Abstract
【解決手段】薄膜太陽電池10において、絶縁性基板11の表面側及び裏面側の各層(第一電極層12、光電変換層13、第二電極層14、第三電極層16、第四電極層17)を線状に除去して分割することによって単位太陽電池(UC)が複数形成され、これらは複数の集電孔19及び接続孔20を介して直列接続されている。絶縁性基板11の表面側の各層を線状に除去する第1線状除去部21及び絶縁性基板の裏面側の各層を線状に除去する第二線状除去部22の少なくとも一方が屈曲部を有して形成され、複数の集電孔19は各単位太陽電池(UC)の第二電極層14全体にわたって分散配置されている。
【選択図】図1
Description
まず、図10(a)に示すように、絶縁性基板71の所定位置に、複数の接続孔80を形成する。絶縁性基板71としては、例えば、ポリイミド系、ポリエチレンナフタレート(PEN)系、ポリエーテルサルフォン(PES)系、ポリエチレンテレフタレート(PET)系又はアラミド系のフィルムを用いることができる。接続孔80は円形であり、その直径は1mmのオーダーである。接続孔80は、パンチ等の機械的手段で形成することができる。
図1は、本発明の第一実施形態による薄膜太陽電池10の平面図である。薄膜太陽電池10はSCAF構造を有しており、その基本的な構成は、図9,図10に示された従来の薄膜太陽電池70と同じである。すなわち、薄膜太陽電池10は、可撓性を有する絶縁性基板11を備える。絶縁性基板11の表面側には、第一電極層12,光変換層13及び第二電極層14が順に積層された光電変換部15が設けられ、絶縁性基板11の裏面側には第三電極層16及び第四電極層17が順に積層された裏面電極層18が設けられている。
絶縁性基板11を構成するプラスチック基板としては、例えば、ポリイミド系、ポリエチレンナフタレート(PEN)系、ポリエーテルサルフォン(PES)系、ポリエチレンテレフタレート(PET)系又はアラミド系のフィルムを用いることができる。なお、可撓性を必要としない場合には、ガラス基板等を用いてもよい。
ここで、従来の薄膜太陽電池(図9参照)と対比しつつ、本実施形態による薄膜太陽電池10の特徴のうちのいくつかを説明する。
