Features and Quality Control
Each of Econess’s 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
