Enhanced Visible Light Absorption by 3C-SiC Nanoparticles Embedded in Si Solar Cells by Plasma-Enhanced Chemical Vapor Deposition

Figure 8

Photoreflectance of the Si solar cell samples coated and embedded with 7, 10, 20, and 50 nm SiC nanoparticles. The PR of the (a) flat and (b) microtextured Si solar cells coated with 7–50 nm SiC nanoparticles, and (c) the microtextured Si solar cell where SiC nanoparticles are embedded in the Si thin film. The photoreflectance in the UV region greatly depends on the size of the SiC nanoparticles, with the exception of the 20 nm nanoparticles, and the photoreflectance in the IR region is reduced by the Si nanocrystals formed in the thin film deposition.
