摘要：

Three 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 V-oc thanks to good energy level matching between them and D102 dye. However, they yield relatively low J(sc) 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 (2a, 2b) are 1.6 %, and 1.8% respectively, whereas spiro-OMeTAD devices gave 4.4 %. Stability tests in air under continuous illumination have been reported.
