BACK ELECTRODE TYPE SOLAR BATTERY CELL, WIRING SHEET, SOLAR BATTERY CELL WITH THE WIRING SHEET, AND SOLAR BATTERY MODULE

摘要

PROBLEM TO BE SOLVED: To provide a back electrode type solar battery cell and a wiring sheet that suppress decreases in reliability of a solar battery cell with the wiring sheet and a solar battery module, and also to provide the solar battery cell with the wiring sheet and the solar battery module that use the same.

SOLUTION: The invention relates to: the back electrode type solar battery cell such that ends of at least one of an electrode for a first conductivity type, and an electrode for a second conductivity type are narrower in width than at least a partial region from an end in a first direction to a center side; the wiring sheet such that ends of at least one of wiring for the first conductivity type and wiring for the second conductivity type are wider in width than at least the partial region from an end in the first direction to a center side; and the solar battery cell with the wiring sheet and the solar battery module that include at least one of them.
