How do solar panels work?

The solar industry is used to produce solar cells that absorb light on one side. Recent innovations have allowed the increased production of bi-facial modules, allowing light absorption on both sides of the solar module. Passivated Emitter and Rear Contact (PERC) solar cells are also gaining popularity in solar panel production.

How are solar panels made?

From ingots to wafers: Next, the silicon ingots are sliced into thin silicon wafers. These wafers serve as the foundation for solar cells. The most common solar panels and PV modules are made with hexagonal or rectangular cells. The silicon wafer disks are then cleaned and textured to minimize sunlight reflection losses.

How do photovoltaic modules work?

To make electrical connections easier, photovoltaic modules come with a junction box. The direct current (DC) electricity produced by the cells is transformed into alternating current (AC) electricity by an inverter that is fixed to the solar panel. The image below shows the multiple components used in assembling solar modules.

How are solar cells made?

This pure silicon is then melted and formed into either monocrystalline silicon or polycrystalline silicon ingots, thanks to the Czochralski (CZ) process. From ingots to wafers: Next, the silicon ingots are sliced into thin silicon wafers. These wafers serve as the foundation for solar cells.
