Predicting the dye-sensitized solar cell performance of novel linear carbon chain-based dyes: insights from DFT simulations

“…62 This focus on LCCs stems from their known attributes of high electrical conduction and very unusual optoelectronic behavior. 63–68 Our findings revealed that introduction of a 2-amino pyrrole unit as the donor moiety enhances molecular planarity compared to thiophene derivatives. This increased planarity, in turn, promoted efficient electron transfer between the donor and acceptor moieties, leading to improved performance in terms of LHE and, consequently, J sc .…”

Computational study of linear carbon chain based organic dyes for dye sensitized solar cells

“…[48][49][50][51][52][53] In this work we investigated by means of DFT approach a new class of metal free dyes for applications in DSSCs which is based on a linear carbon chain (LCC) linker between simple donor and acceptor groups. Since the high pconjugated system LCCs exhibit electrical conduction and very unusual optoelectronic properties, [54][55][56][57][58][59][60][61][62] moreover can be easily synthesized and their long-term stability is obtained. 63 We studied UV/VIS and electrochemical properties increasing the length of the bridge, moreover NLO properties were systematically investigated.…”

Pulsed laser ablation in liquid of sp-carbon chains: Status and recent advances

“…The possibility to produce different chains with tailored terminations and the realization of solid materials with long-term stability can open to the exploitation of the peculiar properties of sp-carbon chains in advanced applications. The peculiar nonlinear optical properties are appealing in optoelectronics while applications in biosensing and organic electronics have been recently reported [124][125][126].…”
