Zusammenfassung:	The present invention relates to an antireflection coating composition for a solar cell, which comprises organic-inorganic modified silicate, a nanosized refraction reducing agent, hydrophobic colloidal silica, and a curing accelerating agent. Different from a conventional multilayer coating having three or four layers, the antireflection coating composition in the present invention is constituted to have a single layer, thereby shortening manufacturing process and reducing manufacturing costs. Also, the antireflection coating composition of the present invention can prevent contamination through self-cleaning by having hydrophobic character and thus can remarkably increase light efficiency. Further, the coating composition of the present invention can secure excellent physical properties such as hardness, adhesion strength, contamination resistance, transparency, etc. In addition, costs of the raw materials constituting the composition is inexpensive and thus the composition of the present invention can be manufactured at one-third of a conventional manufacturing costs, thereby being applicable as an anti-reflection coating for mobile devices, electronic devices, etc. 본 발명은 유-무기 변성 실리케이트, 나노 저굴절화제, 소수성 콜로이달 실리카 및 경화촉진제를 포함하는 태양전지 반사 방지막용 코팅 조성물에 관한 것으로, 기존의 3층 또는 4층 이상의 다층 코팅막과 달리 단층으로 구성되어 제조 공정 및 제조비용을 절감할 수 있으며, 소수성을 가져 자기 세정을 통한 오염 방지로 광 효율을 크게 증가시킬 수 있다는 장점이 있다. 또한 상기 특성 이외에도 경도, 밀착성, 내오염성, 투명성 등에서 우수한 물성을 확보할 수 있으며, 조성물을 구성하는 원료의 값이 저렵하여 기존 원료 대비 1/3의 가격으로 제조할 있어 모바일기기, 전자제품 등의 반사방지막으로도 활용할 수 있다.
