Description of the Invention: [Technical Field] [0001] The present invention relates to a portable solar charging device, and more particularly to a portable solar charging device comprising a concentrating solar battery module The device is designed to have the effect of long-term instant charging. [0002] [Previous technology] At present, the earth faces the problem of increasing energy shortage and the importance of saving energy. Generally, electrical appliances require high power to make Its operation, if it is necessary to use electrical appliances for outdoor use, in addition to carrying batteries, there is no other preferred pipeline, however, the storage capacity of the battery is limited, and it is necessary to find another power supply place for charging under long-term use. Solar cell systems can be one of the ways to solve this problem. However, the solar photovoltaic chips currently on the market generally have low photoelectric conversion efficiency. Therefore, if a higher power electrical appliance is required to generate electricity, a solar cell wafer of a large area is required. Therefore, it is less practical, so how to further improve the photoelectric conversion efficiency of solar wafers is a subject that the industry is currently studying. For example, a solar charging device includes a socket, a concentrating mask, a photoelectric conversion module, and a power connector; the concentrating cover is coupled to the socket, and the socket is coupled to the socket An accommodating space is formed between the reticle; the photoelectric conversion module is disposed in the accommodating space and is fixed on the pedestal. The photoelectric conversion module includes a plurality of solar chips and an electric storage device electrically connected to the solar ray The solar chip is a silicon wafer and is disposed corresponding to the concentrating cover; the power connector is connected to the socket and electrically connected to the battery. Before the solar charging device is used, 099142256 must be placed indoors or outdoors with sufficient light, and then the solar form number A0101 3/18 pages 0992073406-0 201225477 can receive the external light energy, and The light energy is converted into electrical energy, and then the electrical energy is stored into the electrical storage device to charge the portable electronic product with the solar charging device when the portable electronic product has insufficient power or no power. However, the conventional solar charging device still has the following drawbacks in practical use. If the user does not carry the solar charging device with him or the solar charging device is not placed in a place with sufficient light before use, Charging and using portable electronic products. Further, the solar wafer which is made of a tantalum wafer has a photoelectric conversion efficiency of about 15%, so that its photoelectric conversion efficiency is inferior. Referring to Taiwan Patent No. M350822, entitled "Portable Solar Energy Charging Device", the patent discloses a design of a solar wafer. It is mainly designed by solar GaAs/Ge (GaAs/Ge) single junction solar wafer or filled surface gallium/deslicated gallium/arc (InGaP/GaAs/Ge) multi-junction solar wafer to enhance the overall Photoelectric conversion efficiency. However, although its photoelectric conversion efficiency is high (ideal to more than 30%), its solar wafer cost is tens of times higher than the cost of silicon wafers. Considering factors such as environmentally friendly materials and expensive production equipment, the solar wafer is not optimal. The selection is referred to Taiwan Patent No. M3509 No. 5, entitled "Portable Solar Charger", which discloses a design of a solar panel module. The main purpose is to increase the output power of the solar panel by using a spherical lens on the casing as a light source. However, the patented solar panel and its structural design do not disclose the power required to use a low cost solar cell wafer or module to provide a stand-alone electrical appliance. In view of this, the creator of the present invention has carefully studied and proposed a portable solar charging device, in particular, a concentrating solar 099142256 form number A0101 page 4 / 18 pages 0992073406-0 201225477 battery module A portable solar charging device is constructed. The portable solar charging device can increase the short-circuit current of the output by providing a plurality of vertical multi-junction 矽-based solar cells with a concentrating module design, so as to provide a high-power power supply under a low component area, and When using v high-power electrical appliances outdoors, it has the effect of instant charging for a long time.
