Electronic anti‐injection effect for carbonyl in anchor group based on diphenylacetylene D 2 ‐π‐A sensitizer in dye‐sensitized solar cells

Abstract: Summary Up to now, in developing organic molecules for dye‐sensitized solar cells, the determining role of acceptors has not yet received enough attention. Herein, three novel sensitizers were prepared with D2‐π‐A structure, following cyanoacetic acid, acetic acid, and rhodanine‐3‐acetic acid as the acceptors, respectively. It was found that the thiocarbonyl and carbonyl groups, which are separated by two atoms with carboxyl group, effectively promoted molecular light harvesting, intramolecular charge transfer… Show more

“…However, here I focused my discussion on the highly sensitive structures, charge transfer and performance of the dye molecules [81]. Push-pull type dyes used in DSSC devices usually have donor-acceptor (D-A), donor-π-spaceracceptor (D-π-A) [82], D-π-π-A, D-A ′ -π-A or D-D ′ -π-A structure types [83,84,85]. The electron donating group with highly positive mesomeric effects, synthetic availability and modularity includes aromatic amines such as triphenyl amine [86], carbazole [87] and triazatruxene [88].…”
