Abstract
A good solar thermal panel should have a good selective coating. Black chromium coating bcc is well known to have hgih performance in absorbing high solar radiation and low emittance in solar spectrum near infrared region1. A lot of work has been carrie out 2.3 to determine the deposition and planting parameters that effected the optical properties of the thin black film. This paper described the development of the bcc as an attempt to the thermal energy application. The present optical properties produced high absorption rate 0.966-0.971 and low emittance 0.379 calculated from the reflectance measurement near infrared region. Electroplating method is highlighted to explain the simple and most economical process to produce the black selective surface. The particle size and distribution observed under scanning electron microscope SEM and analysed using energy dispersive X-ray EDX shows that the particles consists of chromium and Cr subscript 2 O subscript 3. The size of the particles is also affected by changes in current density and plating time.
