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.
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.
Constraints on Wafer Size for HJT
While HJT Not Only Requires Superior Quality N-Type Wafers Compared to P-Type Based Peers, The Technology is Not Yet Ready To Embrace Real Large Wafers
It is well known that HJT requires a completely different fab setup and process sequence. The change in fact starts at the wafer level.
