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
