2. Amorphous silicon - Wikipedia

   en.wikipedia.org/wiki/Amorphous_silicon

   Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs.. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic.

3. Polycrystalline silicon - Wikipedia

   en.wikipedia.org/wiki/Polycrystalline_silicon

   Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process.

4. Low-temperature polycrystalline silicon - Wikipedia

   en.wikipedia.org/wiki/Low-temperature...

   Polycrystalline silicon (p-Si) is a pure and conductive form of the element composed of many crystallites, or grains of highly ordered crystal lattice.In 1984, studies showed that amorphous silicon (a-Si) is an excellent precursor for forming p-Si films with stable structures and low surface roughness. [2]

5. Thin-film transistor - Wikipedia

   en.wikipedia.org/wiki/Thin-film_transistor

   Because it is naturally abundant and well understood, amorphous or polycrystalline silicon were (and still are) used as the semiconductor layer. However, because of the low mobility of amorphous silicon [ 2 ] and the large device-to-device variations found in polycrystalline silicon, [ 3 ] [ 4 ] [ 5 ] other materials have been studied for use ...

6. Thin-film solar cell - Wikipedia

   en.wikipedia.org/wiki/Thin-film_solar_cell

   Thin-film solar cells, a second generation of photovoltaic (PV) solar cells: Top: thin-film silicon laminates being installed onto a roof. Middle: CIGS solar cell on a flexible plastic backing and rigid CdTe panels mounted on a supporting structure Bottom: thin-film laminates on rooftops Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or ...

7. Crystalline silicon - Wikipedia

   en.wikipedia.org/wiki/Crystalline_silicon

   Crystalline silicon or (c-Si) is the crystalline forms of silicon, either polycrystalline silicon (poly-Si, consisting of small crystals), or monocrystalline silicon (mono-Si, a continuous crystal). Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells .
