[2] 太阳能电池是一种由于光伏特效应而将太阳能直接转化为电能器件。 当太阳光 照到太阳能电池上吋， 就会把太阳的光能变成电能， 产生电流。 当多个太阳能 电池串联或并联起来就可以成为有较大输出功率的太阳能电池矩阵了。 太阳能 电池是一种大有前途的新型能源， 具有持久性、 清洁性和灵活性三大优点。 太 阳能电池寿命长， 只要太阳光存在， 太阳能电池就可以一次投资而较长期使用 ； 与火力发电、 核能发电相比， 太阳能本身是一种环保绿色能源不会引起环境 污染； 太阳能电池可以大中小并举， 大到百万千瓦的中型电站， 小到只供一户 用的太阳能电池组， 这是其它电源无法比拟的。 [2] Solar cells are a device that directly converts solar energy into electrical energy due to the special effects of photovoltaics. When the sun shines on the solar cell, it turns the sun's light energy into electricity and generates electricity. When a plurality of solar cells are connected in series or in parallel, it can be a matrix of solar cells with a large output power. Solar cells are a promising new energy source with three advantages of durability, cleanliness and flexibility. Solar cells have a long life. As long as sunlight is present, solar cells can be used for a longer period of time. Compared with thermal power generation and nuclear power generation, solar energy itself is an environmentally friendly green energy source that does not cause environmental pollution. Solar cells can be both large and medium. Large-scale power plants of up to one million kilowatts, as small as one solar battery for one household, which is unmatched by other power sources.
[3] 随着太阳能的进一步广泛应用， 在太阳能领域中高的光强可以提高太阳电池的 填充因数和有效降低成本， 但光线太强温升会使芯片之外的 PCB板熔化或断裂， 所以科学合理地处理 '芯片之外剩余的聚光'至关重要， 此点是整个电池应用的关 键问题之一， 直接决定了太阳能聚光系统的寿命； 另一个关键问题是同一太阳 电池芯片上接收的光强不均匀会降低其填充因数， 从而影响电池效率和寿命， 最终也导致成本的提高。 因此聚集光系统中处理'太阳能芯片之外剩余的聚光 '和' 均匀度'在整个太阳能聚光电池的应用中是十分重要的， 目前在市场上还没有提 出能够解决上述问题的方案。  [3] With the further widespread application of solar energy, high light intensity in the solar field can increase the filling factor of solar cells and effectively reduce the cost, but too strong temperature rise will cause the PCB board outside the chip to melt or break, so science Proper handling of 'the remaining spotlight outside the chip' is critical, and this is one of the key issues in the entire battery application, directly determining the life of the solar concentrating system; another key issue is the same on the same solar cell chip. Uneven light intensity reduces its fill factor, which affects battery efficiency and longevity, and ultimately leads to increased costs. Therefore, it is very important to process the 'concentration of the light outside the solar chip' and the 'uniformity' in the concentrated light system in the application of the entire solar concentrating battery, and there is currently no solution on the market that can solve the above problems.
[4] 本发明的主要目的是提供一种太阳能电池芯片保护结构， 其可以防止芯片之外 的 PCB板因温升过高而熔化或断裂， 有效延长太阳能电池的寿命。 [4] A main object of the present invention is to provide a solar cell chip protection structure which can prevent a PCB board outside the chip from being melted or broken due to excessive temperature rise, thereby effectively extending the life of the solar cell.
[5] 本发明的次要目的是提供一种太阳能电池芯片保护结构， 其可有效提高太阳能 电池上光线'均匀度'， 克服聚光型太阳能电池的缺失点， 充分发挥其优势， 大大 提高太阳能电池的有效利用率。 [6] 为实现上述目的， 本发明的解决方案是： 一种太阳能电池芯片保护结构， 在电 池芯片上部设有一块聚光镜， 其中： 该聚光镜对应电池芯片大小的位置设有透 光区， 而在聚光镜的透光区外缘为反光区。 [5] A secondary object of the present invention is to provide a solar cell chip protection structure, which can effectively improve the 'uniformity of light' on a solar cell, overcome the missing point of the concentrating solar cell, fully exert its advantages, and greatly improve solar energy. Effective utilization of the battery. [6] In order to achieve the above object, the solution of the present invention is: a solar cell chip protection structure, a concentrating mirror is disposed on the upper part of the battery chip, wherein: the condensing mirror is provided with a light transmitting area corresponding to the position of the battery chip, and The outer edge of the light transmitting area of the concentrating mirror is a reflective area.
[7] 所述的聚光镜为平板玻璃。  [7] The concentrating mirror is a flat glass.

