Title:
SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2012/090641
Kind Code:
A1
Abstract:
A solar cell with improved photoelectric conversion efficiency is provided. An electrode (11p) on the side of an other conductivity type has a plurality of finger electrode sections (12p) on the side of the other conductivity type and a bus bar section (13p) on the side of the other conductivity type that electrically connects the plurality of finger electrode sections (12p) on the side of the other conductivity type. An electrode (11n) on the side of one conductivity type has a plurality of comb-shaped electrode sections (14). Each of the plurality of comb-shaped electrode sections (14) has a plurality of one conductive side finger electrode sections (12n) on the side of the one conductivity type and a bus bar section (13n) on the side of the one conductivity type that electrically connects the plurality of finger electrode sections (12n) on the side of the one conductivity type. The plurality of finger electrode sections (12p) on the side of the other conductivity type include a finger electrode section (12p1) on the side of the other conductivity type, positioned between adjacent comb-shaped electrode sections (14) in a second direction (y). The end section of the finger electrode section (12p1) on the side of the other conductivity type is positioned between bus bar sections (13n) on the side of the one conductivity type in adjacent comb-shaped electrode sections (14).
