Field of the Invention The present invention relates to a dye-sensitized solar cell module, which is more specific. a curved or protruding dye-sensitized solar cell module formed on a wire such that the length of the wire is increased by a plurality of bends or protrusions to increase the edge, thereby expanding the conduction path along the edges Current can flow better and consistently along the edges to reduce the series electrical resistance of the dye-sensitized solar cell module, thereby improving the photoelectric conversion efficiency of the solar cell module. [Previous Technical Standards; 1 Background of the Invention Since a dye-sensitized nanoparticle titanium oxide solar cell was developed in 1991 by Michael Gratzel of the Lausanne Institute of Technology (EPFL) in Switzerland, more than 15 studies related to this are underway. . Since the dye-sensitized solar cell has a significantly lower manufacturing cost than the existing tantalum solar cell, it can replace the existing amorphous germanium solar cell. Further, unlike the tantalum solar cell, the dye-sensitized solar cell is a photoelectrochemical solar cell mainly composed of a dye molecule capable of absorbing visible light to generate an electron hole pair and a transition metal 20 oxide which conducts the electrons. In general, a unit cell of a dye-sensitized solar cell absorbs a dye from an upper and lower transparent substrate, a conductive transparent electrode respectively formed on the transparent substrate, and a dye formed on a conductive transparent electrode corresponding to a first electrode. a transition metal oxide porous layer, a catalyst film electrode formed on the conductive transparent electrode corresponding to the second electrode 200950115, a genus oxide between the two, for example, a porous electrode and a catalyst film electrode 4 degrees gold Composition of electrolytes. 5 10 , and also the ancient 乍 , the existing 矽 solar power ~, has a very low efficiency. Therefore, increasing the efficiency of the battery itself is actively carried out, and research on integration into a mode (four) effect rate is also underway. A, therefore, there is a need for improvement of the module - a novel integration method - the integration method can solve the problem of efficiency reduction caused by integration of the dye-sensitized solar cell module in the dye-sensitized solar cell module In the group: Adjacent batteries or sub-modules are electrically connected by an overlap between a positive electrode and a negative electrode adjacent thereto. SUMMARY OF THE INVENTION In order to overcome such problems in the prior art, it is an object of the present invention to provide a dye-sensitized solar cell module that can provide a weight-to-weight (four) portion between cells or sub-modules At the point of - guide _ repair the most, to reduce the dye sensitized solar cell module _ series resistance, thereby improving the photoelectric conversion efficiency of the solar cell module. ^: Overcoming the purpose of the invention, the present invention provides a dye-sensitized solar cell module in which a towel adjacent battery or sub-module is electrically connected by a @f stack between a positive electrode and a negative electrode adjacent thereto, wherein the overlap portion At least one side of the portion has a wire drawn from one end of the positive or negative electrode with a curved or curved protrusion therebetween. 200950115 'The dye-sensitized solar cell module according to the present invention is bent or protruded, in particular, on a wire at the edge of the overlap between the battery or the sub-module at the edge of the sharp bend of the bend/projection point. And thus the length of the wire is increased by a plurality of bends or protrusions to increase the edge. Moreover, since the current '5 flows along the surface or the edge, especially the apex of a conductor, the conduction path is better by increasing the vertices and the current is uniformly distributed by the edges to reduce the series resistance of the dye-sensitized solar cell module. Uniformly flowing along the edge, thereby improving the photoelectric conversion efficiency of the solar cell module.且 Moreover, if the interference of an insulating film coating or the like is caused by the structure of a plurality of pointed tips, the insulating film can be easily broken and thus easily electrically connected.

