技术领域technical field
本发明属于太阳能电池领域，具体涉及一种低工艺成本的薄膜太阳能柔性聚合物衬底。The invention belongs to the field of solar cells, in particular to a thin-film solar flexible polymer substrate with low process cost.
背景技术Background technique
从太阳能电池生产技术的成熟度来区分，太阳能电池可以分为：晶体硅太阳能电池和薄膜太阳能电池。晶体硅太阳能电池是建立在高质量的单晶硅材料和相关的一系列成熟的加工处理工艺基础上，由于其技术相对稳定成熟，光电转换效率高，目前占据着80％以上的太阳能电池市场，但是晶体硅太阳能电池的使用成本很高，光伏发电使用成本约为1.18元/度，远大于煤电的0.5元/度。与晶体硅太阳能电池相比，薄膜太阳能电池多采用非晶硅、多晶硅薄膜或者铟硒化镉等薄膜材料实现光电转换，材料用量少、价格便宜、生产自动化程度高，在原料和制造工艺中大大降低了成本，更重要的一点是，薄膜太阳能电池可以使用柔性衬底，大大扩展了太阳能电池的应用范围，为太阳能电池的发展提供了更广阔的空间。According to the maturity of solar cell production technology, solar cells can be divided into: crystalline silicon solar cells and thin film solar cells. Crystalline silicon solar cells are based on high-quality monocrystalline silicon materials and a series of related mature processing techniques. Due to their relatively stable and mature technology and high photoelectric conversion efficiency, they currently occupy more than 80% of the solar cell market. However, the cost of using crystalline silicon solar cells is very high, and the cost of photovoltaic power generation is about 1.18 yuan/kWh, which is much higher than the 0.5 yuan/kWh of coal power. Compared with crystalline silicon solar cells, thin-film solar cells mostly use amorphous silicon, polycrystalline silicon thin films or indium cadmium selenide thin-film materials to achieve photoelectric conversion, with less material consumption, cheaper prices, and a high degree of production automation. The cost is greatly reduced, and more importantly, thin-film solar cells can use flexible substrates, which greatly expands the application range of solar cells and provides a broader space for the development of solar cells.
但是，目前大规模制造柔性薄膜太阳能电池的工艺均采用绕卷式镀膜方式，生产设备造价昂贵、工艺复杂，导致成本较高，与晶体硅太阳能电池相比没有性价优势，制约了其产能和应用。同时，绕卷式镀膜方式完全放弃了已经成熟了的薄膜太阳能电池的刚性衬底技术和设备，会造成较大的浪费。However, the current large-scale manufacturing of flexible thin-film solar cells adopts the roll-to-roll coating method. The production equipment is expensive and the process is complicated, resulting in high costs. Compared with crystalline silicon solar cells, there is no cost-effective advantage, which restricts its production capacity and application. At the same time, the roll-to-roll coating method completely abandons the mature rigid substrate technology and equipment of thin-film solar cells, which will cause great waste.

对比例6Comparative example 6
市售铜铟硒柔性薄膜太阳能电池及其柔性衬底。Commercially available copper indium selenide flexible thin film solar cells and their flexible substrates.
分别测试实施例1-2和对比例1-6中各柔性衬底的透光率和由其制备的铜铟硒柔性薄膜太阳能电池的光电转化效率，每个柔性聚合物衬底和薄膜太阳能电池制作了三批，每批包括20-25个相同工艺制作的样品，每个样品均进行透光率和效率测试，去除其中异常数据后求平均值，分别记录于表1中。Test respectively the light transmittance of each flexible substrate in Examples 1-2 and Comparative Examples 1-6 and the photoelectric conversion efficiency of the copper indium selenide flexible thin film solar cell prepared therefrom, each flexible polymer substrate and thin film solar cell Three batches were produced, and each batch included 20-25 samples made by the same process. Each sample was tested for light transmittance and efficiency, and the average value was calculated after removing abnormal data, which were recorded in Table 1.
通过表1中的数据能够清晰的看出，按照本发明所制备的柔性衬底的透光性极好，达到90％以上，而且铜铟硒柔性薄膜太阳能电池效率达到17.5％以上，就国内而言具有非常突出的优势；通过对比例1可以看出，尽管刚性基底最终会与薄膜太阳能电池分离，但是基底的选择对电池的性质依然具有重要的影响；通过对比例2-5分别对剥离层和聚合物衬底中的组分进行了调整和改变，可以发现一旦改变其中任一组分，衬底的透光率都会下降，甚至由其制备的薄膜电池的转化效率也会降低，各组分在柔性衬底的制备过程中产生了协同作用，只有通过彼此的相互作用才能有效增强其透光率，尤其是剥离层，尽管最后会被出掉，但是它的组成依旧对产品质量具有重要作用；通过实施例1和对比例6的测试结果比较，可以发现，本发明所制备的柔性衬底及薄膜太阳能电池在衬底透光率和转化效率上较同类产品有很大提高。It can be clearly seen from the data in Table 1 that the light transmittance of the flexible substrate prepared according to the present invention is excellent, reaching more than 90%, and the efficiency of the copper indium selenide flexible thin film solar cell reaches more than 17.5%, which is relatively high in China. It can be seen from Comparative Example 1 that although the rigid substrate will eventually be separated from the thin-film solar cell, the selection of the substrate still has an important impact on the properties of the battery; and the components in the polymer substrate have been adjusted and changed. It can be found that once any component is changed, the light transmittance of the substrate will decrease, and even the conversion efficiency of the thin film battery prepared by it will decrease. Each group In the preparation process of the flexible substrate, there is a synergistic effect. Only through the interaction with each other can the light transmittance be effectively enhanced, especially the peeling layer. Although it will be removed in the end, its composition is still important to the product quality. Effect: By comparing the test results of Example 1 and Comparative Example 6, it can be found that the flexible substrate and thin-film solar cell prepared by the present invention have greatly improved substrate light transmittance and conversion efficiency compared with similar products.
