A method for manufacturing a passivation stack on a crystalline silicon solar cell device. The method includes providing a substrate comprising a crystalline silicone layer such as a crystalline silicon wafer or chip, cleaning a surface of the crystalline silicon layer by removing an oxide layer at least from a portion of one side of the crystalline silicon layer, depositing, on at least a part of the cleaned surface, a layer of silicon oxynitride, and depositing a capping layer comprising a hydrogenated dielectric material on top of the layer of silicon oxynitride, wherein the layer of silicon oxynitride is deposited at a temperature from 100&#xb0; C. to 200&#xb0; C., and the step of depositing the layer of silicon oxynitride includes using NO and SiHas precursor gasses in an Nambient atmosphere and depositing silicon oxynitride with a gas flow ratio of NO to SiHbelow 2.

The invention relates to a non-invasive method to diagnose the changes of molecular structures of organism tissues from body surface and a dedicated apparatus. The apparatus is comprised of a Fourier Transform infrared spectrometer and a set of additional accessories. Said additional accessories include a mid-IR fiber optics sampling attachment, a fiber coupling part, and an infrared detector part. The detection method is comprised of placing the ATR probe of the dedicated apparatus on the skin surface of a region to be tested, and scanning more than one time in which the resolution of the apparatus is 1-32 cmand the range of the spectrum is 800-4000 cm. It is possible to detect changes in molecular structures of living biological tissues in the early stages of cancer, and testees will not feel uncomfortable during testing. The method is easy to operate, quick, accurate, and it doesn't harm the body.
