Determination of HOMO and LUMO of [6,6]-Phenyl C61-butyric acid 3-Ethylthiophene Ester and poly (3-octyl-thiophene-2, 5-diyl) through voltametry characterization

Determination of HOMO and LUMO of [6,6]-Phenyl C61-butyric acid 3-Ethylthiophene Ester and poly (3-octyl-thiophene-2, 5-diyl) through voltametry characterization

HOMO and LUMO of organic compounds are basic parameters for the design and fabrication of an organic solar cell. This paper presents a technique to obtain HOMO and LUMO of an n-type polymer of [6,6]-phenyl C61-butyric acid 3-ethylthiophene ester (PCBE) and a p-type polymer of poly (3-octyl-thiophene...
