技术领域technical field
本发明涉及光伏发电领域，特别涉及一种新型太阳能光伏组件。The invention relates to the field of photovoltaic power generation, in particular to a novel solar photovoltaic module.
背景技术Background technique
太阳能光伏发电系统(简称光伏)是一种利用光生伏特效应而将太阳光能直接转化为电能的系统，其光电转换的主要部件是晶体硅光伏电池，当太阳光照到晶体硅光伏电池上时，晶体硅光伏电池就会把太阳的光能变成电能，产生电流。目前，光伏组件主要包括玻璃层、前层胶膜、间隔阵列布置的若干电池片、后层胶膜和光伏背板，所述玻璃层、前层胶膜、若干电池片、后层胶膜和光伏背板依次胶合，为了提高光伏组件的发电效率，需要减少组件表面太阳光的反射，从而增加组件的辐照度，提高太阳能电池的光电转换效率。现有技术中，一般采用下述方法：1、减反镀膜玻璃：利用在玻璃表层镀层减反膜，从而使太阳光减少对光伏组件的反射，增加光伏组件对光照的吸收，从而增加组件功率和发电量；2、超薄玻璃：降低组件正面玻璃的厚度，从而增加阳光通透率，降低光照折射率，增强辐照强度；上述方法需要改变光伏组件的结构，对常规结构的光伏组件并不适用；而改变光伏组件的结构会增加生产成本，且由于太阳光是由不同的波长的光组成，不同波长具有不同的光子能量，只有光子能量大于单结电池材料的带隙，才能被吸收继而发电，如果光子能量小于单进结电池材料的带隙是会透过材料的，对了多结串联的电池片因每节电池片不是无限厚度，因此不可能吸收所有的光子能量大于单结电池带隙的太阳光，依然会有一部分太阳光透过电池到背板上，影响光伏组件的发电效率的同时，如若将太阳能组件一般安装于建筑物顶部，还不能起到很好的隔热的效果。Solar photovoltaic power generation system (referred to as photovoltaic) is a system that uses the photovoltaic effect to directly convert sunlight energy into electrical energy. The main component of its photoelectric conversion is a crystalline silicon photovoltaic cell. When the sun shines on the crystalline silicon photovoltaic cell, Crystalline silicon photovoltaic cells will convert the sun's light energy into electrical energy and generate electric current. At present, a photovoltaic module mainly includes a glass layer, a front layer of adhesive film, a number of cells arranged in a spaced array, a rear layer of adhesive film, and a photovoltaic backplane. Photovoltaic backsheets are glued together in turn. In order to improve the power generation efficiency of photovoltaic modules, it is necessary to reduce the reflection of sunlight on the surface of the modules, thereby increasing the irradiance of the modules and improving the photoelectric conversion efficiency of solar cells. In the prior art, the following methods are generally adopted: 1. Anti-reflection coated glass: use an anti-reflection coating on the surface of the glass to reduce the reflection of sunlight on the photovoltaic module and increase the absorption of light by the photovoltaic module, thereby increasing the power of the module and power generation; 2. Ultra-thin glass: reduce the thickness of the front glass of the module, thereby increasing the sunlight transmittance, reducing the refractive index of light, and enhancing the radiation intensity; the above method needs to change the structure of the photovoltaic module. Not applicable; changing the structure of photovoltaic modules will increase production costs, and since sunlight is composed of light of different wavelengths, different wavelengths have different photon energies, and only photon energies greater than the band gap of single-junction cell materials can be absorbed Then generate electricity, if the photon energy is less than the band gap of the single-junction cell material, it will pass through the material. For multi-junction series cells, because each cell is not infinitely thick, it is impossible to absorb all photon energy greater than single-junction. Part of the sunlight in the band gap of the battery will still pass through the battery to the backplane, which will affect the power generation efficiency of the photovoltaic module. At the same time, if the solar module is generally installed on the top of the building, it cannot provide good heat insulation. Effect.
因此，为了进一步提高光伏组件的发电效率,中国专利号为201220404358.7的实用新型公开了一种新型太阳能光伏组件，包括玻璃层、前层胶膜、间隔阵列布置的若干电池片、后层胶膜和光伏背板，所述玻璃层、前层胶膜、若干电池片、后层胶膜和光伏背板依次胶合，所述光伏背板包括被电池片覆盖的镜面反射部和位于电池片间隙的漫反射部。该太阳能光伏组件可提高光子利用率和输出功率。其镜面反射部51为在被电池片3覆盖的光伏背板5上镀锌，而成为镜面反射部51。该关伏组件的的光伏背板包括被电池片覆盖的镜面反射部和位于电池片间隙的漫反射部，因此，光线从玻璃层射入，入射到电池片上的光被利用，同时部分穿透电池片的光线被光伏背板反射而再次利用，从而提高光伏组件的发电效率，但是仅仅在背板5上镀形成的镜面反射部其反射效果不好，且其设于背板与后层胶膜之间，后层胶膜容易上溢到镜面反射部的正面，形成了部分遮挡，影响镜面反射部51的反射效果，降低发电效率。Therefore, in order to further improve the power generation efficiency of photovoltaic modules, the utility model of Chinese Patent No. 201220404358.7 discloses a new type of solar photovoltaic module, which includes a glass layer, a front layer of adhesive film, a number of cells arranged in a spaced array, a rear layer of adhesive film and Photovoltaic backplane, the glass layer, the front layer of adhesive film, several battery sheets, the rear layer of adhesive film and the photovoltaic backplane are glued together in sequence, and the photovoltaic backplane includes a specular reflection part covered by the battery sheet and a diffuser located between the battery sheets. reflective part. The solar photovoltaic module can improve photon utilization rate and output power. The mirror reflection part 51 is galvanized on the photovoltaic backplane 5 covered by the battery sheet 3 , and becomes the mirror reflection part 51 . The photovoltaic backplane of the off-voltage module includes a specular reflection part covered by the cells and a diffuse reflection part located in the gap between the cells. Therefore, the light enters from the glass layer, and the light incident on the cells is utilized and partially penetrates. The light from the battery sheet is reflected by the photovoltaic backplane and reused, thereby improving the power generation efficiency of the photovoltaic module, but the reflection effect of the specular reflection part formed only on the backplane 5 is not good, and it is located between the backplane and the back layer of glue. Between the films, the adhesive film of the rear layer tends to overflow to the front of the mirror reflection part, forming a partial shading, affecting the reflection effect of the mirror reflection part 51 and reducing the power generation efficiency.
