Features and Quality Control
Each of our solar cells features silicon nitride antireflection coatings which are deposited using plasma-enhanced chemical vapor deposition process
Cells have state-of-the-art silver front contacts, silver-aluminium back contact strips, and full-coverge aluminium back contacts with back surface field
Metal pastes are screen printed in a fully automated process
100% checked for visual appearance, pre-degraded before measuring electrical performance
Classified the grades by cell efficiency, work current and reverse current
Frequent reliability monitoring
Our Commitment to Quality
We are ISO 9001 and 14000 certified
Color uniformity among cells and within cells
Low overall breakage rate
Low warpage and bowing
Long-term stability & reliability
Small light-induced degradation
