CRYSTAL SILICON SOLAR CELL PREVENTING GENERATION OF DARK AREA DUE TO BREAKING OF ELECTRODE GATE LINES

摘要

PROBLEM TO BE SOLVED: To provide a crystal silicon solar cell that can ameliorate loss of electric performance due to gate break, allows finer gate lines to be designed, has a simple structure and is easily materialized.SOLUTION: An embodiment comprises a silicon chip body 1. On a surface of the silicon chip body 1, a plurality of main gate lines 2 are formed in the longitudinal direction; a plurality of fine gate lines 3 are formed in the transverse direction to electrically connect to the main gate lines 2; and a plurality of second gate lines 4 are provided to electrically connect the fine gate lines 3.
