Description
図1は本発明の電極部材を用いた本発明の色素増感太陽電池の基本構成を示したものである。本発明の表面側電極部材は、基本的に特許文献1に開示されたと同様の基本構成をもつ色素増感太陽電池に適用できる。
まず、片面にフッ素ドープ酸化スズ(FTO)からなる厚み400nmの透明導電膜層を形成した30mm×30mm×2mmのガラス基板、あるいは片面に酸化インジウム(ITO)からなる厚み400nmの透明導電膜層を形成した30mm×30mm×0.1mmのポリエチレンテレフタレート樹脂(PET)の透明導電膜層の上に、下記の酸化チタンの微粒子群からなる層を、低温の高速フレーム溶射法により積層した場合の方法について説明する。
チタンの微粒子群からなる層の表面に吸着させて、表面側電極を得た。
作製した色素増感太陽電池は、100mW/cm2のソーラーシミュレータによる照射の下で、電流密度−電圧(FF)特性及び変換効率を測定することによりその特性を評価した。これら特性評価の測定結果は、溶射フレーム温度、フレーム速度及び皮膜の鉛筆引っかき強度、アナターゼ型の残存率と共に、表1にまとめた。
