For the fist time the preparation of a mostly solid-state high efficiem electro-conductive material comprising 1-methyl-3-propylimidazolium iodide (MPII), benzimidazole (BI), iodine and lithium iodide was reported. In this electrolyte, BI acts as not only additives but also gelators. With its significant electrochemical properties, an overall efficiency of 3.07% was achieved under AM 1.5 (100 mW/cm^2). 相似文献

Amphiphilic polypyridyl mthenium(Ⅱ) complex cis-di(isothiocyanato)(4,4'-di-tert-butyl-2,2'-bipyridyl)(4,4'- dicarboxy-2,2'-bipyridyl)ruthenium(Ⅱ)(K005) has been synthesized and characterized by cyclic voltammetry, ^1H NMR, UV-Vis, and FT-IR spectroscopies. The sensitizer sensitizes TiO2 over a notably broad spectral range due to its intense metal-to-ligand charge-transfer (MLCT) bands at 537 and 418 nm. The photophysical and photochemical studies of K005 were contrasted with those of cis-Ru(dcbpy)2(NCS)2, known as the N3 dye, and the amphiphilic ruthenium(Ⅱ) dye Z907. A reversible couple at E1/2=0.725 V vs. saturated calomel electrode (SCE) with a separation of 0.08 V between the anodic and cathodic peaks, was observed due to the Ru^Ⅱ/Ⅲ couple by cyclic voltammetry. Furthermore, this amphiphilic ruthenium complex was successfully used as sensitizers for dye-sensitized solar cells with the efficiency of 3.72% at the 100 mW·cm^-2 irradiance of air mass 1.5 simulated sunlight without optimization of TiO2 films and the electrolyte. 相似文献

采用高压釜合成和乙酸乙酯/水萃取提纯的模式制备出高产率、高纯度的环状烷基硫碘盐. 高压釜合成在保证产率的前提下, 大大缩短了反应时间(反应时间仅为原来的1/3)|乙酸乙酯和水的萃取提纯模式在保证产品纯度的同时, 大大缩短了提纯时间, 还避免了有毒试剂的使用. 制备出的烷基环状硫碘盐作为碘源用于配制染料敏化太阳电池用电解质, 相应电池的光电转化效率接近使用传统烷基咪唑碘盐的电池. 电化学阻抗谱(EIS)测试表明环状烷基锍阳离子相比于烷基咪唑阳离子来说, 更有利于抑制电池内部的电子复合反应, 同时还能促进对电极上电子交换反应的进行, 最终可以提高电池的开路电压和填充因子. 相似文献

针对现有立体匹配算法对噪声敏感、易失真、在视差不连续区域与弱纹理区域误匹配率高的问题,提出一种改进Census变换与梯度融合的多尺度立体匹配算法。采用支持窗口内所有像素的加权平均灰度值作为Census变换的参考值,将Census代价与由水平和垂直方向归一化结合的梯度代价进行加权融合,通过设置噪声容限获得稳定的代价,提高了单像素匹配代价的可靠性;在多分辨率尺度下,采用改进引导滤波算法完成对匹配代价的聚合;通过视差提取获得视差图。实验结果表明,该算法在Middlebury测试平台上对标准立体图像对的平均误匹配率为4.74%,对27组扩展立体图像对的平均误匹配率为8.67%。该算法使得视差不连续区域与弱纹理区域的误匹配率进一步降低,且对噪声和光照等干扰表现出较好的稳健性。 相似文献

The DArk Matter Particle Explorer(DAMPE) is a satellite-borne detector for high-energy cosmic rays and y-rays. To fully understand the detector performance and obtain reliable physical results, extensive simulations of the detector are necessary. The simulations are particularly important for the data analysis of cosmic ray nuclei, which relies closely on the hadronic and nuclear interactions of particles in the detector material. Widely adopted simulation softwares include the GEANT4 and FLUKA,... 相似文献
