000130808 5203_ $$aThree compounds based on aniline, thiophene and vinylpyrimidine as anchoring group have been prepared and studied as light harvesting units for dye-sensitized solar cells (DSSCs). They comprise thiophenyl p-spacer systems with one or two thiophenes (AT-Pyri, ATT-Pyri) and aniline as donor which is functionalized, in one case, with an hydroxyl group (HO-AT-Pyri). The bithiophene based dye (ATT-Pyri) shows higher extinction coefficients and smaller transition energy, as well as broader absorption spectrum. Thus, despite lower dye uptake, devices based on one thiophene and with the hydroxyl group (HO-AT-Pyri) have slightly higher power conversion efficiencies (¿) as compared with the analogous dye without this group (AT-Pyri). However, the best performing device is based on the dye with bithiophene bridge (ATT-Pyri) when a co-adsorbent is added to avoid the aggregation of the dye. The photovoltaic parameters of cells based on these vinylpyrimidine dyes are enhanced over 1000 h, especially for ATT-Pyri devices, which reach a ¿ = 6, 4%. © 2022 The Authors
