Description
図1は、本発明の実施の形態1にかかる太陽電池セルの製造工程の一例を説明するためのフローチャートである。図2−1〜図2−9は、本発明の実施の形態1にかかる太陽電池セルの製造工程の一例を説明するための要部断面図である。図3は、実施の形態1にかかる太陽電池セルの製造方法により作製された実施の形態1にかかる太陽電池セルの概略構成を示す要部斜視図である。なお、図1および以下の説明においては記載していないが、各工程間には必要に応じて、ウェハ洗浄処理、自然酸化膜除去を目的としたフッ酸への浸漬処理、水洗処理を行っている。
図8は、本発明の実施の形態2にかかる太陽電池セルの製造工程の一例を説明するためのフローチャートである。実施の形態1においてはレーザ照射後にリンガラスを除去する場合について説明したが、レーザ照射とリンガラスの除去との順序はこれに限定されない。レーザ照射とリンガラスの除去との順序が逆、すなわち、リンガラスを除去した後にレーザ照射を行ってもかまわない。
