As efficient measurement of terahertz (THz) radiation has become possible recently, this key technology is now to be developed for the photovoltaic industry. It would enable detailed analysis of photovoltaic cells, modules and materials and can also detect concealed surface structures, layer structures and materials that are not homogeneous.
The terahertz probing of photovoltaic substrates (TIPS) project uses THz radiation as a new tool in photovoltaics, for greater precision in quality control and as a non-destructive test method. The advantages of terahertz radiation and its successful use in photovoltaics will enable more accurate results and non-destructive test methods. New directions for the future and a strategic benefit for the photovoltaic industry will therefore be possible.
