No Wrap-Around With PECVD
Several PV Equipment Makers Working on PECVD Tools For TOPCon Solar Cell Production
Addressing the shortcomings of LPCVD equipment for the production of TOPCon solar cells, as discussed in our earlier article (see LPCVD for TOPCon Cells), especially the wraparound, the PV industry is increasingly getting interested in PECVD technology.
Suppliers Of Core Layer Deposition Tools For HJT
While One Leading PECVD Supplier Exited From The Open Market, Several Chinese Companies Are Foraying Into Core Layer Deposition Tools For HJT Solar Cells
PECVD is more or less the current state of the art in the regular equipment stream for core layer deposition of heterojunction (HJT) solar cells.
The Core Of HJT
While PECVD Is The Widely Followed Technology For Applying Core Layer In HJT, CAT-CVD Was Also In Use And PEALD Is In Development
Core layer depositions the heart of HJT processing. It involves multi-layer stacking of intrinsic-amorphous and doped-amorphous silicon layers of opposite polarities on each side of the wafer and controlling them at the nanometer scale.
How Much to Put Down the Rear Deposit On PERC Cells?
Thickness Of Aluminum Oxide Film And Precursor TMA Consumption Varies As Per Deposition Technology & Changes With Equipment
The two mainstream manufacturing technologies that are currently available for application of the rear passivation stack of PERC cells are ALD and PECVD. In fact, the method of deposition affects the thickness of the deposition.
Universal PERC Tool From Meyer Burger
Swiss PV Production Equipment Maker Introduces Platform To Address All Passivation Needs Of PERC Cell Lines With One Tool
As part of PERC processing, Plasma Enhanced Chemical Vapor Deposition (PECVD) has an undeniable advantage of depositing aluminum oxide and silicon nitride capping layer simultaneously in one system.
