commercial PV module I can buy right now from SunPower is about 20%
efficient, and I think the highest recorded laboratory efficiency is
only 34% or so, I am immediatly
Disposable solar panels developed using nanotechnology
Scientists at the University of Cape Town are exploiting
the nano-scale properties of silicon to develop a
super-thin disposable solar panel poster which they
hope could offer rural dwellers a cheap, alternative
source of power. Many
