Abstract:
A solar energy converter comprising:a light-concentrating instrument for concentrating sunlight; an electron emitter in an insulated vacuum vessel, emitting electrons in a vacuum as a temperature rises from irradiation of the sunlight concentrated by said light-concentrating instrument; an electron accelerator within said light-concentrating instrument; a cathode on a surface of said electron emitter opposite to a light-irradiated surface which is irradiated by the sunlight, and electrically connected with said electron emitter; an electric field supplier having a positive terminal and a negative terminal; and an electron collector in said vacuum vessel, collecting the emitted electrons flying from said electron emitter toward said electron accelerator, wherein said electron accelerator is connected with the positive terminal of said electric field supplier and said cathode is connected with the negative terminal of said electric field supplier so that an electric field is generated, and said electron collector is used as a negative generator electrode and said cathode is used as a positive generator electrode in which the collected electrons in said electron collector migrate to said electron emitter to generate electricity.
