[Abstract]:In view of the difficulty that the diffusion zone of solar cells can not be measured accurately, the application of simulation software can better study the diffusion zone of solar cells. The two-step diffusion process of solar cells was simulated by using SILVACO software. The effects of different secondary diffusion processes on the performance and diffusion zone structure of solar cells were explored. The wet oxidation diffusion process, silica protective diffusion process and non-oxygen diffusion process were simulated and designed respectively. The simulation results show that the secondary diffusion process of wet oxidation can increase the concentration of impurity on the surface of the battery and form a shallow PN junction. Through the simulation of the spectral response of three different processes, it is found that the optimum spectral response can be obtained by using the wet oxidation secondary diffusion process. Through the study of the diffusion temperature and the pre-deposition concentration of the wet oxidation secondary diffusion process, it is found that with the increase of the secondary diffusion temperature, the short-circuit current of the battery increases first and then decreases, and with the increase of the pre-deposition concentration, The short circuit current of the battery first increases and then decreases.
