The dependency of the relative absorption on the angle of incidence for a continuous silicon film, a continuous silicon film with 50 nm Si3N4 antireflection coating and for a LF array with a period of 500 nm, Dt = 400 nm an Db = 100 nm and with a 50 nm Si3N4 antireflection coating (all heights are 2 μm).
These wavelengths are chosen as these are located at the vicinity of the peak power of the solar spectrum. (a), wavelength 540 nm. (b), wavelength 600 nm.
