Simulation of laser ablation of crystalline silicon solar cells by ANSYS

摘要

By the finite element analysis software ANSYS, we simulate a nonlinear model of laser ablation of crystalline silicon solar cells. Using thermodynamic method, the finite element model of pulsed laser heating crystalline silicon solar cells has been established. Adopting reasonable material thermal physical parameters description, meshing, thermal source model, initial conditions and boundary conditions, the ablation depth, ablation width and ablation morphology of laser ablating crystalline silicon solar cells have been simulated and compared with the experimental observations by scanning electron microscopy. The obtained simulation results are consistent with the experimental measurements.
