Abstract

An exemplary portable solar power generator includes a hollow light pervious housing, a light guide element, a condensing lens, a solar cell unit, and a connector assembly. The housing has a first refractive index, and sunlight enters the housing by passing through an outer surface thereof. The light guide element is positioned in and attached to the housing, which has a second refractive index larger than the first refractive index. The condensing lens is positioned in the housing, which is configured for converging the light incident thereon. The solar cell unit is positioned in the light pervious housing and located at a side of the condensing lens opposite to the light guide element. The solar cell unit is configured for receiving the light converged by the condensing lens and converting the received sunlight into electrical energy. The connector assembly is electrically coupled to the solar cell unit.
