WHY CAN PHOTOVOLTAIC GLASS CONVERT SUNLIGHT INTO ELECTRICITY?--MAC Glass unveils the first door of the solar panel

Every time I pass by those sparkling solar panels on the roof, I can't help but think: how can we turn sunlight into electricity when it looks like just a few pieces of glass? Later I found out that the key was on that seemingly ordinary photovoltaic glass.

This is not the ordinary glass used for your windows. Photovoltaic glass is more like a "sunshine catcher". It needs to complete three important tasks: first, let the sunshine pass through unimpeded, second, protect the precious power generation chip inside, and finally, withstand the test of hail and rainstorm. The transmittance of ordinary glass is about 91%, while photovoltaic glass can reach over 94% - don't underestimate this 3% difference, which is equivalent to capturing half an hour of sunlight every day!

When I visited the photovoltaic glass factory, the engineer showed me two pieces of glass: "The left side is ordinary glass, and the right side is our product." At first glance, it looked exactly the same. But when he turned on the ultraviolet flashlight, something magical happened - ordinary glass blocks ultraviolet rays outside, while photovoltaic glass allows ultraviolet rays to pass smoothly. These ultraviolet rays are also energy, they cannot be wasted, "the engineer said with a smile.

What surprised me the most was the "invisibility cloak" on the glass surface. Under a microscope, the surface of the glass is covered with pyramid patterns that are smaller than a human hair. These patterns can make sunlight "bend" and reduce reflection loss, just like building a highway for light. Factory teacher Fu said this is called "anti reflection technology", and the inspiration actually comes from the surface of lotus leaves - nature has already written the best design on lotus leaves.

Last year when the photovoltaic power station was installed in my hometown, I specifically touched those glass panels. The surface is warm and cozy, but the position of the battery cells underneath maintains a suitable working temperature. The installer told me that this is because the glass is mixed with special materials, which are both transparent and heat dissipating, just like installing "smart air conditioning" on solar panels.

Now every time I see sunlight shining on the solar panel, I can imagine countless photons passing through this special layer of glass, giving energy to the solar cells like obedient little elves. And this piece of glass, which we are accustomed to, is silently completing a relay race of solar energy that has lasted for billions of years - transforming the energy of ancient stars into electricity that lights up our lives.
