Triple Layer Antireflection Design Concept for the Front Side of c-Si Heterojunction Solar Cell Based on the Antireflective Effect of nc-3C-SiC:H Emitter Layer

Table 1

Comparative result of the total reflectance and the total absorbance in each layer with different AR coating schemes and emitter layer for flat SHJ solar cell. The thicknesses of AR and emitter are optimized values.
