Vienna University of Technology researchers have recently announced the development of the world's thinnest solar cells , the material is able to absorb light, tungsten selenide .
Tungsten selenide layer structure consisting of the elements tungsten, selenium , and two layers sandwiching its molecules . Since the battery is too thin tungsten selenide , 95% of the light can pass through it , which means that there is converted into a 5% than the possibility of power , so the battery efficiency is very high .
The research team believe that this battery can be a lot of coverage in the building surface , the case does not affect the illumination can provide electricity , can be described as perfect.
Although tungsten selenide cells when to put into practical use is unknown , but researchers believe that soon spread.
