Product Briefing Outline: mbj-Solutions is focusing on the development of electroluminescence inspection systems for inline and offline use along the photovoltaic production process. The latest product of mbj-Solutions is an offline solar cell inspection system. The operator can place a solar cell inside a drawer. By closing the drawer the system applies automatically current and voltage to the solar cell and captures an EL image. The image is displayed on the windows user interface. The system allows the user to investigate the solar cell and to discover problems in the production process.

Problem: Crystalline solar cells are sorted and the end of the solar cell production process by using camera systems to inspect the visual appearance and a light flasher to measure the electrical performance of the solar cell. The efficiency of the solar cells varies due to many reasons but the there is still a lack of opportunities to evaluate the reasons for varying efficiencies.

Solution: EL imaging is the technology to visualize any invisible defects such as shunts, micro cracks, finger defects and many other production process related phenomena’s. The mbj-Solutions SolarCell EL-basic is an offline tool to evaluate the quality of the production process for crystalline silicon solar cells. The easy and safe operation of the system allows the use at the production line for the first time.

Applications: The SolarCell EL-basic is designed for the use at the end of the solar cell production line and as well in the laboratory and can be used for: Mono- and multi crystalline silicon solar cells with 2 and 3 busbars. Back contacted solar cells on request. String ribbon and EFG cells are also possible.

Platform: All mechanical and electrical components such as power supply unit, PC, cooled NIR camera, automatic electrical contact unit are integrated inside the housing of the SolarCell EL-basic. To run the system only a monitor (VGA) and keyboard mouse (USB) and line power supply need to be connected to the system. For network use an Ethernet connector is available on the connector board. The system comes with a compact design and a price tag of €18,900.

Availability: Currently available.
