Effects of annealing on ion-implanted Si for interdigitated back contact solar cell
چکیده انگلیسی

Effects of annealing on the properties of P- and B-implanted Si for interdigitated back contact (IBC) solar cells were investigated with annealing temperature of from 950 to 1050 °C. P-implanted samples annealed at 950 °C were enough to activate dopants and recover the damage by implantation. As the annealing temperature was increased, the diode properties of P-implanted samples were degraded, while that of B-implanted samples were improved. However, in order to activate an implanted B ion, B-implanted samples needed an annealing of above 1000 °C. The implied Voc of lifetime samples by quasi-steady-state photoconductance decay followed the trend of diode properties on annealing temperature. Finally, IBC cell was fabricated with a two-step annealing at 1050 °C for B of the emitter and 950 °C for P of the front and back surface fields. The IBC cell had Voc of 618 mV, Jsc of 35.1 mA/cm2, FF of 78.8%, and the efficiency of 17.1% without surface texturing.


► B and P ions were implanted and annealed on the n- and p-type Si, respectively.
► Diode properties of B-implanted samples improved with annealing temperature.
► But, diode properties of P-implanted samples degraded with annealing temperature.
► Implied Voc of the lifetime samples also followed the trend of the diode samples.
► Efficiency of the implanted back contact solar cell was 17.1% without texturing.
