Customer ServiceA silicon solar cell is a photovoltaic cell made of silicon semiconductor material. It is the most common type of solar cell available in the market. The silicon solar cells are combined and confined in a solar panel to absorb energy from the sunlight and convert it into electrical energy.
This property of silicon is often used in light-sensitive devices to ascertain the presence of light and calculate its intensity. It also comes in handy to understand the internal mechanisms of these devices. The excellent photoconductivity of silicon makes it an excellent choice for solar cells.

This lattice provides an organized structure that makes conversion of light into electricity more efficient. Solar cells made out of silicon currently provide a combination of high efficiency, low cost, and long lifetime.
All silicon solar cells require extremely pure silicon. The manufacture of pure silicon is both expensive and energy intensive. The traditional method of production required 90 kWh of electricity for each kilogram of silicon. Newer methods have been able to reduce this to 15 kWh/kg.
Single crystalline silicon solar cells are made using the Czochralski process, an energy-consuming process. The purity of the silicon is paramount for the uniform formation of the crystalline structure. This means impurity concentration has to be reduced to 10% or below.
Today, silicon dominates the semiconductor scene, especially in the solar panel market. However, the crystalline form of silicon is harder and more expensive to develop. So, in the effort to bring the cost down, other forms of silicon as well as other semiconductor materials are being utilized in the making of solar cells.
