多晶硅太阳电池绒面反射率的研究

主要研究多晶硅片在未加缓蚀剂的酸腐蚀溶液中制绒后，绒面反射率对电池片效率的影响；用RENA制绒机自带反射仪对硅片绒面反射率进行检测，用3D显微镜对多晶硅片绒面的形貌进行观察和检测分析。实验过程中，按照工业生产的实际模型，确定了多晶硅片制绒后，绒面的最佳反射率范围是18．0％～18．5％，合理范围是18％～19％；并分析了绒面反射率影响电池片效率的原因。

An Automatic Dust Removal Device Based on SCM for Solar Panels

This paper introduces a set of automatic dust removal device for street lamp solar panels. The device realizes the automatic dust removal for street lamp solar panels by three steps consisting of data acquisition, automatic control and mechanical dust removal. Our scheme is as follows, according to the comparison between the actual power generation and the relatively ideal condition of power generation of solar panels, we selectively conduct dust removal operation to panels. The paper demonstrates the feasibiliW of the technology based on the example of street lamp solar panels （40w）. According to the calculation, the solar panels equipped with our device will greatly improve the power generation efficiency of solar panels, which means there will be 32 more degrees generated every year. Extension and application of the technique device will be beneficial for the improvement of solar panels power generation efficiency and the extension of the service life of the panels.
