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.
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.
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.
The modified diffusion protocol includes two added stages: pressure holding and extended annealing time. These additions aim to elevate the sheet resistance while enhancing the diffusion resistance and intra-wafer uniformity, ultimately augmenting the solar cell photovoltaic conversion efficiency.
Temperature notably affects junction depth and surface concentration, and thus, by refining the diffusion process temperature, it is possible to fabricate P–N junctions with lower surface phosphorus concentration and deeper junction depth [, , ], thereby further enhancing the photovoltaic conversion efficiency.
