The core component of double-glass solar panels is the solar cell,
which is typically made from silicon. Silicon is a semiconductor
material that has properties that allow it to absorb photons (light
particles) and convert them into electrical energy. When sunlight
strikes the surface of a solar cell, it causes electrons within the
silicon material to become excited and move around. This movement
of electrons creates an electrical current, which can then be
harnessed and used to power electrical devices.
“Passivated Emitter and Rear Contact” solar cells, known as PERC
solar cells, are becoming more common today as an option for making
solar panels. PERC solar cells are modified conventional cells that
enable the cells to produce 6 to 12 percent more energy than
conventional solar panels.
