Performance of P3HT:PCBM Organic Solar Cell with ZnO Buffer Layer

Article Preview

Abstract:

In this paper, we explore the characteristics of bulk heterojunction solar cell based on poly (3-hexyl thiophene) [P3HT] and [6,6]-phenyl-C61-butyric acid methyl ester [PCBM] by introducing a buffer layer with device configuration of ITO/ZnO/P3HT:PCBM/Au. Nanostructured ZnO with individual diameter around 20-50 nm was used as the buffer layer and its effects on the short circuit current density, Jsc and open circuit voltage, Voc were investigated. It was found that, the electrical characteristic of the organic solar cell was obviously changed by introducing the buffer layer. Solar cell characteristic with Voc of 0.3939 V was obtained but the Jsc was very small. The surface topology of the P3HT:PCBM was investigated using an atomic force microscopy (AFM). ZnO nanoparticles were observed using a field emission scanning electron microscope (FESEM) and the electrical properties of the solar cell was measured using a solar simulator with a current – voltage (I-V) measurement system.
