Photochromic glasses with photovoltaic panels


THEphotochromic glassesthey have the particularity of starting a reversible chemical reaction whenever they are exposed to sunlight. Generally solar radiation causes a darkening of theglasses. What happens when aiphotochromic glassesthe technology used in the sector is addedphotovoltaic?

Photochromic glasses, introduction
THEphotochromic glassesthey are quite common, from luxury cars with windshields that darken when exposed to direct sunlight, up to the most commonphotochromic lensesthat transform eyeglasses into sunglasses. When not exposed to UV rays, the lenses and more generally iphotochromic glassesthey turn out to be normal transparent glasses with a minimum percentage of residual color.

Technically, iphotochromic glassesthey can have various colors by combining different substances. It can range from dark gray to brown or green. Some industries have developedphotochromic glassesable to vary the color by proposing shades of indigo or blue but on the market, the most common options are dark gray and brown.

Photochromic photovoltaic glasses, the Italian product Solarglas
THEglassesSolarglas have a double peculiarity, besides beingphotochromicincorporatephotovoltaic panels capable of storing energy directly in the glass. In technical terms:

"THE photochromic glasses their transmission coefficient may vary depending on the intensity of the light that hits them. Due to the action of silver halides (a chemical compound formed by silver combined with fluorine, chlorine, bromine and iodine) contained in them, these glasses take on a gray color when exposed to sunlight. The greatest benefit obtained is the economic savings on costs that were initially incurred for the use of electricity. "These are the words released by the sector experts to our Interview Manager Marta AbbĂ .
