Title
(EN) HIGH EFFICIENCY CONFIGURATION FOR SOLAR CELL STRING
(JA) 太陽電池列のための高効率構成
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an arrangement and configuration of a solar cell string capable of realizing high conversion efficiency.

SOLUTION: For each pair of solar cells 10, a solar cell string is formed with a roof-shingling connection where a bottom contact pad 30 of one solar cell 10 overlaps a front surface bus bar 15 of the other solar cell 10. An exposed front surface bus bar 15 at one end of the string and an exposed bottom contact pad 30 at the other end of the string may be used to electrically connect the string to other electrical components as desired.
