The colors are used to indicate the increase in speed. It is easier to distinguish and last silicon wafer. This result leads us to v ary the wafers
Monitoring the evolution of bromine element distribution reveals that the insert layer can efficiently suppress ion diffusion between perovskite films, even under long-term illumination and heating conditions.
However, the solar cells produced using the newly developed diffusion process demonstrated significant advantages in terms of open-circuit voltage and current, although there was a slight decrease in the fill factor. Moreover, a notable improvement in photovoltaic conversion efficiency was observed.
Employing this optimized diffusion process leads to a 0.05 % increase in the efficiency of PERC solar cells, a 1.3 mV increase in open-circuit voltage, and a 20 mA increase in short-circuit current. The peak cell efficiency attained is 23.68 %, marking a 0.16 % improvement.
In addition to in-situ doping or ion implantation, conventional thermal diffusion can be used to dope the polysilicon , with the added advantage of being a well-established process in the solar cell industry.
