Zusammenfassung:	The present invention relates to a roll blind photovoltaic power generation system, in which a thin-film solar cell that may be flexibly bent in a form of a roll is provided. In the photovoltaic power generation system according to the present invention, a roll blind (100) blocking sun light through winding and unwinding of a light shielding film (110) includes: a thin-film solar cell (120) arranged on the light shielding film (110) and flexibly formed to be wound together with the light shielding film (110); a storage battery (130) connected to the thin-film solar cell (120) to store electric energy obtained by the thin-film solar cell (120); and a control unit (140) connected to the thin-film solar cell (120) and the storage battery (130) between the thin-film solar cell (120) and the storage battery (130), wherein the control unit (140) has an overcharge preventing circuit (142) configured to control a current value such that the storage battery (130) is not overcharged. In the present invention, the electric energy stored in the storage battery may be efficiently maintained through manually or automatically operating the blind depending on an amount of electric energy stored in the storage battery. 본 발명은 롤 형태로 플렉서블하게 접힘 가능한 박막 태양전지가 구비되어 있는 롤 블라인드 태양광 발전시스템에 관한 것이다. 본 발명에 따른 롤 블라인드 태양광 발전시스템은, 차광막(110)의 권취 및 권출을 통하여 태양빛을 차단하는 롤 형태의 블라인드(100)에 있어서, 상기 차광막(110)상에 배치되어 차광막(110)과 같이 권취되도록 플렉서블하게 이루어진 박막 태양전지(120)와; 상기 박막 태양전지(120)와 연결되어 상기 박막 태양전지(120)로부터 얻어진 전기에너지를 저장하는 축전지(130)와; 상기 박막 태양전지(120)와 상기 축전지(130) 사이에 연결되어 있는 제어부(140):를 포함하며, 상기 제어부(140)는 상기 축전지(130)가 과충전되지 않도록 전류값을 제어하는 과충전 방지회로(142)가 구비되는 것을 특징으로 한다.
