polysilicon

Aluminium was once used but now the material is polysilicon.

These are ordinarily made from a particular form of silicon called polysilicon.

In late 2010, booming installation brought up the spot prices of polysilicon.

China is a large producer of polysilicon, for use in first generation solar cells around the world.

The emitter window is opened, followed by the polysilicon deposition.

Finally the hole is filled with conducting polysilicon (red) which forms the channel.

Are you sure you're not talking about polysilicon?

It also sells a significant portion of polysilicon on a spot pricing basis.

Only twelve factories were known to produce solar-grade polysilicon in 2008.

This however changed and, in 2011, there was a large excess of production capacity of polysilicon.

The polysilicon manufacturing market is growing very fast.

Polysilicon is also attractive for the easy manufacturing of self-aligned gates.

During the 1990s, polysilicon cells became increasingly popular.

Even with the advances by Toshiba and others, there is a limit to how big polysilicon displays can be.

When polysilicon and a-Si devices are used in the same process this is called hybrid processing.

While in booming installation times, price rally occurs in polysilicon.

Buyers will accept down payment and long term agreements to acquire a large enough volume of polysilicon.

Its current facilities produce some 36,000 tons of polysilicon, ranking it among the top 5 producers worldwide.

A layer of photoresist is applied on top of the polysilicon.

Nevertheless, there are several reasons favoring use of polysilicon:

Silicidation of source and drain regions and the polysilicon region.

Growth of the photovoltaic solar industry was limited by the supply of the polysilicon material.

The polysilicon monohalides are all stable to 400 C, but are also water and air sensitive.

The alternating layers of conductive polysilicon function as the control gates in this structure.

Connections between metal and polysilicon or diffusion are made through contacts (illustrated as black squares).
