Abstract: The invention relates to a method of manufacturing an outside decorative trim strip of a motor vehicle, such as window surrounds or body shell trim, made of aluminum alloy, by shaping and brightening of a plate or strip made by vertical continuous casting of an alloy slab of series AA5xxx of high purity, homogenization-heating of the slab, hot rolling, cooling, cold rolling with intermediate annealing in a continuous tunnel furnace, or holding between the solvus temperature and the alloy burning temperature typically for 3 seconds to 5 minutes, quenching in air or water, possible annealing at a temperature of 100 to 200° C. The invention also relates to a decorative trim strip of motor vehicle manufactured using such a method.

Abstract: The invention relates to a substrate (10) having a metal film (12) for producing photovolatic cells (30), wherein a first side of the metal film (12) is intended for arranging a photovoltaic absorber layer (18). In order to improve the chemical resistance and the corrosion resistance at elevated temperature, a protective layer (16) made of a silicon-based sol-gel paint is arranged on the second side of the metal film (12).
