Title:
PHOTOVOLTAIC POWER GENERATION-TYPE ROLL BLIND HAVING IMPROVED POWER GENERATION EFFICIENCY
Document Type and Number:
WIPO Patent Application WO/2020/091290
Kind Code:
A1
Abstract:
The present invention relates to a photovoltaic power generation-type roll blind having improved power generation efficiency, the photovoltaic power generation-type roll blind being characterized by comprising: a main body (10) provided with a frame (11) having a length corresponding to at least the width of a window, and a roller (15) rotatably built into the frame (11); a curtain (20) in which transparent sheets (21) through which light passes and power generation sheets (25) that block light and transform the light into electrical energy are consecutively arranged, the curtain (20) being wound on the roller (15) in a state in which one end of the curtain is fixed to the frame (11), and unwound in a double layer; and an adjustment plate (30) which is interposed between the layers of the double layer of the curtain (20) and imparts a spreading load, rolls as the curtain unwinds, and varies the spreading angle of the curtain (20) on the basis of the illuminance of the solar rays. Therefore, the present invention has the effects of: forming a roll-type curtain, which combines the transparent sheets through which light passes and photovoltaic power generation sheets into a double layer, and thereby inducing power generation while allowing a user to adjust an awning as desired; and varying the angle of the power generation sheets according to the illuminance of the solar rays using only a lightweight, thin, short, and small adjustment plate, thus making it possible to minimize production costs while maximizing overall power generation efficiency.
