"It's not clear exactly what the chemical reactions are,
but they lead to the formation of gold nanoparticles that
drill nanoholes at varying depths into the wafer."


Wow! Golden nano-drillers.. Trained to make us very black PV cells.. ;)

This all sounds great. I hope they sell the process to PV makers for a reasonable price.
Since the process seems so inexpensive and it's easy to retrofit a line with
the Golden bath, I can see the new technology giving PV a real boost in the market..

Just hope they do it before I buy a bunch of old-tech panels.. :eek:
