6 FAQs about [Perc component cost]
How much does PERC cell processing cost?
Our calculation estimates that the cell processing cost of Al-BSF cells is presently 5.9 $-cents/Wp, while that of PERC cells is 7.1 $-cents/Wp. PERC cell processing requires two additional steps: First, rear side passivation by a ~15-nm thin film of AlOx followed by a ~70-nm thin film of SiNx, and, second, its local opening using laser ablation.
What is PERC technology?
The PERC technology has demonstrated higher cell efficiency (~19.3% stabilized ) than the Al-BSF technology and has the potential to become the mainstream cell technology in the PV industry. In fact, the ITRPV-16 predicts that by 2020 the PERC technology will have captured ~40% of the global solar cell market.
Will PERC capture 40 percent of the global solar cell market?
In fact, the ITRPV-16 predicts that by 2020 the PERC technology will have captured ~40% of the global solar cell market. However, to do so, PERC cell manufacturing needs to be economically competitive in terms of $/Wp compared with Al-BSF cell manufacturing.
Are PERC cells more efficient than Topcon cells?
With continuous refinements in design and manufacturing processes, TOPCon cells are inching closer to the theoretical efficiency limits of silicon solar cells. PERC cells, having been a cornerstone of the solar industry for a while, have a well-established efficiency track record.
How does a PERC cell work?
Rear Contact Design: The rear contact of a PERC cell is not just a conduit for extracting charge; it’s an integral part of the cell’s light-trapping mechanism. By reflecting unabsorbed light back into the active regions of the cell, it plays a pivotal role in the cell’s enhanced performance.
Why do PERC cells cost more than BSF cells?
Our calculations indicate that cost to manufacture p -type multi-Si PERC cells is ~0.7 $-cents/W p higher than p -type multi-Si BSF cells. The increase in cost is primarily due to additional processing steps requiring higher capital and labor cost, but partially compensated by the lower $/W p costs of the wafers and the silver.
