Honeycomb Carbon: A Review of Graphene

Two-steps synthesis of a poly(acrylate–aniline) conducting hydrogel with an interpenetrated networks structure

Preparation and photocatalytic degradability of TiO2/polyacrylamide composite

TiO(2):Eu(3+) nanorods are hydrothermally grown and used to fabricate a bilayer film electrode in a dye-sensitized solar cell. A light-to-electrical energy conversion efficiency of 8.0% and a quantum efficiency of 93.7% (at 575 nm) is achieved in this solar cell. The high efficiency is due to the improvement of ultraviolet light harvesting via a down-conversion luminescence process by the Eu(3+) ion and the increase of light scattering by one-dimensional TiO(2).

Enhancing the photoelectrical performance of dye-sensitized solar cells using TiO2:Eu3+ nanorods

Application of poly(acrylic acid-g-gelatin)/polypyrrole gel electrolyte in flexible quasi-solid-state dye-sensitized solar cell

A kind of closed-microporous hybrid with poly(acrylic acid)-poly(ethylene glycol)-polypyrrole (PAA-PEG-PPy) was synthesized template-free by in situ polymerization and micro-phase separation of PPy in PAA-PEG gel. This novel structure hybrid was used as a matrix in preparing polymer gel electrolytes for quasi-solid-state dye-sensitized solar cells (QS-DSSC). It shows high liquid electrolyte absorbency and salt tolerance, which are benefits for improving photovoltaic performance of QS-DSSC.
