背景技术Background technique
在太阳能的有效利用项目当中：光电利用是近些年来发展最快，最具活力的研究领域。 一般太阳能电池的制作主要是以半导体材料为基础，利用光电材料吸收光能后发生光电转换反应发电。根据所用材料的不同，太阳能电池可分为：1、硅太阳能电池；2、以无机盐如砷化镓III-V化合物、硫化镉、铜铟硒等多元化合物为材料的太阳能电池；3、以功能高分子材料制备的太阳能电池；4、纳米晶太阳能电池等。Among the projects of effective utilization of solar energy: photovoltaic utilization is the fastest growing and most dynamic research field in recent years. Generally, the production of solar cells is mainly based on semiconductor materials, which use photoelectric materials to absorb light energy and generate photoelectric conversion reactions to generate electricity. According to the different materials used, solar cells can be divided into: 1. Silicon solar cells; 2. Solar cells made of inorganic salts such as gallium arsenide III-V compounds, cadmium sulfide, copper indium selenide and other multi-component compounds; 3. Solar cells made of Solar cells made of functional polymer materials; 4. Nanocrystalline solar cells, etc.
现有技术工作效率最高的是以III-V族半导体无机材料为原材料的产品。 例如:砷化镓/锗单一接面型的量子井陷晶结构，其光电转换效率可达>18 % ；而多重接面量子井陷晶结构之太阳电池，例如: 磷化铟镓/砷化镓/锗，其光电转换效率可高达>30 %。目前应用最广，以硅为主：包括非晶硅，光电转换效率约9 %；多晶硅，光电转换效率约14 %；单晶硅，光电转换效率约17 %。虽然在价格上，VI族元素Si要比III-V族半导体GaAs便宜，但其制造的价格，与高分子有机太阳能电池相比，还是昂贵许多；而在应用上，质轻又无破裂之虞的全塑化有机太阳能电池可经由印刷的加工实现，除价格降低外，更适合可携式电子产品的需求，且在室内或阴天均能正常使用（这是硅质太阳能电池所无法达到的），使得它的实用性及市场应用广度更加提升。The product with the highest working efficiency in the prior art is based on III-V group semiconductor inorganic materials as raw materials. For example: gallium arsenide/germanium single-junction quantum well trap structure, its photoelectric conversion efficiency can reach >18%; and solar cells with multi-junction quantum well trap structure, such as: indium gallium phosphide/arsenide Gallium/germanium, whose photoelectric conversion efficiency can be as high as >30%. At present, silicon is the most widely used, including amorphous silicon, with a photoelectric conversion efficiency of about 9%; polycrystalline silicon, with a photoelectric conversion efficiency of about 14%; and monocrystalline silicon, with a photoelectric conversion efficiency of about 17%. Although in terms of price, the group VI element Si is cheaper than the III-V group semiconductor GaAs, but its manufacturing price is still much more expensive than polymer organic solar cells; and in application, it is light in weight and has no risk of rupture. The fully plasticized organic solar cells can be realized by printing. In addition to lower prices, they are more suitable for the needs of portable electronic products, and can be used normally indoors or on cloudy days (this is something that silicon solar cells cannot achieve. ), making its practicability and market application breadth more enhanced.
太阳能电池是一项关键技术，会推进更清洁的能源生产。但是太阳能电池的成本问题，降低了太阳能技术的经济竞争力。为克服这个问题，薄膜太阳能电池是目前广泛应用的技术，可以大量减少昂贵半导体材料的使用量，但薄膜太阳能电池的光吸收量较低，性能比不上传统的太阳能电池。Solar cells are a key technology that will advance cleaner energy production. But the cost of solar cells has reduced the economic competitiveness of solar technology. To overcome this problem, thin-film solar cells are currently widely used technology, which can greatly reduce the use of expensive semiconductor materials, but thin-film solar cells have low light absorption, and their performance is not as good as traditional solar cells.
