英文摘要It is important for Si solar cells to make full use of sunlight by minimizing spectral mismatch and reducing light reflection. Herein, ZnO nanoparticles coating, which has a dual function of antireflection and down-shifting, was prepared on Si substrate by the sol-gel method. The obtained ZnO coating has a uniform structure, low roughness, and good mechanical robustness. The ZnO coating on Si substrate has a remarkable antireflection enhancement effect, with an average reflectance was 10.83% at the 400 similar to 1100 nm band, which was 19.43% lower than that of the uncoated Si substrate. Moreover, ZnO nanoparticles coatings can absorb light before 400 nm and convert it to about 527 nm, showing an apparent down-shifting effect. The photocurrent of the coated solar cells was significantly improved, with an average photocurrent increase of 21% at 300-800 nm. The coatings prepared herein with both antireflection and down-shifting luminescence properties are important for improving the photovoltaic conversion efficiency of solar cells.
