碩士 === 遠東科技大學 === 機械工程研究所在職專班 === 107 === As the global energy crisis is increasing, the search for alternative energy sources is currently an extremely important issue. The use of silicon wafer solar cells to generate electricity is relatively low cost and relatively environmentally compared to other alternative energy sources. Analyzing and studying the photoelectric conversion efficiency of wafer solar cells has become a crucial issue in the industry. The gain not only reduces the production cost and price, but also increases market acceptance, and popularizes the use of more solar power in the world. It not only seeks solutions for the energy crisis, but also further enhances the environmental protection of the earth. In this experiment, we will analyze and monitor the production process of solar cells, and seek to reversely increase the conversion efficiency of solar cells at the same or lower cost, and accurately monitor the changes in cells efficiency and electrical properties. In the production of the screen, and grasp the best timing, let the screen due to the gradual exhaustion and the conversion efficiency drop critical point, at this point to replace the screen to achieve efficiency optimization, reduce industrial inefficient solar cell production Out, and can gain gains in manpower and rubber waste, to achieve the goal of reducing costs and improving conversion efficiency. In this study, it is found that the number of samples is 350pcs-450pcs, which can increase the efficiency of solar cells with the highest efficiency. The value of the cell is about 20%, and the average conversion efficiency can be increased the best 0.05%. At 450pcs or more, the efficiency will gradually decline. Therefore, if the sampling number is too large, the timing of controlling the network version will be gradually distorted. If the industry can adjust it from 350pcs to 450pcs, the actual perfect benefits can be obtained.
