Research in PSCs has shifted from a race for efficiency to a race for stability1. While many commercial products exist to measure JV performance of these devices, there is a clear lack of solutions for reliable stability measurements with most groups still retorting to home-built systems.

For PSCs, it is important to keep the devices at maximum power point (MPP), as they degrade differently than Voc or Jsc2. This requires a parallelized system with multiple channels. Additionally, a highly-controlled environment is desirable for reproducible stability studies: temperature and atmosphere control as well as light source with UV component, round off the list of requirements2.

At Fluxim we released 2 products to specifically address these needs: Litos and Litos Lite. While differing in capabilities, both systems offer unique advantages for highly-reproducible parallel stability measurements in controlled environment. Litos Lite can additionally be used for power conversion efficiency (PCE) measurements under AAA solar simulator, while Litos can also be used for (O/P)LED stability studies. Both instruments are now commercially available and both can be configured for specific needs of the user with several optional modules and synergies with our other products possible.
