Abstract
The utility model relates to a large-current concentrating photovoltaic photoelectric conversion receiver, and belongs to the technical field of solar power generation. The receiver comprises a circuit substrate, a corrosion groove, a metal welding strip line, a circuit negative electrode, a negative electrode linkage area, a circuit positive electrode, a positive electrode linkage area, a concentrating photovoltaic cell negative electrode, a concentrating photovoltaic cell chip, and a small round blind hole array. The circuit substrate is welded with the concentrating photovoltaic cell chip and the small round blind hole array. The circuit substrate is divided into the circuit positive electrode and the circuit negative electrode by the corrosion groove. The circuit positive electrode and the circuit negative electrode are respectively provided with the corresponding positive electrode linkage area and the negative electrode linkage area. The metal welding strip line directly connects the concentrating photovoltaic cell negative electrode with the circuit negative electrode. The metal welding strip line can access large current generated by the concentrating photovoltaic cell chip to the circuit substrate. The metal welding strip line is welded on an end face of the concentrating photovoltaic cell chip. Thus, the number of welded strip lines on the negative electrode of the concentrating photovoltaic cell chip is reduced, thereby greatly improving yield rate of the products.
Description
Technical field
The utility model relates to a kind of photovoltaic generation parts, is specifically related to a kind of large electric current condensation photovoltaic photoelectric conversion receiver, belongs to solar energy generation technology field.
Background technology
Condensation photovoltaic photoelectric conversion receiver is the core component in light gathering photovoltaic power generating system, is electric energy for the transform light energy directly lens being converged.The multiple of lens is larger, and the quantity of the condensation photovoltaic battery chip using in unit are is just fewer, and the cost of corresponding light gathering photovoltaic power generating system will be fewer, so the multiple of present lens also does larger and larger, even exceedes thousand times.Along with the continuous increase of lens multiple, the electric current producing on corresponding condensation photovoltaic photoelectric conversion receiver is also just increasing, and existing condensation photovoltaic photoelectric conversion receiver can not meet the electric current demand of the luminous energy generation electric energy after more than 500 times lens converge; In addition at processing condensation photovoltaic photoelectric conversion receiver product, particularly on the negative electrode of condensation photovoltaic battery chip in the process of weld metal band line, the number of weld metal band line is more, the probability that condensation photovoltaic battery chip is damaged is just larger, will strengthen like this condensation photovoltaic photoelectric conversion receiver processing fraction defective.
Summary of the invention
The purpose of this utility model is to provide a kind of large electric current condensation photovoltaic photoelectric conversion receiver, and this assembly is to overcome the deficiencies in the prior art.
In order to realize above-mentioned technical purpose, the technical scheme that the utility model is taked is a kind of large electric current condensation photovoltaic photoelectric conversion receiver, it is characterized in that, it comprises circuit substrate, etching tank, metal welding tape splicing line, circuit negative electrode, negative electrode bonding pad, circuit positive electrode, positive electrode bonding pad, condensation photovoltaic battery negative electrode, condensation photovoltaic battery chip and roundlet blind hole array, on circuit substrate, be welded with condensation photovoltaic battery chip and roundlet blind hole array, the circuit substrate groove that is corroded is divided into circuit positive electrode and circuit negative electrode, on circuit positive electrode and circuit negative electrode, be respectively equipped with corresponding positive electrode bonding pad and negative electrode bonding pad, metal welding tape splicing line is directly communicated with condensation photovoltaic battery negative electrode and circuit negative electrode.
Described circuit substrate is the one in alumina ceramic-base copper-clad plate, alumina ceramic plate, al nitride ceramic board, LED ceramic substrate, alundum (Al2O3) ceramic substrate, high heat-conducting ceramic substrate and ceramic base copper-clad plate.
Described metal welding tape splicing line is the one in pure aluminum wire, aluminium alloy wire and gold thread.
Described negative electrode bonding pad and positive electrode bonding pad are can welding zone.
Advantage of the present utility model and good effect are: 1. the large electric current that metal welding tape splicing line can produce condensation photovoltaic battery chip is linked on circuit substrate; 2. weld metal welding band line on the negative electrode of condensation photovoltaic battery chip one end face, so just reduces the quantity with line of welding on the negative electrode of condensation photovoltaic battery chip, has greatly improved the yield of this product.
Accompanying drawing explanation
Fig. 1 is a kind of large electric current condensation photovoltaic photoelectric conversion receiver schematic diagram.
Wherein: 1, circuit substrate, 2, etching tank, 3, metal welding tape splicing line, 4, circuit negative electrode, 5, negative electrode bonding pad, 6, circuit positive electrode, 7, positive electrode bonding pad, 8, condensation photovoltaic battery negative electrode, 9, condensation photovoltaic battery chip, 10, roundlet blind hole array.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of large electric current condensation photovoltaic photoelectric conversion receiver, as shown in Figure 1, on circuit substrate 1, be welded with condensation photovoltaic battery chip 9 and roundlet blind hole array 10, circuit substrate 1 groove 2 that is corroded is divided into circuit positive electrode 6 and circuit negative electrode 4, on circuit positive electrode 6 and circuit negative electrode 4, be respectively equipped with corresponding positive electrode bonding pad 7 and negative electrode bonding pad 5, metal welding tape splicing line 3 is directly communicated with condensation photovoltaic battery negative electrode 8 and circuit negative electrode 4.Each of metal welding tape splicing line 3 can be born the electric current of 20 amperes, many strip metal welding just can be born larger electric current with line 3, when line 3 is with in processing metal welding, due to the minimizing of welding quantity, just can greatly improve the production yield of this product simultaneously.
In order to prevent that high temperature from producing deformation or coming off each layer on circuit substrate 1, designed many roundlet blind hole arrays 10 around circuit substrate 1.
In the utility model patent, as becoming row embodiment, the quantity of metal welding tape splicing line is more than four, directly welding lead of positive electrode bonding pad and negative electrode bonding pad, or in this region, weld wiring draw-in groove etc., roundlet blind hole array can be also square blind hole array.Therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
