Improved Efficiency of Graphene/Si Heterojunction Solar Cells by Optimizing Hydrocarbon Feed Rate
Figure 1
(a) Optical transmission spectra of different graphene samples. Inset is the enlarged spectra of the parts highlighted with light yellow color. (b) A schematic diagram of the solar cell device configuration. In this kind of device, photo-generated holes (h+) and electrons (e-) are driven by the built-in electric field into graphene and -Si, respectively.
