Silicon Dioxide

it is an oxide of silicon with a chemical formula of SiO2. Silicon dioxide is most commonly found in nature as sand or quartz.

Metallurgical Silicon

it is made from silicon dioxide and it is at least 98% pure.

Polysilicon

it is a primary raw material for solar cells and semiconductor devices. Based on the purity, it can be divided into solar grade polysilicon (6N or above) and electronic grade (11N or above)

Modified Siemens Process

it is the main method to produce polysilicon. The modified Siemens process results in higher utilization of TCS, requires less electricity and is also more environmentally friendly as less pollutants are produced than the original Siemens reactor process.

Wafer

it is a thin sheet of semiconductor (photovoltaic) material made by cutting it from a single crystal or polycrystalline ingot.

Solar Cell

a solar cell is fundamentally a semiconductor device which converts light into electrical energy.

Solar Module

it is a number of solar cells electrically connected, protected from environmental stresses, self-contained and not sub-dividable, providing a single electrical output.

BIPV

building integrated photovoltaics system. It consists of integrating photovoltaics modules into building construction materials, such as a roof or a facade. PV modules used in BIPV system can be thin film or crystalline.

FIT

feed-in-tariff. It is an above-market rate set by the government at which the electricity generated from solar photovoltaics is sold. FIT is a popular incentive structure to encourage the adoption of Solar PV systems through government legislation.
