文摘

Phenothiazine derivatives with various conjugated linkers (furan, thiophene, and 3,4-ethylenedioxythiophene) were synthesized and used in dye-sensitized solar cells to study the effect of conjugated linkers on device performance. Among them, one with furan as a conjugated linker showed a solar energy-to-electricity conversion efficiency (畏) of 6.58%, an improvement of over 24% compared with the T2-1 reference cells鈥?5.29% under AM 1.5 G irradiation.
