HETEROJUNCTION BACK CONTACT SOLAR CELL AND METHOD FOR MANUFACTURING SAME

摘要

This method for manufacturing a heterojunction back contact cell comprises: a step for forming a dielectric film (6) so as to be in contact with a first surface (1a) of a semiconductor substrate (1), said dielectric film (6) containing nitrogen and silicon; a step for forming an amorphous semiconductor film (3) of a first conductivity type and an amorphous semiconductor film (5) of a second conductivity type on a second surface (1b) of the semiconductor substrate (1), said second surface (1b) being on the reverse side of the first surface (1a); a step for forming a first electrode (7) on the amorphous semiconductor film (3) of a first conductivity type; and a step for forming a second electrode (8) on the amorphous semiconductor film (5) of a second conductivity type.
