Description
技术领域 technical field

背景技术 Background technique
随着对化石燃料、天然气等自然资源的需求增加，以及传统能源使用对环境带来的严重破坏，人们对可再生清洁资源的研究越来越重视，希望可再生清洁资源可以改善当前传统能源带来的问题。在所有可再生清洁资源中，太阳能无污染、廉价等优势成为了人们关注的焦点。 With the increasing demand for natural resources such as fossil fuels and natural gas, and the severe damage to the environment caused by the use of traditional energy, people are paying more and more attention to the research of renewable clean resources, hoping that renewable clean resources can improve the current traditional energy belt. to the problem. Among all renewable and clean resources, the advantages of solar energy, such as pollution-free and cheap, have become the focus of attention.
近十几年来，在各种太阳能电池的开发研究过程中，都需要对太阳能电池的性能进行测试。在传统测试中，将太阳能电池样品自然放置于太阳光氙灯模拟照射下，通过计算机连接数据采集设备，来完成信号的转换与采集，从而达到测试太阳能电池样品性能的目的。 In the past ten years, in the development and research process of various solar cells, it is necessary to test the performance of the solar cells. In the traditional test, the solar cell sample is naturally placed under the simulated sunlight xenon lamp, and the data acquisition equipment is connected to the computer to complete the signal conversion and collection, so as to achieve the purpose of testing the performance of the solar cell sample.
在太阳能电池样品的测试过程中为了实验数据的准确性，应当尽可能在暗室中操作；为了检测均匀性，希望对太阳能电池的不同区域进行测试而且不破坏整个样品。同时为了能够得到更精确的数值，可以通过测试太阳能样品不同更小的区域，最后求取平均值。 During the testing of solar cell samples, for the accuracy of experimental data, it should be operated in a dark room as much as possible; in order to test the uniformity, it is hoped that different regions of the solar cell should be tested without destroying the entire sample. At the same time, in order to obtain more accurate values, different and smaller areas of solar samples can be tested, and finally the average value can be calculated.
但是传统的测试过程中，太阳能电池的底片（常用FTO（氟掺杂锡氧化物）、ITO（氧化铟锡））不易分割为更小区域，小面积电极制备困难、欧姆接触较差。此外，部分实验样品度易发生形变，柔性大，固定容易滑动出现导致对样品的破坏。 However, in the traditional test process, the backsheet of solar cells (commonly used FTO (fluorine-doped tin oxide), ITO (indium tin oxide)) is not easy to be divided into smaller areas, and the preparation of small-area electrodes is difficult and the ohmic contact is poor. In addition, some experimental samples are easily deformed and flexible, and the fixation is easy to slide and cause damage to the sample.
