Characterization of thin film solar cells
The Characterization of thin film solar cells is an important step in quality assurance. Together with the IRDEP (Institute of Research and Development on Photovoltaic Energy), Photon etc. has developed a PL mapper. This device supports the precise analysis of thin-film solar cells.
But why is this important? Thin-film solar cells can have structural defects that affect their performance. To detect such defects at an early stage, the photoluminescence method is used. The photoluminescence method is a key technique for Characterization of thin film solar cellsThe PL mapper improves efficiency in this low-light process. It achieves a transmission of up to 80 % and a spectral resolution of 0.3 nm. This allows even the smallest defects to be detected.
The design of the PL mapper has another advantage: It does not require an xy scanning device. This saves time and allows the results to be displayed directly on the array camera. For comprehensive Characterization of thin film solar cells In addition to photoluminescence, the device can also measure electroluminescence and diffuse reflection.
The PL-Mapper is versatile. It is suitable for both macroscopic and microscopic analysis. This means that users can examine either entire cells or just tiny areas. Characterization of thin film solar cells The PL-Mapper provides optimal support for quality assurance.
An additional advantage of the PL-Mapper is its high adaptability to different applications and materials. Thanks to the flexible configuration, the device can be used not only for thin-film solar cells, but also for other semiconductor components and optoelectronic systems. This versatility allows manufacturers to use the same system for different analysis techniques, thereby reducing capital costs and increasing efficiency. In addition, the PL-Mapper can be seamlessly integrated into existing production lines, enabling continuous monitoring and control of product quality. This ultimately leads to a higher yield and a significant reduction in scrap, which is economically beneficial for the solar cell industry.
