Absorption of the optimum structure with a ZnO layer. a The schematic drawing of a typical 3D optical model with a ZnO layer between the a-Si and Ag layers; the thickness of the a-Si and Ag layers is 160 and 200 nm, respectively. Simulated absorption of the a-Si layer (b) and parasitic absorption of the Ag layer (c) as a function of the illumination wavelength and thickness of the ZnO layer
