Figure 1 :  The mini solar module after scribing.

  The laser scribing, which means digging lines within the layers of the solar cells, is a significant process within the fabrication scheme for solar cells modules. Scribing is done in order to contact the cells within the module, upscale the area of ​​these manufactured modules for industrial applications and save the efficiency in the meantime.
My project is concerned with the scribing of the absorber material layer of CIGS thin film solar cells. This involves optimization of the parameters of the lasers beams, pico and nanosecond ones , and comparing, qualitatively and quantitatively, the mechanical and laser scribing approaches in order to determine the optimum approach for industrial scaling .

  1. Nice introduction and good explanation of the project. I would like to know more about it.

  2. How these small modules are scaled up to the industrial level? I would like to hear about the connection between lab scale and industrial scale in PVcomb.
