Abstract

Method for developing a high performance selective surface based on : the chemical attack of the original copper band so that a thin layer of copper sulphate and copper oxides forms on it with selective characteristics; its protection in four different manners.This selective band is produced industrially for use in solar collectors (solar absorbers) of a low cost and features particular strength and selectivity.
