Selective Emitters hold perhaps the greatest promise for efficiency enhancement within c-Si cell production. Laser-based tools have various roles within the different schemes already implemented or which form the basis of tomorrow’s high-volume production lines. Laser scribing (with short-wavelength nanosecond AVIA lasers) is performed at the front-end of Laser Grooved Buried Contact (LGBC) cells. Laser-assisted Dopant-Diffusion (either using the residual PSG layer or pre-deposited impurities) enables direct formation of strongly phosphorous doped regions. Here the short pulsewidths and fast (quasi-CW) pulsing from Paladin laser-based tools are ideal for production environments. Laser ‘doping’ can also be performed simultaneously with groove scribing or Dielectric Ablation.
