Resumen
Accumulator and converter of solar thermal energy provided with a cylindrical geometry vessel with a phase change material inside and a cylindrical optical cavity at its center, defined by the internal walls of the vessel and an opening. Within said cavity, on the axis thereof, is located a thermal emitter. A thermal insulating cover surrounds the vessel except in two portions, one corresponding to the opening and another corresponding to the position of a thermophotovoltaic converter, where the converter is located on the same axis as the emitter, aligned with the insulating cover. Thus, the power generation capacity increases during the charging phase of the system and, in addition, a greater conversion efficiency is achieved by achieving a uniform temperature profile in the emitter.
