp intensity is easily monitored and controlled from the front panel and the system has an internal light monitoring unit.
Testing
Combined with our Source Measure Unit and IV and Lifetime software, the ISOSun enables IV-curve tracing and testing according to all the ISOS protocols. With the ISOSun and the infinityPV software ISOS-L-1 and ISOS-L-2 testing are readily carried out and it is easy to set up the system (without extra equipment) so that ISOS-D-1 and ISOS-O-1 are also accommodated.
With a multichannel system (optional) it is possible to test many samples (up to 40) simultaneously and here also ISOS-O-2 and ISOS-O-3 becomes accessible. For the high temperature ISOS-D-2 dark test an oven can be provided through an external supplier (optional).
Since most laboratories have an oven already available this test is easily accessed. The damp heat and temperature cycling tests require weathering chambers that we can supply through external suppliers such that ISOS-D-3 and ISOS-L-3 becomes accessible. Laboratories that already have such equipment available can carry out the tests using the ISOSun combined with the infinityPV software.
Optional Equipment
High Power 4 Channel Source Measure Unit
The High Power 4 Channel Source Measure Unit is versatile, catering to both small laboratory PV devices and larger PV modules with higher power levels, offering a maximum of 5000 mW per channel.
Low Power 8 Channel Source Measure Unit
The Low Power 8 Channel Source Measure Unit is specifically tailored for laboratory PV devices and compact modules, supporting voltages of up to 5 V and currents of up to 40 mA, with a maximum of 200 mW per channel.
CalCell Reference Device
A calibrated photodiode and filter to calibrate light intensity precisely at your sample’s position. Unlike internal reference diodes, the CalCell accounts for factors like sample geometry, fixture, and position, ensuring confidence in your experimental results.
