Abstract
A backsheet stack for a photovoltaic module is disclosed. The photovoltaic module includes a laminate with embedded solar cells. The backsheet stack includes: an outer protective layer, an inner adhesion layer, at least one barrier layer, and at least one reinforcing layer. The outer protective layer is configured to provide protection from ultra-violet radiation. The inner adhesion layer is configured to provide adhesion to a laminate with embedded solar cells. The at least one barrier layer is formed between the outer protective layer and the inner adhesion layer and forms a sealing layer to moisture penetration. The at least one reinforcement layer is formed between the outer protective layer and the inner adhesion layer and provides mechanical stability for the backsheet stack.
