摘要：
In order to analyze the influence of the dust morphology and density on system performance，the experimental test platform of solar photovoltaic/thermal（PV/T）system is built outdoors. The results show that the photothermal conversion efficiency of solar PV/T system is mainly affected by the morphology of dust，while the photoelectric conversion efficiency is mainly affected by the density of dust. Compared with loose dust，the bonding dust has a greater impact on the photothermal conversion efficiency and comprehensive efficiency. When the density of loose dust changes from 0 to 33.79 g/m2，the decline rate of photothermal efficiency is only 2.32% and the decline rate of photoelectric efficiency is 48.65% . In this experiment，the working temperature of photovoltaic cells are 53.99，52.92，50.73 and 55.58 益，respectively with the increase of the dust density，the trend of the working temperature of photovoltaic cells tends to decrease first and then increase. Therefore，a small amount of dust will not rise the working temperature of the photovoltaic cell and will not affect the normal operation of the solar PV/T system. © 2023 Science Press.
