Abstract: A multi-function solar cooking appliance is disclosed. The appliance comprises a solar thermal unit comprising: at least one solar heat collector for collecting solar heat; a chamber of said solar heat collector for receiving a utensil and thermally connected said solar heat collector to receive and transfer said solar heat to said utensil for cooking; and a sunlight reflector having a cross section with a circular arc shape and said utensil. The appliance further selectively comprises a multi-functional cover, a modular solar thermal unit, assembled fluid channel, supplementary energy heater, different side chambers and/or utensils for heat insulation purpose; disposable utensil and ferromagnetic heat conducting and storage material.

Abstract: This disclosure provides a high efficient space shell solar energy unit. The unit used at least two different solar energy absorbing materials for absorb solar energy from different spectrum of sunlight. The absorbing materials comprising at least one transparent solar energy absorbing material absorbed solar energy mainly from ultraviolet ray and/or infrared ray of sunlight. The unit can be new manufactured or improved from existing low-E glass, PV Panel and thin film cell.
