Selective emitter laser doping
WebLaser-assisted diffusion of boron has not been so extensively studied. However, controlled boron doping is a key procedure to produce selective emitter in n-type silicon and back … Proceedings of the 2nd International Conference on Sustainable Energy and … WebThe energy of the laser beam locally activates the P atoms to diffuse further down into the emitter and to locally enhance the doping level of the emitter, as illustrated in Figure 2. Figure 2: Schematic sketch of the LDSE process. The process flow of a conventional c-Si solar cell with and without LDSE is depicted in Figure 3.
