ISOS testing laboratory
infinityPV offers a complete testing laboratory for characterization of the solar cell lifetime behavior according to the ISOS protocol
Intrinsic and operational stability for solar cell devices are described through reporting the performance of a series of devices subjected to a number of different test conditions. Until now this has been achieved through use of a number of laboratory equipment. With the ISOS test laboratory you get it all in one “turn-key” package comprising: ISOSun solar simulator, test chamber, test equipment, a powerful software package and the accessories needed. With the ISOS test laboratory we prove that it is not necessary to spend a fortune to fully characterize novel PV technology such as organic, kesterite, perovskite, dye-sensitized and quantum dot solar cell technologies. With the ISOS testing laboratory you will have everything you need to record and report data from your experiments. It can easily be complemented with our LBIC systems that powerfully highlight failure modes from ingress, delamination, bubble formation once failure is established with the ISOS testing laboratory. Our LBIC systems are both a good companion and powerful “eyes” on the device where it functions and where it does not.
Key highlights
infinityPV ISOS test laboratory is unique on several fronts:
Full testing possibilities for ISOS-D-1/2/3, ISOS-L-1/2/3, ISOS-O-1/2/3
Full ISOS testing of up to 40 solar cells simultaneously
Data analysis and reporting
Large illuminated areas
Turn-key package comprising ISOSun, ISOS-L-3 chamber, ISOS-D-2, ISOS testing laboratory hardware, SMU, DAQ and MUX, cables & connectors, and software
Optionally we can include weather station and thermal cycling hardware
At the heart of the ISOS test laboratory is the ISOSun that presents a very high degree of homogeneity over the large area compared to size class A/B for all products (Class A over 10 cm x 10 cm, Class B over 32 x 32 cm). The ISOSun also has a very high degree of temporal stability (Class A) employing a stable metal halide light source with good spectral match qualified for ISOS testing. It is designed for continuous operation for many years and is very safe in use with little emission of light to the surroundings during testing. It does not interfere with adjacent equipment or experiments and has a flexible test compartment allowing easy access of any testing probe (wires, hoses, gas etc.) and of course the ISOS-L-3 humidity chamber. The outdoor platform is interfaced with the system allowing for simultaneous recording of data outdoor and indoor. Weather data (if available) and test conditions are stamped into the IV-data. It is a completely integrated system with no extra parts needed and has multiple integrated light and temperature monitoring sensors with easy control over light intensity and chamber temperature. Finally, it has an industry 4.0 ready test software package and present simple interfacing to robotics. We are proud to state that no competitors can match our current quality, adaptability, price, and flexibility in our range of solar simulators.
ISOS tests
There are nine ISOS tests that the ISOS test laboratory grants access to fully in compliance with the ISOS consensus [1]. As supplied the 40-channel system has dedicated channels to certain functions while you can of course configure this as required. In the standard configuration there are channels used for recording conditions (temperature, light intensity and humidity) and weather data. This data is always available as the system is running.
