Frederieke Kersten states: "Using the ALD compared with our MW-PECVD system creates a higher efficiency and is a promising tool for Al2O3 passivation."

"In our semiconductor affiliation program at imec we have been using ALD for many years," Program Director PV Jef Poortmans states. "Especially when a certain layer needs to be very dense, uniform and conformal, the ALD technique is a unique option."

"ALD Al2O3 provides excellent passivation to the rear surface of mono-Si and multi-Si solar cells," R&D director Fandang Jiang says. "At Jinko Solar, we can gain 1% efficiency on mono-Si and 0.6-0.8% efficiency on multi-Si. Also, the uniform thin AlOx layer grown by ALD is useful for front side passivation on n-type cells."
SoLayTec integration team
If customers don't have their own R&D team to make PERC process possible, SoLayTec can provide an on-site integration team for successful PERC integration. Our team has integrated PERC multi and mono for different customers in Asia on several occasions. A example is the following case.
