Currently the solar cells have an efficiency 20%, if the news is true, the efficiency will be 80%!!
efficiency =electricall energy/solar energy
if you have solar energy in 1 square meter=100 Wh with the currently solar cells you have an electricall energy of 20 Wh, with the new solar cells you have 80 Wh. This means that with the same electricall energy, I use a smaller surface than 75%!! It will be beautifull When it will be donne.
