有機薄膜光電変換素子のための水分散有機半導体コロイドを用いた 静電塗布(ESD)技術

摘要

Organic thin film photovoltaic devices were fabricated using a novel aqueous processing. An active layer of poly(3-hexyltniophene) (P3HT) was prepared by electrospray deposition (ESD) technique with P3HT colloidal particles dispersed in water. The performance of the photovoltaic device (ITO/P3HT/A1) was comparable to that of the device fabricated using typical spin-coating method. These results demonstrate that the novel aqueous processing is a good candidate for the manufacturing method of organic photovoltaic devices.%有機半導体材料ポリチォフェン(P3HT)をコロイド化して水溶性有機半導体インクを調製し，静電塗布(ESD)法でP3HT薄膜の形成を行い，単層型有機薄膜光電変換素子を作製した.この単層型素子において，光電流-電圧特性の測定などを行つたところ，従来のスピンコート法で作製した素子と同程度以上の性能が確認された.
