Polycrystalline silicon typically has impurity levels of less than one part per billion.

Polycrystalline silicon is also a key component of solar panel construction.

Polycrystalline silicon photovoltaics - are a type of solar cell.

But the single-crystal is expensive and scientists are making cells of cheaper polycrystalline silicon.

The panels are of polycrystalline silicon photovoltaic technology.

In between the two extremes there is polycrystalline silicon, which is made up of small crystals, known as crystallites.

Polycrystalline silicon, also called polysilicon, is a material consisting of small silicon crystals.

Polycrystalline silicon is sometimes used in displays requiring higher TFT performance.

In other words, a light powered by polycrystalline silicon photovoltaic cells that power the rechargeable nickel cadmium batteries.

Analysts have predicted that prices of polycrystalline silicon will drop as companies build additional polysilicon capacity quicker than the industry's projected demand.

Nanocrystalline silicon and small-grained polycrystalline silicon are considered thin-film silicon.

Polycrystalline silicon is composed of many smaller silicon grains of varied crystallographic orientation.

The silicon film is crystallized by an annealing step, temperatures of 400-600 Celsius, resulting in polycrystalline silicon.

Deal-Grove also fails for polycrystalline silicon ("poly-silicon").

The polycrystalline silicon produced has been chosen by the European Community for the manufacture of high efficiency solar cells in the European project.

The deposition of polycrystalline silicon on plastic substrates is motivated by the desire to be able to manufacture digital displays on flexible screens.

The use of polycrystalline silicon in the production of solar cells requires less material and therefore provides higher profits and increased manufacturing throughput.

This is in contrast to polycrystalline silicon (poly-Si) which consists solely of crystalline silicon grains, separated by grain boundaries.

A new attempt to fuse the advantages of bulk silicon with those of thin-film devices is thin film polycrystalline silicon on glass.

DelSolar's solar module includes monocrystalline and polycrystalline silicon solar modules and black modules.

The structure is then annealed at temperatures between 150 C and 400 C which causes the a-Si films to be transformed into polycrystalline silicon.

Polycrystalline silicon carbide (SiC) is the most commonly used emitter for burner TPVs.

Polycrystalline films are common in semiconductor devices, as the gate electrode of a field-effect transistor is often made of polycrystalline silicon.

Growth rates above 2 micrometres per minute produce polycrystalline silicon, and negative growth rates (etching) may occur if too much hydrogen chloride byproduct is present.
