Description
本願は、2008年3月31日に出願された特願2008−090567号に基づき優先権を主張し、その内容をここに援用する。
このような上下電極と半導体膜からなる光電変換体を備えたアモルファスシリコン太陽電池においては、基板上に広い面積で均一に各層を成膜しただけでは電位差が小さく、抵抗値が大きくなる問題がある。そのため、例えば、光電変換体を所定のサイズごとに電気的に区画した区画素子を形成し、互いに隣接する区画素子どうしを電気的に接続することにより、アモルファスシリコン太陽電池が構成されている。
具体的には、基板上に広い面積で均一に形成した光電変換体にレーザー光などを用いてスクライブ線(スクライブライン)と称される溝を形成し、多数の短冊状の区画素子を得て、この区画素子どうしを電気的に直列に接続した構造が採用される。
また、欠陥箇所が発熱する程度にバイアス電圧を印加するため、半導体膜にダメージを与える虞もあった。
光を照射して区画素子ごとのFFを測定する方法では、欠陥が存在する区画素子自体は検出できるが、区画素子内のどこに欠陥が存在するかを特定することは困難であった。
また、大よその欠陥位置しか特定しないで、バイアス電圧を印加して欠陥を除去する場合、バイアス電圧を高くする必要があった。しかし、必要以上に高いバイアス電圧を印加すると、欠陥が生じていない正常な部分にダメージを与えるという問題があった。
本発明の第1態様の太陽電池の製造方法においては、前記構造欠陥が存在する部位を限定する際(欠陥部位特定工程)に、抵抗値の測定には4探針式の抵抗測定装置が用いられることが好ましい。
即ち、本発明の第2態様の太陽電池の製造装置は、複数の区画素子を含む光電変換体を有する太陽電池の製造装置であって、前記光電変換体のうち、構造欠陥を有する前記区画素子内で構造欠陥が存在する部位を限定するために、互いに隣接する前記区画素子どうしの間で複数個所の抵抗値を測定する抵抗測定部を含む。
11 基板
12 光電変換体
13 第一電極
14 半導体層
15 第二電極
19 スクライブ線
21 区画素子
まず、図1に示すように、透明な基板11の第1面11aに上に光電変換体12を形成する(光電変換体の形成工程:P1)。光電変換体12の構造としては、例えば、基板11の第1面11aから順に第一電極層(下部電極)13,半導体層14,及び第二電極層(上部電極)15が積層された構造であればよい。
この修復工程において、欠陥部位特定工程で欠陥の区画素子内での正確な存在位置が特定されているため、構造欠陥Rを含む最小限の範囲E1からE3だけを除去することができる。即ち、図4(a)に示す構造欠陥A1からA3の各々は、図4(b)の符号E1からE3に示すように除去される。
一方、欠陥修復時には点線で示す回路に切り替えて、抵抗測定用のバイアス電流W1よりも高い電圧の欠陥修復用のバイアス電流W2を探針B1から供給し、欠陥を含む部位を除去(修復)する。
