TL;DR: In this article, two D-π-A dyes, one with a strong electron withdrawing cyanoacrylic acid DPP 20 and another with a weak acceptor carboxylic acid (CPO) DPP 21, have been synthesized and characterized for their application in dye-sensitized solar cells, and the role of electron withdrawing strength of the acceptor anchoring groups on the optoelectronic properties of chromophoric π spacer molecules was analyzed.

TL;DR: In this paper, a novel class of Ru(II) sensitizers (TFRS-51 and TFRS-54) with a 4,4′-dicarboxy-2,2′-bipyridine anchoring ligand and two trans-oriented isoquinolinyl (or quinolinyl) pyrazolate ancillaries were designed, characterized and used to fabricate dye sensitized solar cell (DSC) devices.

TL;DR: In this paper, the lowest energy metal-to-ligand charge transfer transitions in these complexes could be tuned from 500 to 590 nm by choice of appropriate ligands and the highest occupied molecular orbital varied over 400 mV.

TL;DR: In this article, an easily scalable method for the deposition of nanocrystalline hematite photoelectrodes based on spin-coating of a mixed solution containing tin(II) and iron(III) chlorides followed by thermal treatment is presented.

TL;DR: Results indicate that the use of mechanochemically synthesized perovskites provides a promising strategy for the formation of crystalline films demonstrating slow charge recombination and low trap density.
