A schematic of a typical setup (taken from the ASTM E1021-15standard) is shown below. We start with a broadband light source, meaning one emitting a wide range of wavelengths. In order to not be as heavily influenced by dark current and give a more accurate snapshot of the device under its intended working conditions.

AI Customer ServiceYou can effortlessly test the efficiency of your solar cell device using the Ossila Solar Cell Testing Kit — which combines our solar simulator with our source measure unit and test board. There are several methods used to characterize solar cells. The most common and essential measurement you can take is the current-voltage (I-V) sweep.
Of coruse, you could use actual sunlight, but this would introduce an uncontrollable variable. To test solar cells reliably, you need to maintain controlled conditions within your lab — and this is impossible to do while allowing direct, unfiltered sunlight onto your testing equipment.

There are several methods used to characterize solar cells. The most common and essential measurement you can take is the current-voltage (I-V) sweep. From this, you can calculate all the necessary device metrics needed to work out the efficiency of your solar cell. The I-V sweep is a quick measurement.
Instead, during PID cell test single-cell encapsulated solar cells are tested and exposed to the exact same conditions which are known to cause PID: elevated temperatures and a high electrical potential between glass surface and solar cell. For this purpose, the layer stack structure of a solar module is simulated on the solar cell.
To test solar cells reliably, you need to maintain controlled conditions within your lab — and this is impossible to do while allowing direct, unfiltered sunlight onto your testing equipment. Additionally, many potential solar cell materials are unable to withstand weathering effects during the early stages of development.
