“…The cavity geometry with an aperture hot mirror coating allows for larger retention of thermal radiation in the receiver [14][15][11] [16]. A triangular cavity receiver has the highest optical efficiency among the non-cylindrical cavity receivers followed by the elliptical cavity with flat plate reflector [17][18] [19].…”

In this paper, we discuss an improved concept of for a cavity receiver unit for Solar Parabolic Trough Collectors (PTC) with the application of hot mirror coating (HMC) on a cavity aperture. This design aims to lessen radiant energy losses while operating at higher temperature by incorporating a variety of optically active layers. We present the theoretical background, which we derived in previous work, and the resulting implementation in a simulation code. We next discuss the layout and results of an experiment, which allowed us to make contact with the simulation with minor adjustments It was seen that the correspondence between the experiment and simulation results was encouragingly close (Chi squared p > 0.8 and p > 0.95), and we proceeded to investigate simulations of different receiver designs. Simulated outcomes for the temperature of the heat transfer fluid, temperature maps and efficiencies are presented. Our proposal indicates temperature related benefits when compared to other popular designs in terms of the heat transfer fluid temperature and the efficiency.
