What is TCO in solar cell?

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.

What is TCO coating?

Transparent conductive oxide coatings, commonly called TCO coatings, are a type of inorganic TCF (transparent conductive film) used in electronics. TCO coatings are transparent and electrically conductive and are often used in photovoltaics, LCDs (liquid crystal displays), OLEDs and touchscreens.

What is TCO thin film?

ABSTRACT. Transparent conductive oxides (TCO) have high optical transmission at visible wavelengths and electrical conductivity close to that of metals.

What is FTO substrate?

Fluorine-doped tin oxide (FTO) coated glass is electrically conductive and ideal for use in a wide range of devices, including applications such as opto-electronics, touch screen displays, thin film photovoltaics, energy-saving windows, RFI/EMI shielding and other electro-optical and insulating applications.

Why TCO is used in solar cell?

High mobility TCOs for high-efficiency solar cells At the front of the solar cells, these TCO layers act as the optically transparent electrode that allows photons into the solar cell and transports the photo-generated electrons to the external device terminals.

Why is silicon used in solar cells?

A number of PV cells aggregated in a confined panel act as a collector of solar energy. Silicon semiconductors are popular because they exhibit properties such as low weight volume ratio, extended life cycle, robustness and strength. Silicon semiconductors are easy to produce at low cost.

Why is ITO transparent?

It is the large ELECTRONIC band gap and not so high carrier density makes it transparent to visible light. ITO is not as conductive as metals, they do reflect light to, but this reflection only kicks in at longer wavelength (beyond visible light wavelength), therefore, they are transparent in the visible region.

What is ITO and FTO?

TCO such as Indium tin oxide (ITO) Coated Glass, Fluorine-doped tin oxide (FTO), Aluminium-doped zinc oxide (AZO), Antimony-doped tin oxide (ATO) used to make conductive substrate. In research and industry mainly ITO and FTO coated glass used.

What is FTO chemical?

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 FTO in solar cell?

What kind of substrates can be used for Ito?

Indium tin oxide coated glass is probably the most popular substrate for systems that need the conductivity and transparency provided by TCOs . ITO can be easily deposited on soda lime glass substrates as a high-quality thin film, and the industry has decades of experience with this material set.

What kind of material can be used as a conductive substrate?

Get a fluorine-doped tin oxide (FTO) transparent and conductive coating on your substrates: ceramics, glasses, quartz, or any heat resistant substrate. Inquiries are welcome.

How are transparent conductive oxides used in solar cells?

Instead, it uses a “grid contact”: a network of very thin metal wires. 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 ).

Can a conductor be patterned on a substrate?

The conductor sheet resistance, substrate area, and substrate thickness can be selected in off-the-shelf values or customized as needed, and the conductor can also be patterned by laser or chemical etching with a resolution of +/- 50um.
