MPP Neo
IV, TPV, TPC, CE, (Photo-)CELIV - Semiconductor characterization for thin film solar cells
Applications
- Full compatibility to ISOS test protocols for perovskite and organic solar cells
- Aging in selectable electrical conditions: MPP, jSC and VOC
- Accurate control of illumination, atmosphere and temperature
- Degradation studies need statistics – degrade many devices at once
Functions
- Fully automated stability tests
- Up to 96 measurement channels per base unit, many base units can be combined
- Every channel can be configured individually
- 1 sun LED or metal halide lamp illumination
- Temperature controlled with electrical heaters or water cooling
Key features
- Every channel between +/- 3.5 V / 100 mA with a resolution of < 10 µV / 100 nA, MPP mode with selectable tracking algorithm or fixed parameter: jsc, Voc, defined voltage
- Selectable MPP tracking algorithm
- Base system configured with a web based graphical user interface
- Storing data to a network location or preconfigured NAS
- Illumination with white LEDs, metal halide lamps, LEDs with selectable wavelengths
- Environmental chambers for aging in controlled atmosphere e. g. nitrogen or dry air
- Temperature control unit for each environmental chambers to degrade at elevated temperatures or with constant water cooling
