Solar Cell Silicon Substrate

Crystalline silicon is the crystalline forms of silicon either polycrystalline silicon or monocrystalline silicon.

Solar cell silicon substrate.

Industrial solar cells are fabricated in large volumes mainly on large area 100 cm 2 czochralski monocrystalline or multicrystalline silicon substrates. Individual solar cell devices are often the. In electronics a wafer also called a slice or substrate is a thin slice of semiconductor such as a crystalline silicon c si used for the fabrication of integrated circuits and in photovoltaics to manufacture solar cells. Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells.

In this forum i wish to discuss the effect of the substrate parameters on the performance of solar cells the parameters of. In electronics crystalline silicon is typically the monocrystalline form of silicon and is used for producing microchips. Silicon substrates used in commercial solar cell processes contain a near surface saw damaged layer which has to be removed at the beginning of the process. This is the generalized method used based on a number of sources.

Thin film solar cells are commercially used in several technologies including cadmium telluride copper indium gallium diselenide and amorphous thin film silicon. The process of manufacturing solar cells from single crystal p type silicon wafers is detailed below. It should be noted that different companies have different patented and trade secret processes for each of these steps but the steps remain the same. Thickness of the damage depends on the technique used in wafering of the ingot.

Film thickness varies from a few nanometers to tens of micrometers much thinner than thin film s rival technology the conventional first. A thin film solar cell is a second generation solar cell that is made by depositing one or more thin layers or thin film of photovoltaic material on a substrate such as glass plastic or metal. The silicon solar cell is composed of a p substrate and an n emitter. A solar cell or photovoltaic cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect which is a physical and chemical phenomenon.

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. The wafer serves as the substrate for microelectronic devices built in and upon the wafer.
