What is it about?
The synthesis and properties of materials for solar energy conversion, especially nanomaterials, have been investigated in order to build solar systems with lower cost and higher efficiency. Carbon-based nanomaterials have been recognized as promising candidates due to their outstanding physicochemical properties. Among them, Metal-containing Diamond-Like Carbon (Me-DLC) coatings have been investigated to enhance absorption of solar radiation and also enhance heat transfer to working fluid in solar collectors.

Why is it important?
The wide use of sunlight for energy generation still faces challenges related to high cost and low efficiency. The successful expansion of the capacity for solar energy production depends on technological advances in several fields, particularly materials science and engineering. The key mechanisms of solar energy conversion are dominated by the intrinsic properties of the active materials that constitute the photovoltaic or solar thermal collector systems.
Perspectives
A high optical selectivity has been achieved for Me-DLC multilayered solar absorber coatings, which become this configuration as an alternative to the commercially available double cermet based coatings.
