Inventive description: [Technical field of invention] The invention relates to a package structure of a solar cell, a package structure of a special battery module, and a focus of a wafer holder slidable on a heat dissipation base Placed in the center of the solar cell [Prior Art] Due to the growing shortage of oil, solar energy is one of the alternative energy sources, and its application is becoming more common. In order to improve the efficiency of the solar cell, the improvement of the structure and the improvement of the assembly technology are all continually 太阳 = the sun is concentrating on the sun, so that for the future development trend, the current can be reduced by the amount of lightning. F knows that the solar cell is directly wired on the heat sink, and then the concentrating lens is fixed to the button. The organization group (4) is difficult to perform optical concentrating _, and the module design system is small and cannot be arbitrarily assembled into the required size. U.S. Patent No. 4,210,121 to Stark provides a kind of work on t, and the solar cell is placed in a linear focus (linear foc collector), with water cooling increasing efficiency, assembly is quite difficult, for ",, It is also not allowed to be assembled into the required size and has been eliminated. U.S. Patent No. 4,834,8,5, to Erbert, provides a back conductor with a prefabricated solar cell. Place the lens. = 造, such as a solar cell module package [invention] 200919741 The purpose of this is to provide a package structure of a focusing solar cell module, using a length of the pillar to fix the focus lens to the sun Above the focal length of the battery, the sun cake is placed on the solar cell, and the slidable wafer holder is placed on the splice after the crystal welding and the wire is finished, and the charm is placed in the center of the solar cell, and the optical assembly is light and simple. And the optical concentrating assembly can be separately performed. The second object of the present invention is to provide a packaging structure of a focusing solar cell module, which is formed by a loosely-formed material (4). The upper surface of the invention is provided with a good heat dissipation design. A further object of the present invention is to provide a package structure for a focusing solar cell module, a coupling device around the heat dissipation base, and a solar cell capable of combining the money sealing cake to form the sun. The battery board, the module capable of finely pouring the material, is assembled into the edge of the party. In order to achieve the above object and other purposes, the first aspect of the present invention teaches a package structure of a solar cell, a fixed length (four) Set the 隹, 透: from the solar cell - above the health distance, so that the sun is mixed with the solar cell, and the spleen ΐΓ move the wafer holder, in the center of the crystal and the wire is placed on the cooling pad to slide the central 'including: A heat sink base for good heat dissipation 平坦 flat 'back surface is a heat sink, the same area as the focus lens, support poly,,,, lens and solar cells on it, surrounded by a combination of devices, can be a good name ^ Yang battery module formation The solar panel, the hot base is square, the length of the struts is predetermined, so that the focusing lens 11 is set to the solar cell, a sun illuminates the entire solar cell, and the pillar is square at the base. :? for 3 to 6 'and the pillar can be closed = wall replacement, - ray mirror, focus the sun on the solar cell ί is a Fresnel lens, convex lens or refractive index: slip; =詈In the center, the wafer holder can be placed at the center of the solar cell at the end of the heat-dissipating pad, and is fixed in a variety of thicknesses. It is located near the focus with the height of the battery, so that the sun shines on the entire solar power instead of - Point;-a wafer holder' has a wafer and a wiring port for the solar cell 200919741, a die bond on it and a wire (wire b negative terminal pad to connect the current; a solar cell, crystal welding: ^ Connect the positive and negative wiring wires of the solar cell to the wafer by wire bonding. 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施Perspective view of a focused battery module. The focusing type solar cell module 1 has a heat-dissipating base η made of a material, and the front surface is a good surface of the flat class = the surface of the surface is a 16'-shaped fin or a sheet-shaped heat sink, and the surface is preferably The heat sink base 11 has a square or regular hexagon shape: the area of the upper surface of the susceptor 11 is the same as the area of the focus lens 13, and the focal lens 13 has a bonding device around the top thereof. (not shown), for example, the buckle and the left side are the female buckles, which can be combined with the required size of a plurality of packaged solar cells. The plurality of pillars 12, such as the divergence seat u, are square J-support columns U^, the right heat-dissipating base 11 is a regular hexagon, and the pillars 12 are three or ς can also be replaced by a side wall. The length of the struts 12 is silent, so that the poly 隹 g 13 is fixed to the solar cell - (four), above the distance - so that the sunlight illuminates the entire lens = = lens 13, and the sun is recorded on the solar cell. Focusing lens 13 ii ί, ear lens (Fresnei iens), convex Wei or folded group progressive lens. The thermal base 11 has a heat dissipation pad 14 fixed to the center of the heat dissipation base u, so that the wafer holder 15 can slide on the heat dissipation 14 and the focus lens 13 is fixed in the center of the anode battery, and has various thicknesses. To adjust the solar power == near the focus, so that the sun shines on the entire solar cell instead of a point. The wafer holder 15 has a wafer pad and a wiring pad for die bonding of the solar cell wafer and a wire bond, and a positive and negative terminal pad on the outside to externally connect the current. Figure 2 is a perspective view of a wafer holder perspective 200919741 in accordance with an embodiment of the present invention. Fig. 2(A) is a plan view of the wafer holder. The wafer holder 15 is made of a material 20 having good heat dissipation, and has an insulating layer 2 on the center of which has a wafer pad 23 (see FIG. 2(B)) and a wiring pad 25 for crystal welding of the solar cell wafer 24 (die) Bond) is a wire bond (not shown) to the terminal pad 25, and has a positive terminal pad 26 and a drain pad 27 on the outside to externally connect the port.