[13] 所述透光区为曲面透镜。  [13] The light transmitting area is a curved lens.
[14] 釆用上述方案后， 本发明将电池芯片上的聚光镜划分为透光区与反光区， 而透 光区的大小正好对应芯片的大小， 则芯片可以有效收集太阳光； 另太阳能芯片 之外的不需要利用的聚光被反光区反射或吸收掉以免照射至 PCB板， 造成温升使 PCB板融化或破裂， 以此有效延长太阳能电池的使用寿命。  [14] After the above scheme is adopted, the present invention divides the concentrating mirror on the battery chip into a light transmitting region and a reflective region, and the size of the light transmitting region corresponds to the size of the chip, so that the chip can effectively collect sunlight; The concentrated light that is not needed is reflected or absorbed by the reflective area to avoid illuminating the PCB, causing the temperature rise to melt or rupture the PCB, thereby effectively extending the service life of the solar cell.
[15] 而对透光区进行毛面处理或设为光学曲面透镜， 可使射入芯片的光线通过毛面 的漫反射或曲面透镜的折反射从新分布， 使之入射至芯片的光线均匀化分布， 提高太阳电池芯片的填充因数， 克服聚光型太阳能电池的缺失点， 充分发挥其 优势， 大大提高太阳能电池的有效利用率。  [15] The matte treatment of the light-transmissive area or the use of an optical curved lens allows the light incident on the chip to be newly distributed through the diffuse reflection of the matte surface or the buckling of the curved lens, so that the light incident on the chip is uniformized.

[23] 配合图 1至图 7所示， 本发明的太阳能电池芯片保护结构， 是在太阳能电池芯片 2上部设有一块聚光镜 1， 其中： 该聚光镜 1对应电池芯片 2大小的位置设有透光 区 11， 而在聚光镜 1的透光区 11外缘为反光区 12。 [23] As shown in FIG. 1 to FIG. 7, the solar cell chip protection structure of the present invention is in a solar cell chip. 2 is provided with a concentrating mirror 1 in the upper part, wherein: the condensing mirror 1 is provided with a light transmitting area 11 corresponding to the position of the battery chip 2, and the reflecting edge 12 is located at the outer edge of the light transmitting area 11 of the condensing mirror 1.
[24] 透光区 11的大小正好对应电池芯片 2的大小， 则电池芯片 2可以有效收集太阳光 ； 另太阳能芯片 2之外的不需要利用的聚光被反光区 12反射或吸收掉以免照射至 PCB板， 造成温升使 PCB板融化或破裂， 以此有效延长太阳能电池的使用寿命。  [24] The size of the light-transmitting area 11 corresponds to the size of the battery chip 2, so that the battery chip 2 can effectively collect sunlight; and the concentrated light outside the solar chip 2 that is not needed is reflected or absorbed by the reflective area 12 to avoid illumination. To the PCB board, the temperature rise causes the PCB board to melt or rupture, thereby effectively extending the service life of the solar cell.
[25] 如图 1、 2所示为本发明的实施例 1， 该聚光镜 1为平板玻璃， 中部对应电池芯片 2大小的区域为透光区 11， 而在透光区 11周缘的反光区 12釆用表面镀有反光膜形 成或是在反光区 12上设置反光器件实现。  As shown in FIG. 1 and FIG. 2, the condensing mirror 1 is a flat glass, and the area corresponding to the size of the battery chip 2 in the middle is the light transmitting area 11, and the reflective area 12 on the periphery of the light transmitting area 11 is shown in FIG.

Here, the light-transmissive area 11 is configured to uniformly distribute the light incident on the battery chip 1. As shown in FIG. 5, the principle of uniformizing the light surface of the matte surface is as follows: Conventional concentrated light is caused by the optical lens to be deflected (ie, Surface normals have a specific distribution and orientation)
， 光线的传播方向也趋于一个特定的小区域和方向， 这样就造成特定方向上的 区域的光线强度比较高， 其它的就比较低， 形成很明显的强度梯度， 即我们通 常说的不均匀； 在这种情况， 我们引入毛面， 因毛面的表面有凸凹不平的近似' RThe direction of light propagation also tends to a specific small area and direction, which results in a higher intensity of light in a particular direction, and others are lower, forming a distinct intensity gradient, which is what we usually call uneven. In this case, we introduce a matte surface, because the surface of the matte surface has an uneven approximation 'R
'面 （常规 20#号粒度就可以实现， 不同粒度对应的效率也不一样， 在此不详述'Face (normal 20# size can be achieved, the efficiency of different granularity is not the same, not detailed here
， 即有不同趋向的曲面法线， 这样若有特定分布和朝向的光线打到此面上， 就 会发生一系列的折反射， 形成我们所谓漫反射即原来有特定分布和朝向的光线 在毛玻璃的作用下重新分布， 使出射的光线在各个方向的分布就比较均匀， 概率机会相等） ， 提高太阳电池芯片 2的填充因数， 克服聚光型太阳能电池的缺 失点， 充分发挥其优势， 大大提高太阳能电池的有效利用率。 , that is, the surface normals with different orientations, so that if a specific distribution and the direction of the light hits this surface, a series of deflections will occur, forming what we call diffuse reflections, which originally had a specific distribution and orientation of the light in the frosted glass. Redistribution under the action of the device, the distribution of the emitted light in all directions is relatively uniform, the probability of opportunity is equal), the filling factor of the solar cell chip 2 is improved, the missing point of the concentrating solar cell is overcome, the advantages are fully utilized, and the advantage is greatly improved.
