THIN FILM SOLAR BATTERY MODULE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To satisfy both appearance and reliability by discretely arranging photovoltaic thin film semiconductor layer in the longitudinal direction in a center part on the width side of a bus area and filling the hole with adhesive conductor. SOLUTION: SiO2 is formed on a transparent insulating substrate 1 and a transparent electrode layer 16 is formed on it. Grooves 18 are installed in the transparent electrode layer 16 by a laser work method. Strip individual region 17 are formed and a semiconductor layer 19 is formed on them. A rear electrode layer 22 is formed on the semiconductor layer 19 and the rear electrode layer 22 is made into individual electrodes 23 by grooves 24. Unit elements 28 across a semiconductor are connected in series between the transparent electrode and the rear electrode. Bus areas 3 and 3' are installed on both ends to which the elements 28 are connected. The plural discrete holes 29 are installed in the regions 3 and 3' and the holes 29 are filled with adhesive conductors.
