Properties of the thin films were characterized by X-ray diffraction(XRD), four-point probe, Hall-effect measurement, UV-Vis spectrophotometer, and scanning electron microscopy(SEM). The effects of sputtering pressure, oxygen partial pressure and deposition temperature on properties of microstructure and optoelectronics properties of PET/ITO thin films were investigated in detail. High-quality ITO thin films on PET substrates with the resistivity as low as 8.5×10-4 Ω·cm and the optical transmittance over 80% in the visible spectrum range were obtained.展开更多

P3HT （poly-3-hexylthiophene）. It was used as an electron donor, PCBM （[6, 6]-phenyl C6 l-butyric acid methyl ester） as an electron acceptor and PEDOT： PSS used as a HIL （hole injection layer）. These materials were deposited by spin coating method on the flexible substrates. Photolithography method is used to etch ITO. The electrical parameters of the fabricated cells were investigated by means of J （V）, FF （fill factor）, the efficiency （r/）, photocurrent and IPCE measurement. It was observed that 45% of the absorbed photons are converted into current. The results obtained using etching technology by photolithography is better than that obtained in the clean room.展开更多

The contents of the PANI films,surface elements, electrochromic property and electrical conductivity were characterized by energy dispersive X-ray spectrometer （EDS）, cyclic voltammetry （CV） and electrochemical impedance spectroscopy （EIS）. The experimental results show that differences exist among cycle stability, redox reversibility and response time of polyaniline films on these two kinds of substrates, but the electrochromic phenomenon of the PANI films is in substantial agreement. The equilibrium transmittance spectra in the visible region （400-800 nm） for the PANI film on flexible PET/ITO substrate was obtained at different applied potential from -0.4 to 1.5 V. The results show that the transmittance of the PANI film by applying voltage is adjustable in a row and has excellent electrochromic performance.展开更多
