According to physicists of the St. Petersburg University ITMO, their development is another word in solar energy . The luminescent glasses created by them have an unusual property – under the influence of ultraviolet radiation they start to glow with white light.
As is known, under the influence of dust and ultraviolet rays, the efficiency of silicon solar cells is significantly reduced. To avoid this, you must install special protective glass screens.
If they are made of luminescent glass developed by St. Petersburg physicists, then the ability to glow will add to the protective properties. This means that the silicon batteries covered with such a glass will receive an additional portion of light.
For glass to acquire the ability to emit light, silver ions were added to it. The process looks like this: in the temperatures brought to 310 ° C, the silver salts lower the glass. As a result, sodium ions are replaced by silver ions. This technology is used to produce ultra-strong glasses Gorilla Glass .
Among the promising areas of using a unique development – the production of LEDs with a double life.
