Regeneration and recombination kinetics was investigated for dye-sensitized solar cells (DSCs) using a series of different cobalt polypyridine redox couples, with redox potentials ranging between 0.34 and 1.20 V vs. NHE. Marcus theory was applied to explai ...
Tools that assess the limitations of dye sensitized solar cells (DSSCs) made with new materials are critical for progress. Measuring the transient electrical signals (voltage or current) after optically perturbing a DSSC is an approach which can give infor ...
A review on a general description of photoelectrochem. cells with a specific focus on dye-sensitized solar cells, their device characterization and material components ...
We propose a passive factor, autocatalytic activity of some semiconductors (SnO2, WO3), for the loss of efficiency in dye-sensitized solar cells. On one hand, in the photoanode, SnO2 (or WO3) functions as a semiconductor to collect the photoelectrons that ...
An energy conversion efficiency of up to 5.24% has been attained, under AM 1.5 G illumination for a new dye-sensitized solar cell using TH305, as a low cost org. dye, ((CH3)4N)2S/((CH3)4N)2S2, as an org. electrolyte and CoS as counter electrode. ...
Unsymmetrical Zn phthalocyanine consisting of six S-aryl groups at alpha-positions and a carboxy anchoring group at beta-position has been designed and synthesized for dye-sensitized solar cells (DSCs) applications. The unsymmetrical phthalocyanine has bee ...
A new I-/(SeCN)(2) redox mediator has favorable properties for dye-sensitized solar cells (DSCs) such as less visible light absorption, higher ionic conductivity, and downward shift of redox potential than I-/I-3(-). It was then applied for DSCs towards in ...
Photoinduced mol. rearrangements are important in daily events essential for life such as visual perception and photo-protection of light harvesting complexes in plants. In this study we demonstrate that similar photorearrangements appear in an analogous t ...
A water-sol. org. redox couple (TT-/DTT) and new org. dyes (D45 and D51) have been developed for aq. dye-sensitized solar cells (DSCs). An optimal efficiency of 3.5% was obtained using the D51 dye and an optimized electrolyte compn. The highest IPCE value ...
