Does the thickness of sin x affect the efficiency of PERC solar cells?

With the increasing thickness of SiN x on the front surface, there will be a significant decrease in the efficiency of PERC solar cells. Fig. 8. Thickness importance ranking of PERC solar cells obtained from SHAP value. 4. Conclusion

How efficient are PERC solar cells?

Nowadays, industrially produced crystalline silicon (c-Si) PERC solar cells are typically in the thickness of 170–180 μm and have an average cell efficiency of 22% at this stage, but there has been continued research into how to further improve cell efficiency for the PERC cells with standard thickness [, , ].

Can PERC solar cells be thinned without design?

The reduction of silicon wafer thickness can significantly save the costs, but there is a loss of cell efficiency if cell design is not conducted. For the thinned 100 μm-thickness PERC solar cells without design, the efficiency loss is pronounced from commercial 180 μm-thickness.

What is the surface coating for p-type PERC solar cells?

In this paper, a gradient-designed capping layer consisting of silicon nitride/silicon oxynitride/silicon oxide (SiN x /SiN x O y /SiO x) is proposed as the surface coating for p-type PERC solar cells. The capping layer improves the short wavelength spectral response due to its better anti-reflection effect.

Can crystalline silicon PERC solar cells save the cost?

Conclusion The remarkable reduction in thickness of crystalline silicon PERC solar cells can significantly save the cost, but a loss of cell efficiency is suffered. For the 100 μm-thickness thin PERC solar cells without design, the efficiency loss is even more pronounced.

How efficient are double-sided textured PERC solar cells?

Furthermore, the efficiency of the double-sided textured PERC solar cells is improved to 22.9%, which causes an absolute efficiency gain of 1.3% compared with the reference cell.
