RESUMO
We present a method of construction and analysis of relevant radiative properties of electroplated "black nickel" selective surfaces, utilized for phototermic conversion of solar energy. We made 109 surfaces in a controlled system of electroplating. The spectral refletance was obtained by espectrophotometry; and samples appeared to be optically reproducible. It was also analised the behaviour of the total directional absortance, total hemisferical emitance and of the figure of merit, as a function of the elettroplating parameters. The best of all surfaces presented 82% for the total directional absortance and 7,5% for total hemisferical emitance.