[Embodiment 3 5 200950115 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail. The present invention relates to a dye-sensitized solar cell module in which an adjacent battery or sub-module is electrically connected by an overlap between a positive electrode and a negative electrode adjacent thereto, wherein at least the overlapping portion One side has a wire leading from one end of the positive or negative electrode and has a curved or curved protrusion in the middle. The invention will now be described with reference to the accompanying figures. Specific examples of the dye-sensitized solar cell module of the present invention are shown in Figs. 10 to 5, for example. In particular, since the current flows along the surface or edge, especially the top end of a conductor, in the present invention, a wire is not formed straight as in the prior art, but is intermediate (not the center but a non-end specific Part) has a curved or curved protrusion to increase the length of the wire to increase the longitudinal edge, or the edge can be increased by the protruding structure. The bend 15 can be formed into an arc shape as shown in Fig. 1, and preferably, as shown in Figs. 2 to 4, the bend of the wire has a horned edge, which provides a better The top of the surface facilitates the flow of current to the electrodes adjacent to the cell or sub-module. The projections may be of any shape, and as shown in Fig. 5, a four-corner or multi-angle projection having a plurality of apexes is preferred because it promotes current flow. Moreover, as shown in FIGS. 1 to 5, the wire is preferably a closed loop which is drawn from one end of the positive electrode or the negative electrode and is connected to the other end of the positive electrode or the negative electrode, because In this case, the current flowing to the adjacent battery or sub-module can be performed in two parts, so that the current flows evenly over the entire 200950115 wires. 5 ❹ 10 15 ❸ and, as shown in Figures 2 to 4, the bending of the wire preferably includes at least one sawtooth shape or protrusion and depression "[" shape (Figs. 3 to 4) because it can Maximize length and edge, top area. Moreover, the serrated or protruding and recessed "[" shape (meaning that the protrusion and depression "C" shape is formed on one plane from one side to the other or repeatedly) preferably has a regular spacing of ~ The uniform distribution promotes current flow to the electrodes adjacent to the cell or sub-module to allow current to flow evenly throughout the wire. The wire may be formed from a TC(trans (transparent conductive oxide) film or catalyst electrode film structure in a battery structure and then patterned, or it may be individually formed or coated by orifice printing or prior art printing methods. Forming a pattern after the repetition. In the latter case, the electrical connection between the TC0 film or the catalyst electrode film corresponding to the read battery electrode and the individually formed wires should be formed separately. A specific example of the present invention is shown in Fig. 1, wherein the electrical connection between the batteries is made up of a first electrode (lower electrode) of the first battery (left) and a second battery (right) adjacent thereto An overlap between the two electrodes (upper electrode), and a wire drawn from the lower electrode of the first cell (in the example shown, a layer of TC layer connected to a layer composed of an oxide and a dye) ) has an arcuate curvature. The lower electrode may be a TCO layer connected to a layer composed of an oxide and a dye as shown in FIG. 2; or, if the battery is formed symmetrically inverted as shown in FIG. 2, one and a catalyst electrode ( The pt) layer-connected TCO layer can be connected to a wire. And if a battery does not include a TCO layer, a catalyst electrode layer may be connected to the wire, or the layer may be patterned. One of the forms may be a wire. Another specific example is shown in FIG. 2, wherein an electrical connection between the plurality of integrated sub-modules is performed by the first electrode (upper electrode) of the first sub-module (left) and the first adjacent thereto An overlap between five of the second electrodes (lower electrodes) of the two sub-modules (right) forms 'and a wire drawn from the lower electrode of the second sub-module has a zigzag curve. The lower electrode may be a TCO layer connected to a catalyst electrode (Pt) as shown in FIG. 2; or, if a sub-module is formed in an inverted symmetric manner as shown in FIG. 1, A TCO layer consisting of a dye layer can be connected to a wire. Moreover, if a sub-module does not contain a tco layer, a catalyst electrode layer can be connected to a wire' or the layer itself can be a wire. In addition, as shown in Figs. 3 and 4, the wire may include a protrusion and a depression "c" shape repeated from one side to the other (Fig. 3), or a protrusion and depression "[" shape in the third figure. The straight line can be composed of the cj shape of the protruding and concave details that are repeated to the other side of the other side (Fig. 4, wherein the straight lines of Fig. 3 are still composed of protrusions and depressions). Therefore, the edge and the tip can be maximized. In the sub-modules shown in Figures 3 to 5, the electrical connection method between the batteries is different from each other depending on the connection between the batteries (parallel connection or series connection). The specific method of being electrically connected and electrically connected can be individually achieved according to the prior art solar cell integration method. Moreover, the connection between the battery or the sub-module and each of the batteries shown in FIGS. 1 to 4 The configuration is merely illustrative of the invention, and the scope of the invention is not limited thereto, and various known configurations of the dye-sensitized solar cell can be applied to the invention. 8 200950115 • Finally, as shown in Fig. 5, the wire Can contain a highlight. Above A protrusion can be obtained by forming a protrusion in addition to forming a bend. As shown in Fig. 5, a protrusion having a plurality of tips in a quadrangular or polygonal form promotes current flow. .5 A solar cell module can be used An overlapping portion of a conductive paste applied to the sub-modules formed as described above is fabricated to form an assembly, and an insulating film such as EVA is bonded to the upper/lower surface of the assembly, and the upper/joining is performed/ A protective glass on the lower surface.
