LumiSolarCell PL
Innovative high-power LED-based PL inspection system
The characterisation methods of the LumiSolarCell PL using photoluminescence (PL) include several advanced techniques. PL imaging is utilised to visualise the luminescent properties of the solar cells, while biased PL provides additional insights under various electrical conditions.
Additionally, the mapping of minority carrier lifetime is performed to assess the efficiency and quality of the solar cells by measuring how long charge carriers can exist before recombining. These methods collectively offer a thorough evaluation of the solar cells performance and material properties.
Successfully tested on various Solar Cell types:
- Monocrystalline Silicon (mono-Si)
- Amorphous Silicon (a-Si)
- Copper Indium Gallium Selenide (CIGS)
