What is a Solar Cell?

A solar cell is the converting mechanism within a solar panel that absorbs sunlight and turns it into electricity. This physical and chemical process is called the photovoltaic effect.

Solar cells are primarily made of pre-stressed glass, aluminium, and monocrystalline silicon. Glass is the outter-most layer of the cell. It’s thermally pre-stressed to increase durability and is equipped with anti-reflection technology. The internal layer is mostly monocrystalline silicon, a semi-conductive material that makes the sunlight to electricity conversion process possible. The cell is backed with a composite film and framed with anodised aluminum for extra strength.

Between 60 and 72 solar cells make up an average sized residential solar panel. Each solar cell produces electricity individually and the panel’s wattage is reflective of the total output of all the cells.
