| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 97 === The soluble polypyrrole (PPYDEHS) has been synthesized using ammonium peroxodisulfate as the oxidant and di-(2-ethylhexyl) sodium sulfosuccinate (DEHS) as the anion. The PPYDEHS was blended with [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) with 1:1 (wt%) ratio, and dimethyl formamide or 1,2-dichlorobenzene was used as a solvent to spin-coat these materials on indium tin oxide (ITO) glass to become an photoactive layer of the polymer solar cell. The fabricated polymer solar cell with above organic layer, poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT-PSS) and ITO anode, and aluminum cathode show less than 1% overall efficiency.
The counter electrodes used in dye-sensitized solar cell (DSSC) have been prepared by admicellar polymerization of pyrrole on fluorine doped tin oxide glasses (FTO) using ammonium peroxodisulfate or ferric chloride as oxidant and anionic (sodium dodecyl sulfate, DEHS), or cationic (cetyltrimethyl ammonium bromide), or nonionic (Triton® X-100, Tween®-20) surfactant. The fabricated DSSC’s with polypyrrole-coated counter electrodes show 5-10% better in overall photoelectric conversion efficiency than those DSSC’s assembled with plantinum as the counter electrode.
