Abstract: Receiving and storage of energy, and particularly a particle solar receiver for solar thermal power generation. The particle solar receiver includes: a feeding bin temporarily storing endothermic particles to be heated, and a multi-stage plate heat absorbing channel allowing the particles to flow along a predetermined path by gravity, where the multi-stage plate heat absorbing channel includes a plurality of plate-type structures which forms a changing flow direction of the particles flowing between adjacent plate-type structures. The particle solar receiver can achieve the endothermic particle heating function with a simple structure, i.e., the function of converting the solar power into thermal energy at a high-temperature level.
