摘要:
A transparent front electrode for a photovoltaic device comprising at least the following layers in sequence: -a glass substrate; -a lower anti-reflection layer, comprising in sequence from the glass substrate *a base layer of an (oxi)nitride of silicon and/or an (oxi)nitride of aluminium, *a middle layer of an oxide of Zn and Sn, *a top layer of an oxide of Zn; -a silver-based functional layer; and -an upper anti-reflection layer comprising in sequence from the silver-based functional layer *a first barrier layer of an oxide of Ni and Cr, *a second barrier layer of an Al-doped oxide of Zn,and *a buffer layer; wherein the first barrier layer of an oxide of Ni and Cris located directly in contact with the silver-based functional layer or the first barrier layer of an oxide of Ni and Cr is separated from the silver-based functional layer by one or more additional barrier layers.
