Abstract:
We reported enhanced characteristics of the organic solar cells (OSCs) using pyromellitic dianhydride (PMDA) material as cathode interfacial layer. This PMDA cathode interfacial layer was used in a bilayered structure consisting of lithium fluoride (LiF) and pyromellitic dianhydride (PMDA) at the interface of poly(3-hexylthiophene-2,5-diyl)(P3HT)+[6,6]-phenyl C61 butyric acid methyl ester (PCBM) and Al. Better performance enhancement compared to OSCs without a cathode interfacial layer or with a single LiF interfacial layer was achieved by using a bilayered interfacial structure. The OSC with a cathode interfacial structure with LiF and PMDA combination showed 2.08 % power conversion efficiency (PCE) value, while the OSC with a single LiF cathode interfacial layer showed 1.72 % PCE value and the OSC without any cathode interfacial layer showed 1.35 % PCE value, respectively. And Cole-Cole plots of OSCs showed that bilayered interfacial structure reduced impedance probably by improving the electron transport between Al and PCBM+P3HT.
