Environmental problems such as global warming caused by continued use of fossil fuels are emerging. In addition, the use of uranium can cause problems such as radioactive contamination and nuclear waste disposal facilities. Therefore, the requirements for alternative energy sources have been proposed and corresponding research has been carried out, and representative ones are solar cells using solar energy.

A solar cell is a light absorbing material that generates electrons and holes when exposed to light. A component that directly generates electricity. This is due to the fact that in 1839 the French physicist Becquerel first discovered photo-generated electricity generated by a light-induced chemical reaction, followed by a similar phenomenon in solids such as selenium. Subsequently, in 1954, a cellar solar cell with an efficiency of about 6% was first developed at Bell Laboratories, and solar cell research continued around the inorganic germanium.

Such an inorganic solar cell element is composed of a p-n junction of an inorganic semiconductor such as germanium. The ruthenium which is a material of a solar cell is roughly classified into a crystalline ruthenium such as a single crystal ruthenium or a polycrystalline ruthenium. Among them, crystal enthalpy converts solar energy into electric energy more efficiently than amorphous bismuth, but its productivity is lowered due to the time and energy required to grow crystals.

Due to such a problem, studies have been made on solar cell elements that utilize photo-generated phenomena of organic substances instead of germanium. Photoelectric generation of organic matter is a phenomenon in which, when an organic substance is irradiated with light, photon absorption (Photon) generates an electron-hole pair, which is separated and respectively transmitted to the cathode and the anode. The flow of electric charge generates electricity. That is, generally, in an organic solar cell, when an organic substance composed of a bonding structure of an electron donor (Electron Donor) and an electron acceptor (Electron Acceptor) is irradiated with light, an electron-empty electron formation is formed in the electron donor. The pair of holes moves electrons to the electron acceptor to achieve electron-hole separation. This process is commonly referred to as "photo-induced charge carrier" or "photoinduced charge transfer (PICT)", and carriers generated by light are separated into electron-holes and passed through an external circuit. Generate electricity.

However, solar cells using ordinary organic substances have problems of low energy conversion efficiency and short service life, but in 1991, the Gratzel research group in Switzerland developed a photoelectrochemical solar cell using a dye as a sensitizer. Dye-sensitized solar cells. A photoelectrochemical solar cell proposed by Granzel et al. is a photoelectrochemical solar cell using an oxide semiconductor composed of a photosensitive dye molecule and titanium dioxide of a nanoparticle. Dye-sensitized solar power The cell is a solar cell in which an inorganic oxide layer such as titanium oxide having a dye adsorbed between a transparent electrode and a metal electrode is inserted into an electrolyte and produced by photoelectrochemical reaction. In general, a dye-sensitized solar cell is composed of two kinds of electrodes (photoelectrode and counter electrode), inorganic oxide, dye, and electrolyte, and since the dye-sensitized solar cell uses an environmentally-friendly substance/material, it is environmentally friendly. It has a high energy conversion efficiency of about 10% which is comparable to the amorphous bismuth solar cell in the conventional inorganic solar cell, and the manufacturing unit price is only about 20% of that of the solar cell, so the commercialization possibility is very high.

In general, the structure of the dye-sensitized solar cell includes a glass substrate, a first transparent electrode, an inorganic oxide layer to which a dye is adsorbed, an electrolyte layer, a second transparent electrode, an upper substrate, and the like, from the lower layer. The inorganic oxide layer is an n-type oxide semiconductor having a wide band gap such as TiO ₂ , ZnO, or SnO ₂ in the form of a nano porous film, and a dye having a monomolecular layer adsorbed on the surface thereof.

The principle of the dye-sensitized solar cell will be described below. When sunlight is incident on the solar cell, the HOME (Highest Occupied Molecular Orbital) energy absorption light energy of the dye (Dye) transitions to the LUMO (Lowest Unoccupied Molecular Orbital) energy level and is rapidly injected into the inorganic oxide layer (Conduction Band). , CB) forms conductive electrons. At this point, the HOMO energy level vacancies of the electron-depleting dye will be refilled by the electrons provided by the ions (I-) in the electrolyte layer.

That is, this can be explained by the fact that, as the sunlight is incident, conduction electrons are accumulated on the side of the inorganic oxide layer, and electrons are gradually lost on the side of the electrolyte layer, that is, holes are accumulated, and when there is an external load, the accumulated current is accumulated. The carrier forms an electromotive force.

Referring to the conventional method for producing a dye-sensitized solar cell, as shown in FIG. 1, the lower electrode substrate 10 is deposited on the glass substrate 11 by depositing FTO (Fluorine-doped Tin Oxide) or ITO first transparent electrode 12 thereon. The TiO ₂ colloidal solution is then sintered (Sintering) at a temperature above about 450 ° C to coat the TiO ₂ film 13 . By repeating this process, the thickness or state of the desired inorganic oxide layer can be adjusted. Next, it is immersed in the dye (Dye) solution for about 2 to 3 days, and the dye is colored on the surface of the TiO ₂ particles to form the dye layer 14. On the other hand, the upper electrode substrate 20 is coated with platinum (Pt) or the like on the glass substrate 21 by a general sputtering method, and the first transparent electrode 22 is deposited, and then the electrolyte 30 injection hole is formed. Thereafter, the lower electrode substrate 10 and the upper electrode substrate 20 are joined by the polymer encapsulating material 40, and the electrolyte 30 is injected as an anode material through a hole which is prepared in advance, and is completed by sealing.

Such a dye-sensitized solar cell can be produced at a production cost of a quarter of the conventional solar cell due to inexpensive raw materials and an easy-to-manufacture method, and is lightweight, thinned, transparent, and capable of realizing various hue. And can be applied to a variety of applications. Further, the dye-sensitized solar cell itself has flexibility, and in the case of realizing a suitable flexible transparent electrode, a flexible solar cell can be realized.

In particular, a dye-sensitized solar cell for a portable device as a power source for movement can be regarded as a necessary characteristic because the dye-sensitized solar cell itself has flexibility, so that a suitable flexible transparent electrode is realized. In the case of a flexible solar cell, a flexible solar cell can be realized.

However, in the current dye-sensitized solar cell manufacturing technology, a high-temperature sintering process is required, and it is difficult to use a transparent substrate such as a plastic or a transparent electrode such as a conductive polymer. Therefore, most of the current dye-sensitized solar cells use an oxide-based transparent electrode such as ITO (lndium Tin Oxide) which is a glass substrate.

Although an inorganic oxide layer capable of low-temperature sintering (about less than 150 ° C) has recently been developed, a commercially available conductive plastic substrate or the like can be used, but in this case, it is necessary to withstand a decrease in photoelectric conversion efficiency. Further, since the transparent upper electrode substrate has lower transmittance and conduction characteristics than the ITO substrate, an additional efficiency reduction can be expected. Therefore, it is quite difficult to achieve a highly efficient flexible dye-sensitized solar cell.

In addition, although such a conventional flexible dye-sensitized solar cell is infused with a liquid electrolyte or the like, as time passes, a liquid electrolyte due to injection is generated. Leakage of electrolyte leakage causes problems such as unstable service life.

Accordingly, the present invention has been made to solve the above problems, and an object thereof is to provide a metal flexible dye-sensitized solar cell and a method of manufacturing the same, which are coated or deposited on a substrate of a polymer material to adsorb a photosensitive dye molecule.
