Electronic structures of two types of TiO2 electrodes: inverse opal and nanoparticulate cases
Taro Toyoda,Witoon Yindeesuk,Tsuyoshi Okuno,Masaya Akimoto,Keita Kamiyama,Shuzi Hayase,Qing Shen +6 more
TL;DR: In this article, a comparison between the electronic structures of inverse opal (IO) and nanoparticulate (NP)-TiO2 electrodes was made, and the electronic structure details were obtained from optical absorption, fluorescence, and valence band studies in order to clarify the nature of the higher photovoltaic performance observed in sensitized solar cells using IO-TiO 2 electrodes.
