Description

A kind of DSSC that can two-sided light inlet and preparation method thereof
Technical field
The present invention relates to a kind of DSSC that can two-sided light inlet and preparation method thereof, belong to photovoltaic material and field of optoelectronic devices.
Technical background
DSSC (Dye Sensitized Solar Cell, i.e. DSSC) is since 1991 come out, and is low owing to its cost of manufacture, manufacture craft is simple and easy to repetition becomes hot research in recent years.Through years of development, its photoelectric conversion efficiency has reached 11%, though its efficient and stability have much room for improvement,, this battery still is considered to one of photovoltaic device that has commercial application prospect.DSSC mainly constitutes by conductive substrates, nanoporous sull, dye sensitizing agent, electrolyte with to electrode.Traditional is metal Pt or the sheet glass that is coated with thicker Pt to electrode, light tight.If desired from electrode is advanced light, then require Pt thin (as Liu, Z. and M. Misra (2010). Nanotechnology 21 (12): 125703; Ito, S., S. M. Zakeeruddin, et al. (2008). Nat Photon 2 (11): 693-698.), could guarantee that like this part light can see through Pt arrival and be positioned on the sensitizer of light anode.But, cross thin Pt to electrode, can influence whole catalytic performance again, so just cause present stage most of batteries only to select also to have limited solar cell and must adopt transparent conducting glass as the light anode substrate from the light anode one side light inlet that transparent conducting glass is arranged.Now on the market preferably transparent conducting glass be ITO(indium tin oxide Indium tin oxides) or FTO(contain the tin ash Fluor-doped tin oxide of F) glass.Owing to the monopolization of foreign patent, add In, the Sn price of continuous rising, make the price of electro-conductive glass also constantly rise.In addition, the energy of classic flat-plate solar cell conversion is relevant with the angle of incidence of sunlight degree, preferably build partly cloudy weather conditions zone in, under the not abundant condition of sunlight, as the cloudy day or when cloudy, cloud layer makes the energy of traditional cell integrated collection of panel solar reduce greatly to the scattering of sunray.
Summary of the invention
Problem to be solved by this invention is the deficiency that exists at above-mentioned existing solar cell, and a kind of DSSC that can two-sided light inlet and preparation method thereof is provided.
Technical scheme of the present invention:
A kind of DSSC that can two-sided light inlet comprises the light anode and to electrode, electrolyte is filled between light anode and the hole to electrode; Described smooth anode is made of transparent conducting glass, titanium dioxide dense layer and titanium dioxide porous film, and porous membrane has adsorbed the sensitizing dyestuff molecule; Described electrode is made up of latticed conductive layer and the Catalytic Layer that is attached on the latticed conductive layer.

The transparent conducting glass of described smooth anode comprises FTO or ITO electro-conductive glass.
The TiO of described smooth anode 2Porous membrane, thickness are 8-20 μ m.
The preparation method of above-mentioned DSSC that can two-sided light inlet comprises the steps:
1. the preparation of light anode: adopt standard semiconductor technology to clean glass substrate, drying, the porous semiconductor layer of formation sensitization on substrate of glass;
2. to the preparation of electrode
Directly adopt wire netting as network-like conductive layer, directly deposit Catalytic Layer thereon; Or in nonconducting network-like substrate the depositing electrically conductive film, deposit Catalytic Layer more thereon; Or the method with photoetching forms latticed photoresist pattern in transparent substrate, deposits layer of conductive film then on latticed photoresist pattern, deposits Catalytic Layer more thereon, at last photoresist is removed;
3. the light anode that sensitization is good and electrode is superimposed is middlely filled with electrolyte.
Further technical scheme is:
In the preparation process to electrode, also comprising can not be by the preparation of the passivation layer of electrolyte corrosion, and method is high temperature sintering, sputtering method, czochralski method etc.
Deposit passivation layer is different different because of the material of conductive layer on latticed conductive layer, if directly adopt wire netting, and can be by the way of high temperature sintering directly at wire netting surface formation metal oxide layer; Other metal oxides such as ITO, ZnO, TiO 2Deng adopting sputtering method, czochralski method etc.; When electrolyte that DSSC adopted to the conductive layer non-corrosiveness or when having adopted corrosion resistant conductive layer, this step can be omitted.
The invention has the beneficial effects as follows: 1) light both can be from the incident of light anode, also can be to electrode incident, also can be from the light anode with to electrode incident simultaneously, make device (as cloudy day or cloudy) under the not abundant situation of light that high conversion rate still be arranged, improved the utilization ratio of sunlight greatly; 2) adopt wire netting, flexible materials such as plastics can change with the alteration of form of light anode, can realize crooked; 3) introducing of metal film has better conductivity than transparent conductive material, can significantly reduce the series resistance of battery; 4) latticed surface contacts with mesh-structured can effectively the improvement with electrolytical, is easy to form the nanocatalyst particle of high catalytic activity, helps improving the open circuit voltage of battery, fill factor, curve factor and battery efficiency; 5) base material is selected extensive, with low cost, environmental friendliness, is realized industrialization; 6) conductive layer, the preparation method of passivation layer and Catalytic Layer is simple, and is efficient, and the depositing temperature scope is selected wide, is easy to realize scale of mass production; 7) can be used for the light anode DSSC of most forms, can significantly improve open circuit voltage, fill factor, curve factor and the conversion efficiency of DSSC, have broad application prospects.
