摘要：

Organic photovoltaic (OPV) solar cells have the advantage of simple processing, low cost, semi-transparency, high-mechanical flexibility, and light weight. Investigations into OPV solar cells using bulk heterojunction (BHJ) structures have driven extensive and successful efforts to enhance their power conversion efficiencies (PCE). It has been demonstrated that nanoscale morphology is essential for improved transport of charge carriers in the OPV cell containing poly (3-hexylthiophene) (P3HT) and (6,6)-phenyl C6(1) butyric acid methyl ester (PCBM) structures, and for enhancing its efficiency. Inorganic semiconductors such as zinc oxide (ZnO) have been incorporated into the BHJ structures due to their high carrier mobilities; it is inexpensive and ZnO-nanorod arrays offer an excellent controllable transport path. In this contribution the effect of solvent to control the degree of mixing of the polymer, fullerene and ZnO nanoparticles components into a hybrid inorganic-organic structure, is investigated. Evolution of the domain size, structure and optical properties of hybrid ZnO:P3HT:PCBM thin films spin-coated from different weight is studied, using High Resolution Transmission Electron Microscopy (HRTEM), UV-visible spectroscopy, X-ray diffraction (XRD) and spectroscopic ellipsometry (SE).
