RÉSUMÉ

The optical efficiency of conventional trapezoidal cavity receiver with different aperture radii is analyzed by the Monte Carlo ray tracing (MCRT) method. During fabrication, the bottom surface of the conventional cavity receiver cannot be fully covered by a coiled copper tube which would induce a dead space of solar energy absorption. A proposal for a shape layout of the trapezoidal cavity receiver, i.e., an inverted trapezoidal receiver with a bottom surface interior convex (ITBSIC receiver) is put forward with the objective of solving the problem of dead space absorption and improving the optical efficiency of the conventional trapezoidal cavity receiver. The effects of the interior convex dimensionless height, wall absorptivity, alignment error, and the pointing error on variation of the optical efficiency are analyzed.
