“…The LD2 dye shows a more minor difference in ρ, whereby its experimentally determined value is slightly lower. This discrepancy could be due to the use of a 85:15 ratio of rutile:anatase polymorphs in the experimental TiO 2 layer; [ 39 ] unsaturated Ti atoms on a rutile (110) surface are spaced farther apart than on anatase (101), [ 54 ] so are less favourable as binding sites for bidentate carboxylate‐based dye anchors.…”

Endeavors in the field of dye‐sensitized solar cells (DSCs) have shown great promise when adopting a data‐driven approach to materials discovery, such as successful molecular‐scale predictions of light‐harvesting chromophores. However, predictions of DSC dyes would become much more sophisticated if a molecular‐to‐macroscopic DSC device prediction methodology existed. Thereby, a fully computational pipeline is presented that predicts device‐performance parameters of DSCs which contain varying dye combinations. Optimal pairing of complementary dyes is identified via a data‐driven workflow that affords cosensitized DSCs with maximum power‐conversion efficiencies. Six high‐performing DSC dyes are paired with partner dyes that are screened from a database of 8488 compounds using sequential heuristic filters. Existing models that predict short‐circuit‐current density (JSC) and open‐circuit voltage (VOC) parameters are adapted to predict singly sensitized and cosensitized DSC performance. The predictions for Jsc values of singly sensitized devices match experimental literature values with comparable accuracy to more computationally costly methods. Five out of six dye pairings are predicted to have greater JSC values when cosensitized compared to their corresponding singly sensitized devices, including two pairs that show strong Jsc boosts of +13% and +12% when cosensitized. Thus, the prospect of an entirely in‐silico prediction pipeline for DSC performance that can be used to realize the fully automated design of optimized cosensitized DSCs is demonstrated.

“…The synthesis of precursor monomer 4 is shown in Scheme . The monomer was made by the Horner–Wadsworth–Emmons reaction of 1 and 2 , followed by iodination to obtain the precursor monomer 4a . After GRIM reaction of this monomer, polymerization was attempted, but this did not result in polymer.…”

Two new polymer systems, poly(3-phenylenevinylene)thiophene (P3PVT) and poly(3-phenyl)thiophene (P3PT), were designed with the aim of obtaining a helical conjugated polymer via a living polymerization. The polymerization proceeded without transfer and termination reactions via the Kumada catalyst transfer condensative polymerization (KCTCP) mechanism, confirming the living nature of the polymerization. Solvatochroism and circular dichroism (CD) experiments showed the helical nature of P3PVT and the stacking behavior of P3PT in poor solvent conditions. Block copolymers of 3-alkyl-substituted polythiophenes and helical P3PVT were prepared to determine the aggregation behavior of such systems. Solvatochroism, CD, and AFM measurements showed that the blocks influence each other's behavior. If the P3AT block stacks before the helical P3PVT block organizes, one-handed helix formation is hindered. If helix formation occurs first, the stacking behavior is not influenced.

“…The effect of conjugated side groups on the thiophene π-bridge in an organic sensitizer was also studied [66]. It was reported that the introduction of electron donating conjugate thiophene olefinin side groups (dye 64) could red shift the λmax and increase JSC.…”
