Description
色素増感太陽電池の心臓部である色素において、現在一般に用いられているのは希少金属を用いるルテニウム錯体色素であるが、これは、光電変換効率・耐久性に優れてはいるものの、希少金属であるゆえに、色素増感太陽電池の実用化のための色素の安定供給に疑問がある。かたや希少金属を全く使用しないメタルフリーな有機色素において、ここ10年で様々な有機色素化合物が開発され、その性能が飛躍的に向上してはいるものの、光電変換効率および耐久性についてはルテニウム色素に及ばないのが現状である。中でも有望視されている有機色素は、カルバゾール系有機色素(特許文献1、非特許文献1、非特許文献2)やインドリン系有機色素(三菱製紙株式会社・ケミクレア株式会社等から市販:製品名D149)(特許文献2)である。
また、最近では電解液に含まれるレドックス種としてコバルト錯体レドックスを用いた色素増感太陽電池の開発研究が盛んに行われている。コバルト錯体レドックスのレドックスポテンシャルは、一般に使用されているヨウ素レドックスと比べて深く、理論的には高い開放電圧が期待できる。しかしながら、酸化チタン中に注入された電子のコバルト錯体レドックスへの再結合反応がヨウ素レドックスの場合に比べて非常に速く、期待通りの開放電圧を得ることが難しい(非特許文献3)。すなわち、使用する増感色素に電荷再結合反応を抑制する機能を付与することが求められる。それゆえ、構造変換が比較的容易な有機色素を用いてコバルト錯体レドックス系色素増感太陽電池に適した色素開発が行われてきた(非特許文献4)。また、中には高開放電圧を与える有機色素が開発されているが、用いられているドナー構造の特徴により、π電子伝達部位を拡張することが難しく、光電変換に使用できる光波長領域が限られるといった問題点があった(非特許文献5)。
我々は、これまでにカルバゾール系有機色素を用いてコバルト錯体レドックス系色素増感太陽電池の高効率化の研究を行ってきた。有機色素の立体障害が大きくなるような置換基を組み込み、さらに色素吸着密度を向上させる工夫をすることにより、開放電圧向上の道筋を模索してきた(非特許文献6)。しかしながら、ヨウ素系電解液を使用した場合に比べて、酸化チタン中の電子寿命は短く、未だに期待される開放電圧は得られておらず、それゆえ光電変換効率もそれほど向上しなかった。

(1)有機色素吸着酸化チタン薄膜ガラス電極の作製
チタン・テトライソプロポキシドの加水分解により作製した酸化チタンコロイドをオートクレービングすることにより結晶性の酸化チタンナノ粒子を得た。これに、バインダーとしてエチルセルロース、溶媒としてα−テルピネオールを混合した有機性のペーストを作製した。あるいは、市販の酸化チタンペースト(たとえば、Solaronix社製)を用いても良い。上記酸化チタンペーストをスクリーン印刷法により、フッ素ドープ酸化スズコート導電性ガラス上もしくは酸化スズコート導電性ガラス上に塗布し、空気中450℃−500℃で30分〜2時間焼成することにより、膜厚が3〜20ミクロンの酸化チタン薄膜電極を得た。この電極を、0.1mM〜0.3mMの有機色素溶液(溶媒は、トルエン、もしくはアセトニトリル、t‐ブチルアルコールの混合溶媒)に浸漬し、室温で10時間以上放置することにより、有機色素吸着酸化チタン薄膜電極を得た。
前記(1)で作製した酸化チタン薄膜電極(膜厚4ミクロン)に表1記載の色素を吸着させ、白金を担持した酸化スズコート導電性ガラスを対極として、ポリエチレンフィルムスペーサーを挟んで熱圧着させ、その隙間に電解液である0.22mコバルト(II)ビピリジルテトラシアノボレート、0.02Mコバルト(III)ビピリジルテトラシアノボレート、0.1M過塩素酸リチウム、0.2M t-ブチルピリジンのアセトニトリル溶液を注入し、セルを作製した。セルの光電変換特性の測定は、光源としてキセノンランプとエアマスフィルター(AM 1.5G)からなるソーラーシミュレーターを用い、光電流電圧特性は、ソースメーターを用いて測定した。
