The MBJ Mini Sunlike Lab is designed for the characterization of small modules in the development of new cell technologies such as perovskites in the laboratory.
The compact measuring system consists of a continuous light-capable sun simulator and an integrated electroluminescence camera. Modules up to a size of 450 x 450 mm can be tested.

Today, solar cells made of silicon are the standard. In the laboratory, silicon solar cells achieve efficiencies of almost 27 %, which is close to what is theoretically possible.
Higher efficiencies are only possible with new materials. A promising approach is the production of tandem solar cells made of perovskite and silicon. While silicon absorbs the red and infrared wavelengths of the solar spectrum particularly well, the perovskite crystal absorbs green and blue light particularly well. The combination of the two materials to form a tandem solar cell can then absorb more light and thus achieve higher efficiencies.
Tandem solar cells now achieve efficiencies of 33.9 % under laboratory conditions.
The LED units with 22 different LED types are ideal for laboratory measurements. The spectrum and intensity of the sun simulator can be easily adapted to your own test scenarios. Thanks to its continuous light capability, the sun simulator can also be used for preconditioning or aging tests. The flash time can be varied from 100 - 500 ms.
The LED unit can be scaled almost as desired, meaning that systems for single cells and even systems for modules can be built.
With the electroluminescence camera integrated in the MBJ Mini Sunlike Lab, a very compact test system can be set up that combines EL test and IV measurement in one system.
The intuitive software makes operating the system easier than ever.
Measurement sequences including heating, preconditioning, measuring and cooling can be easily configured with a mouse click using drag and drop.
