What is the work function of ITO?
What is the work function of ITO?
Work function of ITO has been reported in the range of 4.2–5 eV.
What is fluorine doped tin oxide?
Abstract: Fluorine-doped tin oxide (FTO) is one of the most studied and established materials for transparent electrode applications. High-quality SnO2 quantum dots are synthesized with a tuneable fluorine amount up to ~10% atomic, and their structural, morphological and optical properties are fully characterized.
How do you make fluorine doped tin oxide?
Fluorine doped tin oxide (FTO) thin films were prepared by using Ammonium Fluoride (NH4F) and DBTDA. These two solutions were mixed and finally get the Fluorine doped with tin oxide. The solution then proceeds to spray pyrolysis process to produce the FTO substrate.
Why is FTO used in solar cells?
A transparent electrode is essential for solar cells as it allows incoming light to reach the photoactive layer. Transparent conductive oxides (TCO) such as indium tin oxide (ITO) and fluorine doped tin oxide (FTO) are well-suited for this purpose due to their transparent and conductive nature.
Is Ito a semiconductor?
Indium tin oxide (ITO) is a well-known n-type degenerate semiconductor with a wide variety of electronic and optoelectronic applications.
What is FTO substrate?
FTO (Fluorine-doped Tin Oxide) glass is a transparent conductive metal oxide that can be used in the fabrication of transparent electrodes for thin film photovoltaics, such as: organic photovoltaic, amorphous silicon, cadmium telluride, dye-sensitised solar cells, and hybrid perovskites.
What is TCO in solar cell?
Overview. Transparent conductive oxides (TCO) are doped metal oxides used in optoelectronic devices such as flat panel displays and photovoltaics (including inorganic devices, organic devices, and dye-sensitized solar cells). To date, the industry standard in TCOs is ITO, or indium tin oxide.
Is FTO N type?
So, FTO and ITO in this work are n-type semiconductors. absorption coefficient α for various wavelengths can be calculated. According to the ellipsometry measurement, film thickness of FTO and ITO are 848.11 nm and 231.75 nm respectively.
What is work function of a metal?
Work function of a metal is the minimum amount of energy required by an electron to escape from metal surface .
Does work function depend on metals?
Note: Work function depends upon the structure and chemical composition of a surface. On the other hand side, platinum is the highest knowing metal work function and the lowest work function metal is cesium….
| ELEMENTS | WORK FUNCTION (eV) |
|---|---|
| Selenium | 5.11 |
| Silver | 4.26-4.73 |
| Sodium | 2.28 |
| Uranium | 3.6 |
Is ITO a metal?
In the infrared region of the spectrum it acts as a metal-like mirror. Indium tin oxide is one of the most widely used transparent conducting oxides because of its electrical conductivity and optical transparency, as well as the ease with which it can be deposited as a thin film.
