Title An experimental study of the characteristics of solar cells
Abstract Solar energy is a kind of clean and inexhaustible energy sources. It is of great significance to solve the energy crisis the world is facing. Because of this, the study of solar cells has attracted extensive attention worldwidely. It is crucial to measure the paprameters of solar cells accurately for the investigation in improving conversion efficiency. Here we introduce the working principle of solar cells,the main physical parameters that determine the working performance of solar cells, the methods to measure the parameters and simply summarizes the research progress and the main technical problems we facing in this field at present. We measure the performance parameters of three kinds of solar cells including monocrystalline silicon solar cells, polycrystalline silicon solar cells and a-Si solar cells with ZKY-SAC-I, and then we analyze the dark I-V characteristics, the output power and the conversion efficiency of solar cells comparatively. In view of the simple structure and low efficiency of the cells we measured, some recent efforts to improve efficiency are summaried．
