DETAILED DESCRIPTION - The layered system (1) comprises a metal substrate (2) provided with an embossed polymer coating layer (3) for light scattering, a solar cell back electrode (5) following the shape of the polymer coating layer and having a high light reflectivity, photovoltaic active layers (8) that are effectively transform light into electricity, and a transparent top electrode. The embossed polymer coating layer is provided with an adhesion layer such as a chromium oxide layer or an aluminum layer, and provides a holographic effect. The back electrode is a metal layer having a thickness of 0.1-0.6 mu m, where the metal layer is a silver or aluminum layer. The photovoltaic active layer comprises thin films of photovoltaic active silicon, or thin film based on photovoltaic active small organic molecules or polymer or hybrid based donor-acceptor layers system combined with hole conducting and exciton blocking layers. An additional scattering layer is provided on the back electrode, which has a refractive index between the back electrode and the photovoltaic active layer, and is optionally provided with a silicon-oxide nanolayer or hole conducting or exciton blocking layer. The metal substrate is a mild steel strip provided with a corrosion protection coating or a stainless steel or aluminum or aluminum alloy strip. An INDEPENDENT CLAIM is included for a method of producing a layered system for a solar cell.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a layered system.
