SiNx Deposition Systems For Silicon Nitride Deposition
Deposition Tools For Silicon Nitride Film Application In Semiconductor And Solar Cell Manufacturing
The PECVD tools promoted for aluminum oxide deposition are not too different to the ones used for silicon nitride. In fact, the former tools were derived from the latter by changing the precursor supply system and cleaning mechanism.
PECVD Systems For Aluminum Oxide Deposition
PECVD Systems Streamline Alox Deposition By Adding A Sinx Capping Layer Within A Single Vacuum, Optimizing PERC Solar Cell Rear Passivation
TaiyangNews recent market survey on cell production survey features tools from various equipment suppliers; in our previous article published on this topic we provided details for ALD Systems For Aluminum Oxide Deposition.
HJT Processing: Shifting To Micro Silicon Layers
The Introduction Of A Microcrystalline Silicon Layer Into The HJT Structure Is The Key Development In The Core Layer Deposition Step
When wafers enter the core layer deposition stage, it means they reach the heart of HJT processing. This stop follows wet etching, which we discussed in a separate article (see Cleaning Has Big Role In HJT).
Semco Smartech Speaks on Current TOPCon Cell Manufacturing Trends
Semco Smartech CEO Raymond De Munnik Presented Manufacturing Trends and Cost Comparisons for TOPCon cells
During the TaiyangNews Virtual Conference on High Efficiency Solar Technologies 2022 – TOPCon, HJT and Beyond, Today & Tomorrow, Raymond De Munnik, CEO SEMCO Smartech emphasized that TOPCon is a mature technology already in 2022, with a ‘big cell line installation boom’ going on.
PECVD Based Solution For Polysilicon in TOPCon Cells
Video: Boachen Liao From China’s Lead Micro Talks About PECVD Based Solution For Polysilicon Layer In TOPCon Mass Production at TaiyangNews Event
During the TaiyangNews Virtual Conference on High Efficiency Solar Technologies 2022 – TOPCon, HJT and Beyond, Today & Tomorrow, Lead Micro’s Chief Scientist, Prof. Boachen Liao represented the equipment production side at the event.
The Supply Side Of PECVD Tools For HJT – Part 2
While Our Previous HJT PECVD Article Covered Tool Suppliers Manly From China, There Are Few More, And Also Offering Other Technologies
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).
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
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
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.
