  2. 1. Gold-Based Nanoparticles and Thin Films : Applications to Green Nanotechnology

    Author : Pia Lansåker; Claes-Göran Granqvist; Gunnar Niklasson; Ulf Helmersson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green nanotechnology; transparent conductors; nanoparticles; gold coalescence; substrate effect; temperature effect; Fysik; Physics;

    Abstract : The use of gold-based nanoparticles and thin films is very promising when it comes to improving several green nanotechnologies. Therefore, in order to further their use in applications such as electrochromic devices, photovoltaics, light-emitting diodes and photocatalysis, the aim of this work was to study the growth of gold-based nanoparticles and thin films.

  4. 2. 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.
