Monday, 17 Oct 2022
This is the second part on PECVD production equipment suppliers for HJT solar cell processing, which follows on article published last week that covered Chinese suppliers (see The Supply Side Of PECVD Tools For HJT – Part 1).
One Coat, Two Functions
Balancing Between Passivation And Optical Properties Is The Key For PECVD SiNx Deposition Tools
Wednesday, 14 Sep 2022
PECVD tools have been the work horse for application silicon nitride film applied on the emitter of the p-type solar cells since the past BSF days to the current PERC.
Two-In-One With PECVD
PECVD Come With An Inherent Advantage Of Depositing Aluminium Oxide On Solar Cells As Well As The Capping Silicon Nitride In One Go
Tuesday, 06 Sep 2022
As part of our PERC Solar Cell Production 2022 report, we also looked into passivation tools. PECVD is one of the two mainstream methods employed to deposit aluminium oxide used as the rear passivation dielectric in PERC structure.
No Wrap-Around With PECVD
Several PV Equipment Makers Working on PECVD Tools For TOPCon Solar Cell Production
Wednesday, 02 Mar 2022
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
Sunday, 07 Feb 2021
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
Tuesday, 19 Jan 2021
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
Monday, 11 May 2020
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.
