Abstract
【解決手段】太陽電池11の受光面のメイングリッド電極4の形成に用いる銀ペースト中の銀の含有率を、サブグリッド電極5の形成に用いられる銀ペースト中の銀の含有率より低くする。
【選択図】図1
Description
これらの実施例では、メイングリッド電極4に銀含有率とガラスフリット含有率を変えた銀ペーストを用いて検討した。サブグリッド電極5には前記の通りペーストAを使用した。また、基準として、メイングリッド電極にもペーストAを使用した太陽電池も作製した。
これらの実施例及び比較例では、メイングリッド電極4に銀含有率とガラスフリット軟化点を変えた銀ペーストを用いて検討した。サブグリッド電極5には前記の通りペーストAを使用した。
これらの実施例及び比較例では、メイングリッド電極4は銀含有率と銀粉のBET値を変えた銀ペーストを用いて検討した。サブグリッド電極5には前記の通りペーストAを使用した。
これらの実施例及び比較例では、性能を落とすことなくメイングリッド電極4を薄くすることを試みた。メイングリッド電極4を薄くすれば、さらに銀使用量を削減できるためである。サブグリッド電極5はペーストAを使用し、前述の80μmの線幅のスクリーンで印刷し、平均厚を約15μmとなるよう形成した。メイングリッド電極4は前記実施例1の銀ペーストを使用し、スクリーン仕様を変えることで厚さを4種類に変化させて、実施例3つ及び比較例1つを作製した。メイングリッド電極4の厚さはメイングリッド電極4の中心部の平坦部分を1本当たり3点測定し、その平均値を厚さとした。
