THIN-FILM SOLAR CELL AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To avoid degradation of characteristics even if multiple open grooves for natural illumination are provided. SOLUTION: A plurality of natural-illumination open grooves 7 are formed extending in the direction orthogonal to such direction as solar cell pieces 6 are connected in series. Along with formation of the natural-illumination open grooves 7, a battery cell train 8 in which the solar cell pieces 6 are connected in series is formed between the natural-illumination open grooves 7. Both ends of the battery cell train 8 are connected to respective power terminals 9 while the power of each battery cell train 8 is led through the power terminal 9 and a wiring cord 11, so a current path is short with less resistance loss.
