Abstract
Description
図1は、本発明にかかる太陽電池の製造方法の実施の形態1のステップフローを示す図、図2は、同ステップフローで形成された太陽電池を示す図、図3−1〜図3−8は同太陽電池の製造工程を示す工程断面図である。本実施の形態では、プロセスを簡略化した高効率セルの製造方法を提案する。先ず拡散源と、次工程の拡散保護マスクとして、片面に不純物を含む膜を形成する。次に片面に形成した膜中に含まれる不純物とは異なる不純物を拡散することにより受光面側と裏面で異なるドーパントの拡散層が形成されるため、一度の拡散処理で両面の拡散層が形成される。ここで、裏面の平坦化により高効率化が有効になる場合があるが、不純物を含む拡散保護マスクをテクスチャー処理前に形成することで、受光面のみにテクスチャー構造を形成できる。
図4は、本発明にかかる太陽電池の製造方法の実施の形態2のステップフローの要部を示す図、図5は、同ステップフローで形成された太陽電池を示す図、図6−1〜図6−9は同太陽電池の製造工程の要部を示す工程断面図である。本実施の形態では半導体基板として、n型単結晶シリコンウエハ1nを用いた場合の工程を説明する。表裏の拡散層形成工程までは、拡散する不純物のドナーとアクセプタを入れ替えれば、p型単結晶シリコンウエハと同様である。図6−5までは導電型が逆であるだけで図3−5までの工程と同様の図である。以降の図6−6から説明する。ここでは、受光面側にp型拡散層6pを形成すると共に、裏面側にn型拡散層4nを形成している。
図7は、本発明にかかる太陽電池の製造方法の実施の形態3のステップフローの要部を示す図、図8−1〜図8−3は同太陽電池の製造工程の要部を示す工程断面図である。本実施の形態では、実施の形態2と同様、n型単結晶シリコンウエハ1nを用いた場合で酸化膜形成工程を1回に省略する場合について説明する。ここでも、受光面側にp型拡散層6pを形成すると共に、裏面側にn型拡散層4nを形成している。
図9は、本発明にかかる太陽電池の製造方法の実施の形態4のステップフローの一部を示す図、図10−1〜図10−8は同太陽電池の製造工程を示す工程断面図である。本実施の形態では、実施の形態1において、テクスチャー形成のためのエッチングステップS102に先立ち裏面側に片面マスクを形成(S103)し、裏面側にテクスチャーが形成されるのを抑制したことを特徴とするものである。他は前記実施の形態1と同様である。
