Sterically Controlled Interfacial Charge-Transfer Mechanisms in Unsymmetrical Squaraine Dyes for Suppressed Aggregation and Enhanced Performance in High-Efficiency Dye-Sensitized Solar Cells. [PDF]

ChemistryOpen
Molecular engineering of cis‐configured unsymmetrical squaraine dyes reveals how branched alkyl substituents regulate aggregation and interfacial charge–transfer processes on TiO2. Steric shielding suppresses H‐type aggregation and retards interfacial recombination, leading to enhanced recombination resistance and improved open‐circuit voltage.
