Abstract
We investigated a set of films composed by zinc-phtalocyanine (Zn-Pc) dispersed into a poly-methyl methacrylate (PMMA) matrix, to evaluate the radiative cooling performance through the two infrared transparency windows of IR radiation in the atmosphere. ZnPc present strong and accentuated absorption bands in both visible and infrared range and can dissipate energy by radiating in the infrared band. We will firstly describe the process of samples preparation. Afterwards, we will introduce the experimental setup employed for linear optical characterization in the infrared range along with the obtained experimental results. Finally, we will give details about the numerical model that we developed in order to evaluate the radiative cooling effectiveness of the different films..
