"Solar Cell Manufacturing of Mono-crystalline Wafers with IPA Free Texturing"
Matt Moynihan - R&D Director, Dow Electronic Materials

PDF Presentation

ABSTRACT Silicon solar cell process engineering will be reviewed. Detailed chemical etching technology for wafer surface texturing will be presented, with improved integrity and desired pyramid structure. The new additive has been shown to improved the overall process stability with respect to etch rate and reflectance while generating comparable cell performance for both horizontal and vertical equipment configurations.
