Dye-sensitized solar cells (DSCs) constitute a novel class of hybrid organic-inorganic solar cells. At the heart of the device is a mesoporous film of titanium dioxide (TiO2) nanoparticles, which are coated with a monolayer of dye sensitive to the visible ...
Today a plethora of soluble cyanine dyes absorbing from the ultra-violet to the near infrared domain are available owing to more than a century of research and development, mostly in photographic industry. Numerous properties of cyanine dyes suggest that t ...
This thesis investigates amorphous (a-Si:H) and microcrystalline (μc-Si:H) solar cells deposited by very high frequency plasma enhanced chemical vapor deposition (VHF-PECVD) in the n-i-p or substrate configuration. It focuses on processes that allow the us ...
CuIn1-xGaxSe2 (CIGS) solar cells show a good spectral response in a wide range of the solar spectrum and the bandgap of CIGS can be adjusted from 1.0 eV to 1.7 eV by increasing the gallium-to-indium ratio of the absorber. While the bandgaps of Ga-rich CIGS ...
A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, includes the steps of prepg. a suspension of semiconducting nanoparticles in a volatile suspension agent, depositing the particle suspension on a conducting subst ...
Four Zn(II)-tetra(carboxyphenyl)porphyrins in soln. and bound to metal oxide (TiO2, ZnO, and ZrO2) nanoparticle films were studied to det. the effect of the spacer length and anchoring group position (para or meta) on their binding geometry and photoelectr ...
Silver nanoparticles have been prepared using a "terminated gas condensation" technique. An unprecedented control of 5-6 nm-size nanoparticles with well defined shape and variable surface densities has been achieved. The technology is shown to permit indep ...
Increasing awareness that popular functionals fail to describe many energies accurately has ended expectations of black-box DFT usage. The performance of nine d. functionals, compared by computing the bond sepn. energies of 72 illustrative hydrocarbons wit ...
This study presents a comparative approach to investigate the potentials of two innovative methods for the synthesis of ZnO and Al-doped ZnO. The first method is a precipitation system working in mild hydrothermal conditions (90°C) using a tubular reactor ...
High-efficiency p-i-n microcrystalline silicon single-junction solar cells are fabricated and their longterm stability is investigated. We focus in particular on the stability of the absorber layer after atmospheric storage in absence of light and compare ...
