sunlight from the metals, but they can also serve the function of antireflectioncoating (ARC) films, given proper design of the film thickness. A ZnO thin film with appropriate doping could potentially act as the emitter with a Si substrate base to form a heterostructure solar cell. Therefore, in the most

) was evaluated at a carrier injection level corresponding to 1-sun illumination, which led to values below 10 cm/s. Reflectance values below 2% were measured on textured samples over the wavelength range of 450–1000 nm.

single 90 nm thick Al2O3 film. Therefore, the latter represents the better option as an antireflectioncoating compared to Al2O3/a-SiCx stacks. This result is supported by the reflectance measurements of Al2O3 films with different thicknesses and Al2O3/a-SiCx stacks on polished and textured c-Si
. Inserting an a-SiCx capping layer by PECVD technique can overcome this drawback. In this study, we have investigated different combinations of layers that provide good antireflection properties while maintaining a total film thickness of 75 nm. In addition to the passivation, a high-quality antireflection
