What is Hanwha Q Cells solar panels’ Q.ANTUM technology?
Often referred to as just Q CELLS, Hanwha solar panels are made with Q.ANTUM technology, based on Passivated Emitter Rear Cell (PERC) technology. PERC allows for passivation of the solar cells' rear sides, meaning that sunlight is captured back into the cell rather than it going unused. This means more energy is produced!
With Q.ANTUM solar cells the back surface of the solar cells treated with a nano-coating that functions similarly to a regular mirror. Rays of sunlight that would otherwise go to waste are reflected back through the cell to generate more electricity. In addition, laser-fired contacts enhance the module's electrical properties, increasing their efficiency.
Hanwha Q.ANTUM vs PERC — What’s the Difference?
Q.ANTUM solar cell use PERC technology, along with other features. PERC is just one component within Q Cells. Here’s a list of some of the other features that Hanwha boasts as making up their Q.ANTUM:
Anti LID: LID is higher when there’s a higher concentration of oxygen in the silicon wafers; this causes a reduction in power by 3%. Q.ANTUM‘s Anti LID Technology permanently deactivates Boron-Oxygen complexes in the factory, thus ensuring minimal LID in Q.ANTUM mono cells and avoiding energy losses.
Anti PID: PID (Potential Induced Degradation) comes from a difference in electric potential between the solar cells and the frame of the module. PID can reduce module performance by 80%. Anti PID Technology is set on all Q CELLS products to ensure panels produce energy in any environment.
Hot-Spot Protect: Hot-Spots can lead to delamination and power degradation over time as the backsheet begins to degrade in high temperature. In the worst case scenario, a module can catch fire. Hanwha Q CELLS uses an IR camera to test every cell for potential Hot-Spots. Spatial resolution of the IR camera allows for removal of 100% of affected cells during production.
Tra.QTM: Traceable Quality (Tra.QTM) is a unique laser engraved matrix barcode that every Q Cell receives, so it is possible to trace back every cell from production to your specific panel.
