Journal ArticleDOI

Metallated conjugated polymers as a new avenue towards high-efficiency polymer solar cells

TL;DR: A soluble, intensely coloured platinum metallopolyyne with a low bandgap is synthesized, which showed a power-conversion efficiency with an average of 4.1%, which clearly demonstrates the potential of metallated conjugated polymers for efficient photovoltaic devices.
Journal ArticleDOI

Tuning the absorption, charge transport properties, and solar cell efficiency with the number of thienyl rings in platinum-containing poly(aryleneethynylene)s.

TL;DR: The synthesis, characterization, and photophysics of a series of solution-processable and strongly visible-light absorbing platinum(II) polyynes containing bithiazole-oligo(thienyl) rings were presented and provides an attractive approach to developing conjugated metallopolymers offering broad solar absorptions and tunable solar cell efficiency.
Journal ArticleDOI

Effect of Oligothienyl Chain Length on Tuning the Solar Cell Performance in Fluorene-Based Polyplatinynes

TL;DR: In this article, a series of solution-processable and strongly visible-light absorbing polyplatinynes containing oligothienyl-fluorene ring hybrids were synthesized and characterized.
Journal ArticleDOI

Long K-Doped Titania and Titanate Nanowires on Ti Foil and FTO/Quartz Substrates for Solar-Cell Applications

TL;DR: In this article, the influence of fabrication conditions on nanowire structure and morphology is investigated, and it is shown that the presence of potassium is essential for nanowires formation.
Journal ArticleDOI

Very-low-bandgap metallopolyynes of platinum with a cyclopentadithiophenone ring for organic solar cells absorbing down to the near-infrared spectral region

TL;DR: Two solution-processable metallopolyynes of platinum functionalized with the electron-deficient 4H-cyclopenta[2,1-b:3,4-b']dithiophen-4-one spacer and their model molecular complexes were synthesized and developed for the applications of polymer solar cells, and represent the lowest optical bandgap yet reported for platinum(II) metalopolyynes to date.
