Abstract :
OM&T | Moser Baer Technologies is investigating the approach of texturing glass up to Gen5 size (1.1 × 1.3 m2) by nano-imprinting techniques. For the application of thin film silicon solar cells nano-imprinted 2D periodic gratings were successfully developed and tested as light trapping textures that can realize an increased solar cell efficiency and/or allow to reduce the thickness of the absorber layers. Reliable materials were found and compatibility of the nano-imprinted light management layers with solar module manufacturing processes was demonstrated. Scaling-up towards Gen5 size was realized by first moving from laboratory to Gen2 scale and to incorporate the findings into a processing line that can be used for the production of Gen5 size textured glass.
