Optimal Time-Invariant Operation Of A Power And Water Cogeneration Solar-Thermal Plant

摘要

A film of copper complex [CuL](NC>3)2 (L =2,3,8,9-tetraphenyl-l,4,7,10-tetraazacyclododeca-l,3,7,°-tetraene) formed on indium-tin oxide (ITO) coated glass by the solvent evaporation of the acetonitrile solution of the complex onto the ITO substrate, was characterized by ultraviolet-visible absorption spectroscopy, cyclic voltammetry, scanning electron microscopy, and photoelectrochemistry. The pho-toelectrochemical cell by using [CuL](NO3)2 modified ITO, a saturated calomel electrode, and platinum wire as working, reference and counter electrodes respectively in 1 M Na2SO4, was found to exhibit a large prompt and reproducible cathodic photocurrent density of 71 uA/cm2 under white light irradiation of 70 mW/cm2 at an applied potential of —0.4 V, and an incident photon to current efficiency (IPCE) of 1.1% at k — 660 nm. This Cu(II) complex photosensitizer has advantages of simple synthesis, low-cost, environmentally benign and good photoelectrochemical performance. ? 2011 Elsevier Ltd. All rights reserved.
