Document Type and Number:
WIPO Patent Application WO/2017/111697
Kind Code:
A1
Abstract:
A method of fabricating a heterojunction all-back-contact (ABC) solar cell, the method comprising the steps of: forming an emitter film on one side of a doped substrate; forming a conductive interlayer on the deposited emitter film; forming at least one channel, the channel cutting through at least the emitter film and the conductive interlayer; forming a continuous back surface field film on the deposited conductive interlayer and the channel formed; and forming a plurality of metallic grids on the deposited back surface field film, wherein at least a portion of at least one of the plurality of metallic grids is formed in the channel.
