SUBSTITUTED TRIS(BIPYRIDINE)COBALT(II) COMPLEXES IN DSSCS: FACTORS WHICH AFFECT AND LIMIT THEIR PERFORMANCE AS MEDIATORS IN DYE,Used
Delivery time: 8-12 business days (International)
Appropriately substituted tris(bipyridine)cobalt(II) complexes (Cobpy) have been found to function adequately as electron transfer mediators in dyesensitized solar cells (DSSCs). However, the performance of Cobpy in DSSCs has so far not equaled that of more traditional mediators based on the iodide/triiodide redox couple. This book primarily focuses on research conducted to investigate the reason for the poorer performance of Cobpy mediators, although significant attention is also given to efforts to develop a solidstate Cobpy DSSC. A series of twoelectrode experiments was devised and an apparatus built to perform threeelectrode experiments, a task made more complex by the thin layer, "sandwich cell" geometry of the DSSC. The results of this work suggested that mass transfer of the Cobpy is often ratelimiting and significantly slower than that of iodidebased mediators. A mostly theoretical treatment of mass transfer predicted that diffusion within the mesoporous titania layer, rather than an intrinsically slow bulk diffusion rate, is hampering DSSC performance. This work should be of interest to researchers investigating DSSCs or diffusion within nanostructures.
