Application of solar photovoltaic

Thin-film photovoltaics (TFPV) is being developed as a cheaper alternative to silicon-based wafers. There are three major types of thin-film photovoltaics, named according to the composition of their effective layers: silicon thin-film, II-VI (mainly cadmium antimonide), and CIGS(gallium selenide copper). Each effective layer film is used on a transparent conductive oxide film, and the substrate can be glass or metal. It is very important to accurately understand the thickness and composition of the effective layer when measuring it. If it is too thin, it will affect efficacy and durability, while if it is too thick, it will increase costs. Incorrect composition can significantly reduce the efficacy and manufacturing output of the product. Fil

Dielectrics for thin film applications

Tens of thousands of electrolyte films are used in optics, semiconductors, and dozens of other industries, and Filmetrics' instruments can measure almost all films. Common dielectrics include: silicon dioxide; One of the simple materials, mainly because of its non-absorbency in most spectra (k=0), and it is very close to the stoichiometric ratio (that is, silicon: oxygen is very close to 1:2). Silica grown on heat has a spectral reaction specification and is usually used as a standard for thickness and refractive index. Filmetrics can measure the thickness of silica ranging from 3nm to 1mm

Amorphous polycrystalline silicon for thin-film applications

Amorphous polycrystalline silicon: Silicon exists in both amorphous and crystalline forms, and between the two forms is partially crystalline silicon. Some crystalline silicon is also called polycrystalline silicon. The optical constants (n and k) of amorphous silicon and polycrystalline silicon require precise thickness measurements under different deposition conditions. When measuring the thickness, roughness and the possible weathering of silicon film crystallization are also taken into consideration. The complex measurement program provided by the Filmetrics device simultaneously measures and outputs each required silicon thin film parameter, and ";" "One-click" The result is out. Measurement example: Polycrystalline silicon is widely used in silicon-based electronic devices. The efficiency of these devices is
