Performance Improvements of Selective Emitters by Laser Openings on Large-Area Multicrystalline Si Solar Cells
Table 1
The variation of the average lifetimes (τ, in μs) of mc-Si wafer corresponds to different processes for laser fluences (J/cm2) of 5, 3.5, 2, and 0 (as a Ref. cell) after steps of acid etching, laser ablation, ARC, and passivation. The average lifetimes for the acid etching step of all samples are 7.36 μs.
