Si thin film solar cell with asymmetric p-n junction
We propose an asymmetric structure using simulation to improve the electrical characteristics of the solar cell. This structure is designed by shrinking the bottom core diameter in radial structure. It causes the total reflection of the incident light in the outer wall and the light concentration in the bottom core. Consequently, an asymmetric solar cell (ASC) shows the increase in current density and cell efficiency (CE), which is 10 % higher than those of a symmetric solar cell (SSC). By increasing doping concentration of the shell and applying light trapping techniques i.e. anti-reflective coating and back-surface-field, the ASC showed high CE compared with the SSC. This novel structure offers an opportunity for effectively improving the CE.
