Abstract
Description
本発明を具体的に説明する前に、概要を述べる。本発明の実施例1は、複数の太陽電池セルがマトリックス状に配置された太陽電池モジュールに関する。太陽電池モジュールでは、第1保護部材と第2保護部材との間に封止部材が配置され、封止部材によって複数の太陽電池セルが封止される。その際、隣接した2つの太陽電池セルは、ワイヤフィルムによって接続される。ワイヤフィルムは、前述のごとく、2つの透明部材が複数のワイヤによって接続されており、各透明部材が隣接の太陽電池セルに貼り付けられる。ワイヤが配線材の役割を有するので、ワイヤが延びる方向に配置された複数の太陽電池セルを複数のワイヤフィルムで接続することによってストリングが形成される。このようなワイヤフィルムは、太陽電池モジュールの製造を簡易にするために使用される。一方、太陽電池セル上の集電極が銀ペーストで形成され、ワイヤの表面が低融点半田でコートされている場合、集電極とワイヤとの接着力が低くなる。接着力が低い場合、温度の上昇および下降を繰り返す温度サイクル試験を実行すると、ワイヤが太陽電池セルからはがれてしまうおそれがある。
x−a=r−√(r2−b2)
次に、実施例2を説明する。実施例2は、実施例1と同様に、樹脂フィルムを太陽電池セルに貼り付けることによって形成したストリングを含む太陽電池モジュールに関する。実施例1では、第1交差領域であるか第2交差領域であるかにかかわらず第1種配線材の形状は同一である。一方、実施例2では、第1交差領域であるか第2交差領域であるかに応じて第1種配線材の形状が異なる。実施例2に係る太陽電池モジュール100は、図1、図2と同様のタイプであり、樹脂シート80は、図3と同様のタイプであり、太陽電池セル10は、図4(a)−(b)と同様のタイプである。ここでは、これまでとの差異を中心に説明する。
