摘要
The present invention relates to a sunlight-thermal energy conversion device capable of converting sunlight into thermal energy. More specifically, provided are a highly-efficient sunlight-thermal energy conversion device having a fine surface structure capable of significantly improving efficiency of sunlight -thermal energy conversion by maximizing absorption ratio of sunlight and accordingly maximizing boiling heat transfer efficiency to other heating media and a manufacturing method thereof. To that end, according to the present invention, the sunlight-thermal energy conversion device includes: a substrate which is made of semiconductor material; a plurality of first nano-wires which are extended upward in the vertical direction to the substrate, are arranged on the top surface of the substrate, and are made of semiconductor material; and a plurality of second nano-wires which are extended downward facing the first nano-wires, are arranged on the bottom surface of the substrate, and are made of semiconductor material. On the bottom surface of the space between the first nano-wires and the second nano-wires, metal particles are distributed in clusters.
