Based on the studies of factors affecting the coupling, such ascatalyst,reaction time,the length of spacer etc.,this paper offers the optimal reaction conditionsand three typical experiment procedures. The mechanism for the formation and coupling reactionof PGR are also discussed.展开更多
A novel nanocomposite consisting of poly （3, 4-ethylenedioxythiophene）/poly （styre-nesulfonate） （PEDOT/PSS） and CuI was synthesized via the reduction of CuCl2 by NaI in an aqueous PEDOT/PSS solution.

The CuI in the composite was pure γ-phase, as was characterized by means of X-ray photoelectron spectroscopy （XPS）, X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The dye-sensitized solar cell with PEDOT/PSS-CuI （15% in wt） nanocomposlte as hole-transport electrolyte exhibited a considerable photocurrent, photovoltage and energy conversion efficiency （i.e. Jsc = 0.50 mA·cm^-2, Voc = 0.44 V, η= 0.1%）.展开更多
