Abstract
AbstractThree 3,6‐di(4‐methoxyphenyl)amino N‐alkylated carbazoles were synthesized, characterized and incorporated in solid state dye‐sensitized solar cells. Devices using these compounds as solid hole conductors showed relative high Voc thanks to good energy level matching between them and D102 dye. However, they yield relatively low Jsc and FF compared to spiro‐OMeTAD‐based control devices, which is due to an order of magnitude lower mobility and conductivity with respect to spiro‐OMeTAD. Maximum PCEs for N‐ethyl and N‐hexyl 3,6‐di(4‐methoxyphenyl)amino carbazoles (2 a, 2 b) are 1.6 %, and 1.8 % respectively, whereas spiro‐OMeTAD devices gave 4.4 %. Stability tests in air under continuous illumination have been reported.
