Embodiment
Flexible substrates sensitization solar battery has the advantages such as flexible, non-friable, lightweight, the fields such as such as mobile phone, wrist-watch, braid can be applied to, can widen the range of application of photovoltaic device greatly, and flexible substrates is with low cost, is conducive to industrialization and produces.
DSSC structure is mainly divided into three parts, that is: photoactive electrode, electrolyte, to electrode.Wherein photoactive electrode Main Function receives sunlight and is converted into electric energy, and solar cell circulation running is supported in electrolyte and the effect to electrode.The photoactive electrode of most of DSSC is all covered on electro-conductive glass by the titanium deoxid film adsorbing dyestuff to make.Titanium deoxid film is then be made up of the anatase titania nano particle of different size.Dyestuff is divided into the kind such as metal complex and organic molecule, and wherein metal complex uses comparatively extensive, and the complex particularly containing ruthenium shows high conversion efficiency especially.Dye molecule generally all contains carboxyl or phosphonate group, with the Interaction of substituents on titanium dioxide, thus dye molecule can be fixed on titanium dioxide granule surface.First the preparation of photoactive electrode is on electrically-conductive backing plate, utilize physics coating or hydro thermal method to prepare layer of titanium dioxide nano structure membrane, in order to reach higher conversion efficiency, the titanium dioxide of preparation should be anatase crystal, normally utilizes high temperature to make it be converted to required crystal formation.Subsequently the electro-conductive glass being coated with titanium deoxid film is immersed in dye solution, makes dye molecule at titanium dioxide nanostructure adsorption, reach the saturated rear taking-up of absorption and namely obtain photoactive electrode.In electrolyte, active ingredient is redox couple, and the most frequently used is iodine and iodide ion, also has and uses other organic molecules as ferrocene, disulfide derivative etc.The electro-conductive glass covered with the platinum layer with catalytic activity substantially to electrode.
DSSC operation principle is:
After DSSC receives illumination, dye molecule can absorb luminous energy, from ground state transition to excitation state, create the charge migration of central ion to part, and electronics is injected titania nanoparticles by part, electronics transmits further between titania nanoparticles, and is finally accumulated on the electrically-conductive backing plate of titanium dioxide layer rear.Because dye molecule is adsorbed on titania nanoparticles surface, and the nanostructure of titanium deoxid film determines it has very high specific area.Therefore use the titanium deoxid film with nanostructure effectively can improve the quantity of dye molecule in battery, and then improve its utilance to incident ray, improve conversion efficiency.
Dye molecule is activated into the excitation state of higher energy level by the ground state of lower level, and excitation state electronics is injected into TiO rapidly
2conduction band in, and by TiO
2collected by the conductive substrates of film, after then being done work by external circuit, arrive electrode; And the I in electrolyte
-dye molecule can be made to regenerate, the I3 of generation
-accept the electronics be delivered to electrode, thus complete current cycle.
Design of the present invention is mainly for some consideration following:
Based on the DSSC of flexible substrate.In the present invention, dyestuff Main Function absorbs sunlight, and dye molecule is excited to excitation state by energy and lower ground state, and then excitation state electronics is injected into TiO rapidly
2conduction band in, and to be collected by work electrode, by arriving electrode after external circuit acting; I in electrolyte
-reducible dyes molecule, thus complete current cycle.
Work electrode substrate adopts Ti sheet, and it has lightweight, flexible, that cost is low feature, can be applied to the surface of non-flat forms, and the work electrode film forming gross mass prepared thereon is better; Conductive plastics (ITO-PET) is adopted to electrode; Work electrode is coated with TiO
2with NiO mixture paste, can better absorbing dye (N719).
