Description
図1は、本発明の第1実施形態にかかる光電変換素子モジュールを示す概略断面図である。
作用極11は、透明基材2の一方の面に設けられる透明導電体1から成る第2電極20と、透明導電体1上に設けられ、光増感色素が担持される多孔質酸化物半導体層3とを備える。
電解質5は、多孔質酸化物半導体層3内に電解液を含浸させてなるものか、または、多孔質酸化物半導体層3内に電解液を含浸させた後に、この電解液を適当なゲル化剤を用いてゲル化(擬固体化)して、多孔質酸化物半導体層3と一体に形成されてなるもの、あるいは、イオン性液体、酸化物半導体粒子若しくは導電性粒子を含むゲル状の電解質を用いることができる。
対極12は、第1電極10により構成される。第1電極は、チタンまたはチタン合金からなる金属板4と触媒層6とで構成される。なお、還元反応を促進する触媒層6は、金属板4における作用極11側の表面に形成される。触媒層6は、白金や炭素などからなる。
封止材14は、作用極11と対極12とを連結しており、作用極11と対極12との間の電解質5は、封止材14によって包囲されて封止される。封止材14を構成する材料としては、例えばアイオノマー、エチレン−ビニル酢酸無水物共重合体、エチレン−メタクリル酸共重合体、エチレン−ビニルアルコール共重合体、紫外線硬化樹脂、及び、ビニルアルコール重合体が挙げられる。なお、封止材14は樹脂のみで構成されてもよいし、樹脂と無機フィラーとで構成されていてもよい。
作用極11の第1電極側の表面における封止材14の外周で包囲される外側の領域において、透明導電体1上に端子8が形成される。端子8を構成する材料としては、金、銀、銅、白金、アルミニウムなどの金属が挙げられる。
次に、本発明の光電変換装置の第2実施形態について図2を用いて説明する。なお、図2において、第1実施形態と同一又は同等の構成要素については同一符号を付し、重複する説明を省略する。
次に、本発明の光電変換装置の第3実施形態について図3を用いて説明する。なお、図3において、第2実施形態と同一又は同等の構成要素については同一符号を付し、重複する説明を省略する。
次に、本発明の光電変換装置の第4実施形態について図4を用いて説明する。なお、図4において、第3実施形態と同一又は同等の構成要素については同一符号を付し、重複する説明を省略する。
