Abstract

In concentrated solar power systems (CSP), solar receivers need to have high light absorption and high durability at elevated temperatures. In this study, we preset high absorption, high durability coatings for solar receivers in CSP plants. Black pigments and TiO2 porous structure were created to enhance optical properties, while the coating film was formed with 3 layers (base layer, absorption layer and top coating) to enhance durability. It is shown that this coating is stable at 850°C after 100 hours of aging, while keeping a solar-weighted absorptance value of 96-97%. This is higher absorptance and higher durability than conventional coatings used for CSP.
