  Mechanisms of Instability in Ru-Based Dye Sensitization Solar Cells

  摘要：

  In-situ infrared studies performed with operating Ru-complex-sensitized wet solar cells using a total reflection technique reveal that the ruthenium complex (both tri- and mononuclear) attached to TiO2 is photoelectro-chemically transformed and irreversibly consumed under conditions of insufficient regeneration by iodide or from the oxide within the nanocrystalline TiO2 pores. The sensitizer [(Ru(bpy)(2)(CN)(2))(2)Ru(bpca)(2)](2-) (bpy is 2,2'-bipyridine, bpca is 2,2'-bipyridine-4,4'-dicarboxylate) decomposes into fragments; one of them was identified to be Ru(bpy)(2)(CN)(2). For the sensitizer Ru(bpca)(2)(SCN)(2), it is shown that a molecular fragment (absorbing at 2013 cm(-1)) is generated which is diffusing out of the nanostructured TiO2 layer. Due to its correlation with the photocurrent density, it is identified as a product of the oxidized sensitizer. Due to a high serial resistance introduced by the total reflection element and the resulting low fillfactor of the sensitization cell during in-situ measurements, only small photocurrents (5-10 mu A cm(-2)) could be passed through the sensitizing interface. Since the rate of product formation should be proportional to the ratio of photocurrent density to iodide concentration, the iodide concentration was correspondingly reduced (1-10 mM) as compared to the conditions in a solar cell (10 mA cm(-2), 1 M). This spectroscopic technique was developed because efforts to produce stable sensitization solar cells proved to be unsuccessful due to sealing problems. Our experiments do not seem to permit extrapolation to 10(7)-10(8) electron transfer numbers for sensitizing Ru complexes, and real long-term testing is required for reevaluating long-term performance.

  摘要：

  通过微波辅助合成获得的MOF-253（Al（OH）（dcbpy），dcbpy = 2,2'-联吡啶-5,5'-二羧酸）用于构建含dcbpy的负载Ru络合物（MOF -253-Ru（dcbpy）2）与Ru（dcbpy）2Cl2中的Ru（II）协调其开放的N，N'-螯合位点。所制得的MOF-253-Ru（dcbpy）2可作为双功能光催化剂，用于同时还原CO2以生成甲酸和CO，以及对1,2,3,4-四氢异喹啉（THIQ）进行半脱氢以获得3， 4-二氢异喹啉（DHIQ）。表面支持的MOF-253-Ru（dcbpy）2的性​​能优于通过混合匹配策略获得的Ru掺杂的MOF-253（Ru-MOF-253），表明在MOF中使用开放式配位位点直接构建表面支持的复合物是获得MOF支持的均质复合物的一种较好策略。这项研究表明使用MOF作为构建多功能异相光催化系统平台的可能性。光催化CO2还原与有机物的高度选择性

  New cis-Ru(3,3'-dcbpy)(2)(NCS)(2) photosensitizer (where 3,3'-dcbpy is 3,3'-dicarboxy-2,2'-bipyridine) was synthesized using Ru(DMSO)(4)Cl-2 as a starting material and characterized. Its photophysical and redox properties were compared with those of cis-Ru(4,4'-dcbpy)(2)(NCS)(2) and cis-Ru(5,5'-dcbpy)(2)(NCS)(2). The photoelectrochemical properties of the three dyes adsorbed on the surface of the nanocrystalline TiO2 electrodes as well as on self-assembly monolayers (SAMs) were investigated. The photocurrents generated by sensitized TiO2 electrodes were much higher than those by SAMs. And cis-Ru(4,4'-dcbpy)(2) showed a most efficient photosensitizer in both systems. The mechanism is discussed in the paper. (C) 2000 Published by Elsevier Science S.A. All rights reserved.
