  2. 1. Exploring Dye-Sensitized Mesoporous NiO Photocathodes : from Mechanism to Applications

    Author : Lei Tian; Haining Tian; Leif Hammarström; Fabrice Odobel; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NiO; p-type; dye-sensitized solar cells; solid state; charge separation; charge recombination; charge diffusion; transport time; surface states; electron conductor; dye regeneration; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : Increasing attention has been paid on solar energy conversion since the abundant solar energy possesses the potential to solve the problems on energy crisis and climate change. Dye-sensitized mesoporous NiO film was developed as one of the attractive photocathodes to fabricate p-type dye-sensitized solar cells (p-DSCs) and dye-sensitized photoelectrosynthetic cells (p-DSPECs) for electricity and chemical fuels generation, respectively.
