Abstract

Release of the alkaline (mainly sodium) impurities from the soda-lime glass (SLG) substrate can compromise scaling-up of thin film photovoltaic (PV) devices deposited at high temperatures. This does not only degrade electronic device quality but also results in catastrophic effects such as delaminat...
