The present invention discloses an external particle heat absorber and solar power generation system. The system comprises a heat absorbing portion, the sun-facing end of which absorbs solar energy, and a particle heat exchanger disposed on the shady side of the heat absorbing portion. A heat pipe is also provided, with the evaporation end in heat transfer contact with the heat absorbing portion, and the condensation end in heat transfer contact with particles within the particle heat exchanger. A liquid phase-change medium within the evaporation end absorbs heat from the heat absorbing portion and evaporates into a gaseous phase-change medium. The phase-change medium then enters the condensation end, exchanges heat with cold particles within the particle heat exchanger, condenses into a liquid phase-change medium, and flows back to the evaporation end. The heated hot particles can then be output to the next external device through the output end of the particle heat exchanger. The heat absorbing portion absorbs solar energy, and the phase-change medium within the heat pipe serves as an intermediate heat exchange medium. After evaporation, the phase-change medium transfers heat to the particles, raising the particles to the desired temperature. This system exhibits high efficiency and addresses the low heat absorption efficiency of existing particle heat absorbers.
