Application of laser texturing method for mc-Si solar cells fabrication
The results of the experiments on the “black” mc-Si surface fabrication by the nanosecond pulses of the YAG laser second harmonic and on application of the introduced laser texturing method for the mc-Si solar cells efficiency improvement are represented. The developed version of laser texturing permits producing a low-reflection mc-Si surface with the reflectance of ~3% in the spectral range of 0.3-1.1 μm. The application of the introduced laser texturing method in mc-Si solar cells fabrication makes it possible to increase the short circuit current density and quantum efficiency.
