摘要: Provided are a solar battery cell, and junction structure therefor, in which back contact type cell reduction recombination loss of carriers occurring solder connection results improved power generation efficiency. The is provided with silicon substrate (112); pairs finger electrodes (114p) (114n) formed on first surface (113) the connected respectively to P-type diffusion layer (117) an N-type (118); internal passivation layers (115) that insulate between electrodes; area (102) for externally connecting cluster section where sections one group together; and, area, barrier (101) tips other have different polarity from area.
