Description
Technical field
The present invention relates to the dye sensitized nano crystal solar cell, refer in particular to a kind of complex light anode and preparation method thereof; Complex light anode of the present invention is on graphene film, to cover TiO
2Inculating crystal layer is template growth TiO
2Nano-wire array and on nano-wire array the growing nano particle form composite construction, can be applicable in the DSSC.
Background technology
The shortage of non-renewable energies such as oil, coal, natural gas makes energy crisis day by day become one of restraining factors of social development, economic development and scientific technological advance, and the material that taps a new source of energy is key subjects that the our times various countries must at first solve with utilizing new forms of energy; And solar energy have cleaning, safe in utilization, inexhaustible, utilize cost low and do not receive plurality of advantages such as geographical conditions restriction, be the desirable energy that solves the energy and environmental problem; Dye sensitized nano crystal solar cell (DSSC) is based on a kind of novel solar cell that Nano-technology Development is got up; Has cost of manufacture low (its cost be merely silicon solar cell 1/5 ~ 1/10); Production technology is simple, pollution-free; Insensitive to variations in temperature and intensity variation, good light stability is a kind of extremely promising environment protection solar cell.
The porous nano crystallized semiconductor thin film that DSSC is mainly covered by transparent conduction base sheet, dyestuff, electrolyte solution and electrode formed.After receiving optical excitation; Dye molecule is from the ground state transition to excitation state, and the dyestuff that is in excitation state is injected into electronics in the conduction band of semiconductor nano, and the electronics that is injected in the conduction band transmits in semiconductor film; After arriving semiconductor film and electro-conductive glass contact-making surface, get into external circuit; The oxidation-reduction potential of oxidation-reduction pair poor in semi-conductive quasi-Fermi level and the electrolyte solution when open circuit photovoltage of DSSC is illumination; Short-circuit photocurrent depends on light capture rate, electron injection efficiency and the electric transmission efficient of light-sensitive coloring agent, and the resistance of reduction charge recombination effect and conduction band substrate of glass can improve fill factor, curve factor.
At present; How to make DSSC obtain higher photoelectric conversion efficiency; Improve stability test; Increase the service life is the hot issue of research always, and the compound of the capture rate of dyestuff adsorbance, light and the conduction of accelerated electron and inhibition electronics is three key factors that improve the electricity conversion of DSSC; Development along with nanometer technology; In DSSC, Graphene and monodimension nanometer material (like nano wire, nanotube etc.) have good electron-transporting to novel nano material with its good performance applications; Electronics is separated with the hole, suppress the generation of dark current.
Because Graphene has fabulous conductivity, there is report to utilize Graphene and TiO recently
2Nanocrystalline produced with combination light anode is used for the making of DSSC; Report in the ACS NANO magazine in 2010 like people such as Yang, at TiO
2In mix 0.6 % Graphene make the light anode, the short-circuit current density of DSSC is by 11.25 mA/cm
2Bring up to 16.29 mA/cm

UV-reduction of graphene oxide and its application as an interfacial layer to reduce the back-transport reactions in dye-sensitized solar cells. Chemical Physics Letters, 2009; 483,124-127.).
One-dimensional nano structure has superior electronics to separate and conductibility, and its length is on micron order, it is thus clear that scattering of light and absorbent properties greatly strengthen; Human hydrothermal methods such as Aydil obtain TiO
2It is lower that nano-wire array obtains efficient, the nano-wire array process TiCl that 4 μ m are long
4Obtain the transformation efficiency of 3 % after the aqueous solution is handled, Aydil is low owing to TiO efficient
2The specific area of array is little, causes not enough (the B. Liu and E. S. Aydil. Growth of Oriented Single-Crystalline Rutile TiO of dyestuff that adsorbs
2Nanorods on Transparent Conducting Substrates for Dye-Sensitized Solar Cells [J]. J. Am. Chem. Soc., 2009,131 (11), 3985-3990.); In order to remedy the little deficiency of nano-wire array surface area, tree-shaped/ZnO nanoparticle structure that people such as Wu have constructed the ZnO nanometer also is applied in the DSSC, and the compound of 3.5 μ m length has obtained the transformation efficiency of 3.74 %, is superior to TiO
2The battery of nano particle assembling because the existence of nano particle makes the adsorbance of dyestuff increase, thereby has increased electricity conversion.(C.?T.?Wu,?W.?P.?Liao,?J.?J.?Wu.?Three-dimensional?ZnO?nanodendrite/nanoparticle?composite?solar?cells[J].?Journal?of?Materials?Chemistry,?2011,?21,?2871-2876.)