薄膜太阳能模块是由玻璃基板、金属层、透明导电层、电器功能盒、胶合材料、半导体层等所构成的。有机-无机复合太阳能电池是基于有机共轭高分子-无机纳米晶复合材料体系的太阳能电池，因同时具有机高分子材料成膜性好，能级结构及带隙易于调节，可以通过湿法制备低成本、大面积、柔性太阳能电池器件以及无机纳米晶材料高稳定性，高迁移率，可构筑有序纳米结构等优点，而成为近年来太阳能电池领域的研究热点。金属纳米粒子可以引导光更好地进入太阳能电池，防止光逃逸。在传统的“厚膜”太阳能电池中，纳米粒子没有什么效果，因为所有的光线吸收都是通过这种膜，这就依赖它的厚度。然而，对于薄膜而言，纳米粒子就可以发挥很大作用。它们的散射增加了光停留在薄膜中的时间，使总体吸收的光达到一种水平，可以媲美传统的太阳能电池。Thin-film solar modules are composed of glass substrates, metal layers, transparent conductive layers, electrical functional boxes, adhesive materials, semiconductor layers, etc. Organic-inorganic composite solar cells are solar cells based on the organic conjugated polymer-inorganic nanocrystalline composite material system. Because organic polymer materials have good film-forming properties, the energy level structure and band gap are easy to adjust, they can be prepared by wet methods. Low-cost, large-area, flexible solar cell devices and inorganic nanocrystalline materials with high stability, high mobility, and the ability to construct ordered nanostructures have become research hotspots in the field of solar cells in recent years. Metal nanoparticles can guide light into solar cells better and prevent light from escaping. In conventional "thick-film" solar cells, nanoparticles have little effect because all light absorption is through the film, which depends on its thickness. For thin films, however, nanoparticles can do a lot. Their scattering increases the time that light stays in the film, bringing the overall light absorption to a level comparable to conventional solar cells.
铝与银纳米粒子在可见部分的频谱中，可以很好地聚焦光线进入太阳能电池。但是光学共振也会导致纳米粒子吸收光，这就意味着太阳能电池的效率会较低。银纳米粒子共振正好处在太阳能电池关键吸收光谱部分，所以光的吸收是相当可观的。铝纳米粒子共振超出了太阳能电池关键光谱部分。对能量的损耗较小，此外，铝粒子很容易钝化，虽然会改变形状和大小，钝化后纳米粒子属性变化很小。纳米粒子有凹凸不平的表面，散射光线会更多地进入广谱波长范围。这会带来更大的吸收，从而提高电池的整体效率。Aluminum and silver nanoparticles in the visible part of the spectrum do a good job of focusing light into solar cells. But the optical resonance also causes the nanoparticles to absorb light, which means the solar cell will be less efficient. The resonance of silver nanoparticles is just in the key absorption spectrum part of solar cells, so the absorption of light is considerable. Aluminum nanoparticles resonate beyond critical spectral parts for solar cells. The loss of energy is small. In addition, aluminum particles are easily passivated. Although the shape and size will change, the properties of the nanoparticles will change little after passivation. Nanoparticles have uneven surfaces that scatter light more into a broad-spectrum wavelength range. This results in greater absorption, which increases the overall efficiency of the cell.
由于高技术材料芳香族均苯型聚酰亚胺（PI）树脂具有不溶、难熔、最高级别的耐热性、耐寒性、抗氧化性、耐辐射性、耐化学性、良好的机械和电气特性，被广泛应用于诸多领域。特别是光学透明的ＰＩ膜在一些领域中有特殊应用，如柔性太阳能辐射保护材料、太阳能电池基板材料、柔性透明导电膜基板材料、液晶显示器的取向膜材料、通讯领域中的光波导材料和平面光波电路的光学半波板等。Due to the high-tech material aromatic polyimide (PI) resin is insoluble, refractory, the highest level of heat resistance, cold resistance, oxidation resistance, radiation resistance, chemical resistance, good mechanical and electrical properties and are widely used in many fields. In particular, optically transparent PI films have special applications in some fields, such as flexible solar radiation protection materials, solar cell substrate materials, flexible transparent conductive film substrate materials, alignment film materials for liquid crystal displays, optical waveguide materials and planar materials in the communication field. Optical half-wave plates for light wave circuits, etc.
大多数芳香族ＰＩ由于存在高度共轭结构和／或分子间形成电荷转移络合物（ＣＴＣ）使其在可见光区域有强烈的吸收，呈浅黄色或深棕色，限制了其在光学领域的应用。由于其具有较高的软化温度和有限的可溶性，因此存在加工困难的问题。ＰＩ的加工多是以聚酰胺酸溶液形式进行，浇注成膜后经热酰亚胺化得到ＰＩ薄膜。这种方法简单易行，但存在一些固有的缺点，如聚酰胺酸的贮存期较短，在酰亚胺化过程中由于产生挥发性副产物（如水）而易产生缺陷。为了克服这些缺陷，人们就可溶性和可加工性ＰＩ做了很多研究。可溶解性允许以ＰＩ形式加工，避免了加工聚酰胺酸所带来的一些问题，这对于微电子和光学领域应用是尤为重要。Due to the existence of highly conjugated structures and/or the formation of charge-transfer complexes (CTCs) between molecules, most aromatic PIs have strong absorption in the visible light region and appear light yellow or dark brown, which limits their applications in the field of optics. . Due to its high softening temperature and limited solubility, it presents processing difficulties. The processing of PI is mostly carried out in the form of polyamic acid solution, and the PI film is obtained by thermal imidization after casting into a film. This method is simple and easy to implement, but there are some inherent disadvantages, such as the short shelf life of polyamic acid, and it is prone to defects due to the generation of volatile by-products (such as water) during the imidization process. In order to overcome these shortcomings, many studies have been done on the solubility and processability of PIs. Solubility allows processing in the PI form, avoiding some of the problems associated with processing polyamic acid, which is particularly important for microelectronic and optical applications.
