The working principle of solar cells are set forth detailedly, and the physical model of amorphous silica-based thinfilm solar ceils are given. The output characteristics of amorphous silica-based thin-film modules are tested, and the stand-alone PV systems are designed and monitored, and the experimental results were analyzed. The results of outdoors tests show that the conversion efficiency of modules are consistent with the results measured in the laboratory, which proves the system designed with amorphous silica-based thin-film modules used in low irradiance zone has more high reliability and efficiency.
