【摘要】：太阳能是人类最早认识并加以利用的能源之一。20世纪以来，随着社会经济的发展和人民生活水平的提高，对能源的需求量不断增长。太阳能资源具有数量巨大、时间长久、普照大地、清洁安全的优点，具有很大的开发潜能。同时太阳能有分散性、间断性和不稳定性、效率低和成本高的缺点，制约着太阳能的普及使用，这需要科研设计来克服。针对太阳能电池应用的客观前景，因此以太阳能电池的特性研究及应用设计为论文课题，，分四大部分。第一部分：太阳能资源。第二部分：太阳能电池的原理及当前市场状况。第三部分：太阳能电池的特性研究：包括硅太阳能电池的暗伏安特性测试、开路电压，短路电流与光强关系测量、太阳能电池输出特性测试、环境因素对太阳能电池性能影响。第四部分：太阳能自动跟踪系统：因为太阳的位置会随时间变化而改变，或者太阳能供电系统自身需要移动，所以在太阳能供电系统中很大一个问题是太阳能板能否正确地朝向太阳，使太阳能转化效率达到最高。因此太阳能自动跟踪系统对于太阳能发电尤为重要。该论文最后以太阳能自动跟踪系统为研究课题，设计了比较实用的三种太阳能自动跟踪系统：单轴步进式、光电比较法、利用经纬度跟踪法。
[Abstract]:Solar energy is one of the earliest energy sources recognized and utilized by human beings. Since the 20th century, with the development of social economy and the improvement of people's living standard, the demand for energy has been increasing. Solar energy resources have the advantages of large quantity, long time, clean and safe, and have great development potential. At the same time, solar energy has the disadvantages of dispersion, discontinuity and instability, low efficiency and high cost, which restricts the popularization and use of solar energy, which needs to be overcome by scientific research and design. In view of the objective prospect of solar cell application, this paper focuses on the research and application design of solar cell, which is divided into four parts. The first part: solar energy resources. The second part: the principle of solar cells and the current market situation. The third part: the characteristics of solar cells: including the dark volt-ampere characteristics of silicon solar cells, open circuit voltage, short circuit current and light intensity relationship measurement, solar cell output characteristics test, environmental factors on the performance of solar cells. Part IV: solar automatic tracking system: because the position of the sun changes over time, or the solar power supply system itself needs to move. Therefore, a big problem in solar power supply system is whether the solar panels are correctly oriented towards the sun, so that the conversion efficiency of solar energy can reach the highest. Therefore, solar automatic tracking system is particularly important for solar power generation. In the end of this paper, three kinds of solar automatic tracking systems are designed, which are single axis step, photoelectric comparison and longitude and latitude tracking.
