  • METHOD FOR PRODUCING REAR SURFACE CONTACT SOLAR CELLS FROM CRYSTALLINE SILICON
    Publication number: 20190348560
    Abstract: A back surface contact solar cell has a wafer with an anti-reflection layer on the front surface, with an emitter and a back surface field on the back surface, and with contacts, produced using laser ablation, on the back surface, wherein the pitch is at most 800 micrometers. Furthermore provided is a method for producing such a solar cell.
