p> The rate at which diffusion occurs depends on the velocity at which carriers move and on the distance between scattering events. It is termed diffusivity and is measured in cm 2 s -1. Values for silicon, the most used semiconductor material for solar cells, are given in the appendix.
Conclusion In this study, the diffusion process for PERC non-selective emitter solar cells is refined. The modified diffusion protocol includes two added stages: pressure holding and extended annealing time.
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.
Values for silicon, the most used semiconductor material for solar cells, are given in the appendix. Since raising the temperature will increase the thermal velocity of the carriers, diffusion occurs faster at higher temperatures. A single particle in a box will eventually be found at any random location in the box.
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.
Although the front-side phosphorus diffusion method for creating P-type PERC cells is well researched, avenues for innovation persist. We introduce a P–N junction fabrication technique for PERC solar cells via precisely controlling the surface doping concentration and junction depth.
