実施例1では、図1(4−b)に示す断面の光電変換素子81を、図1(4−a)のように支持基板1上に6つ作製し、それぞれの性能を確認した。また、アニール処理工程S5で加熱温度による性能の変化を確認するため、7つの支持基板1の上に加熱温度の設定だけを変えて光電変換素子81を作製した。設定した加熱温度は25℃、40℃、50℃、100℃、150℃、160℃、170℃である。
実施例2では、工程S3−3の塗布した有機半導体溶液を一定時間加熱して乾燥させる第3工程と工程S5のアニール処理工程を窒素雰囲気下で行った。また、工程S5のアニール処理工程で設定した加熱温度は100℃だけである。
実施例3では、工程S3−1の溶媒に有機半導体材料を溶解または分散させ有機半導体溶液を作製する第1工程において、次の材料を用いる。すなわち、電子受容性有機材料としてPCBIB(Pheny C61−butyric acid i−butyl ester:フロンティアカーボン社製)、電子供与性有機材料としてMEH−PPV(poly[2−methoxy−5−(2′−ethylhexyloxy)−p−phenylene vinylene]:アルドリッチ社製)を用いた。
比較例1では、工程S5の効果を確認するため工程S5のアニール処理工程を省いた。
比較例2では、工程S3−1の溶媒に有機半導体材料を溶解または分散させ有機半導体溶液を作製する第1工程、工程S3−2の有機半導体溶液を塗布する第2工程、工程S3−3・・・塗布した有機半導体溶液を一定時間加熱して乾燥させる第3工程と、工程S5のアニール処理工程を窒素雰囲気下で行った。
このようにして作製した実施例1〜3、比較例1、2の光電変換素子81を以下の条件で測定した。
光入射面は図1(4−b)に矢印Lで示す面である。
