A TRANSITION TO THINNER SI WAFERS AT HJT MASS PRODUCTION: AHEAD OF ITRPV SCHEDULE

摘要

Si wafer price constitutes ca. 50% of the solar cell production costs resulting in a global trend in Si solar cell and module industry towards application of thinner as-cut wafers. In this paper, we report a full transition of Hevel HJT module production to 150 um as-cut wafers 4 years ahead of predicted ITRPV schedule. We also update the current technological status of Hevel production.
