Nano-SiC薄膜对太阳能电板转换效率影响的研究

Research of the Nano-SiC Film on the Conversion Efficiency of Solar Panel

采用丝网印刷法在太阳能电板超白玻璃表面制备出不同厚度的Nano-SiC薄膜,研究了Nano-SiC薄膜厚度对光子透过率和户外太阳能电板转换效率的影响。结果表明,经过两层Nano-SiC薄膜处理后,超白玻璃的平均光子透过率提高了12%左右;同时Nano-SiC薄膜可以降低户外太阳能电板转换效率的降低速率,经过两层Nano-SiC薄膜处理后太阳能电板的转换效率降低速率约为未处理时的0.3倍。

Different-layer Nano-SiC film was fabricated on solar panel by sol-gel screen-printing method. The photons transmittance of different-layer Nano-SiC film was studied, and also the conversion efficiency of solar panel. The test result indicated that the average photons transmittance of ultra clear glass was increased by about 12% by fabricating two layers Nano-SiC film on its surface. The conversion efficiency decreasing rate of the solar panels slowed down by preparing Nano-SiC films on it, the decreasing rate was about 0. 3 times of the solar panel that did not fabricate Nano-SiC film.
