TCO Deposition: First Foreign, Increasingly Local
Majority Of HJT Cell Makers Opted For Western TCO Deposition In First Lines And Increasingly For Domestic Tools For Later Expansions
In an earlier article we discussed the basics of the technologies for applying in HJT solar cell production the transparent conductive oxide (TCO) layer, which acts as both an antireflective coating and a conductive electrode to extract and laterally.
The Wafers Side Of HJT
HJT Is Increasingly Ready For Larger G12 Wafer Formats As Manufactures Are Prepared To Process Half G12 Cells
While fewer, the number of steps for HJT cell processing are completely different from mainstream PERC with change requiring right at the wafer level. HJT typically uses n-type wafers, unlike today’s mainstream that relies on p-type base wafers.

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.
Reducing HJT Costs With CAT-CVD
JAIST Proposed A Gen-2 CAT-CVD Reactor Design, Which Has Potential To Bring Down The HJT Production Costs To The Level Of PERC
In HJT solar cell processing, while every step is important and ultimately contributes to the final cell performance, core layer deposition attracts the utmost attention.
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.
Pyramid Size Matters
In Wet-Chemical Processing of HJT Cells More Silicon is Etched Off the Surface During Saw Damage Removal Compared to Standard Cells & Pyramid Size Optimization is Focus in Texturing Part
Compared to standard solar cell processing, HJT requires a completely different manufacturing setup. However, the wet-chemical process is somewhat an exception, as the basic process steps remain the same – saw damage removal, texturing and cleaning.
