Flexible organic photovoltaic devices based on oligothiophene derivatives
摘要:
For the purpose of developing flexible organic photovoltaic devices, we have fabricated two flexible devices using 5-formyl-2, 2':5', 2":5", 2"'-quaterthiophene (4T-CHO), 5-formyl-2, 2':5', 2":5", 2'":5"', 2"''-quinquethiophene (5T-CHO) and 3, 4, 9, 10-peryle-netertracarboxylic dianhydride (PTCDA).The PET-ITO/4T-CHO/PTCDA/AI device has an open circuit voltage (V∝) of 1.56 V, photoelectric conversion efficiency of 0.77%.The PET-ITO/ST-CHO/PTCDA/AI device has a V∝ of 1.70 V, photoelectric conversion efficiency of 0.84%.The two flexible devices have high V∝(1.56 and 1.70 V).It is possible that intermolecular hydrogen bonding between-CHO group of nT-CHO and carboxylic dianhydride of PTCDA contributes to enhancing the efficiency by promoting interfacial electron transfer and eliminating the subconducting band trap sites.
