実施例1の有機薄膜太陽電池は、以下のようにして作製した。まず、透明基板として、125μmのポリエチレンナナフタレート(PEN)準備し、このフィルム上に、表面抵抗(シート抵抗)が15Ω/□となるようにインジウムスズ酸化物(ITO)膜を積層し、4cm×4cmのサイズに切り出した透明導電性フィルムを作製した。
実施例2の有機薄膜太陽電池が、実施例1と異なる点は、光電変換層の乾燥後の厚さを約200nmとしたことと、酸化珪素含有光電変換層の形成に用いた材料のみであり、その他の条件および方法は、実施例1と全く同様にして、実施例2の有機薄膜太陽電池を作製した。酸化珪素含有光電変換層を形成する材料として、実施例1では、PHPS濃度0.005wt%のPHPSとP3HTとPCBMとの混合キシレン溶液を用いたが、実施例2では、混合溶液ではなく濃度0.005wt%のPHPSキシレン溶液を用いた。
比較例1の有機薄膜太陽電池が、実施例1と異なる点は、光電変換層の乾燥後の厚さを約200nmとしたことと、酸化珪素含有光電変換層を形成していない点のみであり、その他の条件および方法は、実施例1と全く同様にして、比較例1の有機薄膜太陽電池を作製した。
比較例2の有機薄膜太陽電池が、実施例1と異なる点は、光電変換層および酸化珪素含有光電変換層であり、その他の条件および方法は、実施例1と全く同様にして、比較例2の有機薄膜太陽電池を作製した。実施例1では、P3HTとPCBMの混合溶液を用いて光電変換層を形成し、この光電変換層の上に、PHPS濃度0.005wt%のPHPSとP3HTとPCBMとの混合キシレン溶液を用いて酸化珪素含有光電変換層を形成したが、比較例2では、実施例1の酸化珪素含有光電変換層の形成に用いた、PHPS濃度0.005wt%のPHPSとP3HTとPCBMとの混合キシレン溶液を用いて、層全体を酸化珪素含有光電変換層とした乾燥後の厚さが約200nmの光電変換層を形成した。
