Experimental Study on the Effect of Lunar Dust Deposition on Short-Circuit Current of Solar Cell

In this paper,the relationships between solar cell short-circuit current and important experimental parameters are studied by ground simulation experiments. The results show that,due to the angle loss,the relationship between the short-circuit current of solar cells with or without lunar dust deposition and the light incident angle cannot be approximated by conventional cosine function,and the angle loss phenomenon becomes more obvious with the increasing amount of lunar dust deposited on the surface of solar cells. Secondly,at any light incident angle,the relationship between the short-circuit current of the solar cell and the quality of the deposited lunar dust can be fitted exponentially,but a large incident angle will lead to serious attenuation of the sensitivity of the solar cell. Finally,under the same deposition quality,the smaller the particle size of the lunar dust is,the stronger the shading effect of lunar dust on solar cells,which is due to the larger specific surface area of small particles of lunar dust and smaller gaps between particles.
