Redox couple electrolyte in dye-sensitized solar cells
摘要
Abstract
This review surveyed the development and operating principles of dye-sensitized solar cells(DSSC),introduced the role of electrolyte redox couples in dye regeneration and electrochemical circuit closure,and analyzed their influence on the open-circuit voltage(VOC),short-circuit current density(JSC)and fill factor(FF).The energetic and kinetic design rules were elucidated,i.e.,regeneration and injection driving forces were rationalized by aligning the dyes' frontier molecular orbitals with the redox potential and the TiO2 conduction band,while current generation and FF were further governed by mediator diffusion and the catalytic activity of the counter electrode.The recent I-/I3-,Co(Ⅲ)/Co(Ⅱ),Cu(Ⅰ)/Cu(Ⅱ),TEMPO/TEMPO+,hydroquinone/benzoquinone(HQ/BQ)and Br3-/Br-systems were comparatively examined with respect to formal potential windows,visible-light self-absorption,diffusivity/viscosity and stability.The analysis showed that non-iodide mediators were,in general,more favorable for achieving higher VOC with reduced spectral competition.Cu-based and Co-based shuttles operated under low-overpotential and fast-regeneration conditions exhibited pronounced advantages for indoor energy harvesting.Relative to iodide,the key merits included electronically tunable potentials with balanced diffusion/selectivity,synergistic compatibility with high-activity counter electrodes that lowered interfacial impedance and robust efficiencies under AM 1.5G and 1000lx illumination.Finally,the prospects of DSSC indoor photovoltaics for sustainable Internet-of-Things(IoT)power supplies were outlined.关键词