从分子结构设计上增加ＰＩ透明性的原则是避免或减少共轭单元，减少分子内或分子间的传荷作用，常用方法有：（１）引入含氟基团；（２）引入体积较大的取代基，如圈形结构及其他大的侧基；（３）在联苯的２，２′－位引入取代基以产生非共平面结构，破坏较大范围的共轭；（４）引入脂肪，尤其是脂环结构单元；（５）采用能使主链弯曲的单体，如３，４′－和３，３′－二酐，间位取代的二胺等。The principle of increasing the transparency of PI from the design of molecular structure is to avoid or reduce conjugated units, and reduce the intramolecular or intermolecular load transfer effect. The common methods are: (1) introducing fluorine-containing groups; (2) introducing large volume Substituents, such as ring structures and other large side groups; (3) Introduce substituents at the 2,2′-position of biphenyl to produce non-coplanar structures, destroying a wide range of conjugation; (4) Introduce Fat, especially alicyclic structural units; (5) Use monomers that can bend the main chain, such as 3,4'- and 3,3'-dianhydrides, meta-substituted diamines, etc.
改善ＰＩ溶解性的方法有两种：一种是引入对溶剂具有亲和性的结构；另一种是打乱大分子链的有序性和对称性，减弱分子链间的相互作用使聚合物的结构变得“松散”，具体方法有：（１）引入含氟、硅、磷的基团或羟基；（２）引入“圈”形结构；（３）引入侧基；（４）使大分子链弯曲；（５）引入脂肪结构等。There are two ways to improve the solubility of PI: one is to introduce a structure with affinity to the solvent; the other is to disrupt the order and symmetry of the macromolecular chains, weaken the interaction between the molecular chains and make the polymer The structure becomes "loose", the specific methods are: (1) introducing fluorine, silicon, phosphorus groups or hydroxyl groups; (2) introducing "ring" structure; (3) introducing side groups; (4) making large Molecular chain bending; (5) introduction of fat structure, etc.

本发明的有益效果：纳米金属铝粒子很容易钝化，虽然会改变形状和大小，钝化后纳米粒子属性变化很小。纳米粒子有凹凸不平的表面，散射光线会更多地进入广谱波长范围。这会带来更大的吸收，从而提高电池的整体效率。金属铝纳米粒子的散射增加了光停留在薄膜中的时间，使总体吸收的光达到一种水平，可以媲美传统的太阳能电池。经使用本发明光固化聚酰亚胺膜处理的薄膜太阳能电池比未经本光固化聚酰亚胺膜的薄膜太阳能电池性能提高3-15%。薄膜太阳能电池使用该用光固化聚酰亚胺膜后，金属铝纳米粒子可以引导光较好地进入太阳能电池，防止光逃逸。解决传统的“厚膜”太阳能电池中，纳米粒子没有什么效果而所有的光线吸收必需依赖厚度解决的问题。Beneficial effects of the invention: the nano metal aluminum particles are easy to passivate, although the shape and size will be changed, the properties of the nano particles change little after passivation. Nanoparticles have uneven surfaces that scatter light more into a broad-spectrum wavelength range. This results in greater absorption, which increases the overall efficiency of the cell. Scattering by the metallic aluminum nanoparticles increases the time that light stays in the film, bringing the overall light absorption to a level comparable to conventional solar cells. The performance of the thin film solar cell treated with the photocurable polyimide film of the invention is 3-15% higher than that of the thin film solar cell without the photocurable polyimide film. After the thin-film solar cell uses the light-cured polyimide film, the metal aluminum nanoparticles can guide light into the solar cell and prevent light from escaping. Solve the problem that in traditional "thick film" solar cells, nanoparticles have little effect and all light absorption must rely on thickness to solve the problem.
