Abstract: front page image
(EN)The present invention relates to a method for preparing a silicon compound from rice hulls or rice straw, and to a method in which rice hulls or rice straw is milled, treated with an acid, and mixed with a reducing agent, and a reFig. 1 AA Rice hulls, rice straw BB Pretreatment step CC Reducing agent (alkali metal) mixing DD Reduction step EE Polycrystal Si FF Inert gas duction reaction is performed on the resultant material in an inert atmosphere, to thereby obtain a silicon compound. The above-described method produces a high purity silicon compound from rice hulls or rice straw through a simple process, and enables the preparation of various silicon compounds by adding raw material gases. The thus-prepared silicon compound can be employed in solar cells.
(FR)La présente invention concerne, un procédé d'élaboration d'un composé de silicium à partir de balle de riz ou de paille de riz, et plus particulièrement un procédé consistant à prendre la balle ou la paille de riz, à la broyer, à la traiter avec un acide, à la mélanger à un agent réducteur, et à la soumettre la matière obtenue à une réaction de réduction sous atmosphère inerte de façon à obtenir un composé de silicium. Le procédé de l'invention, qui permet d'obtenir par un traitement simple un composé de silicium de grande pureté à partir de balle ou de paille de riz, permet notamment d'élaborer divers composés de silicium par adjonction de matières brutes gazeuses. Le composé de silice élaboré selon ce procédé convient à la réalisation de cellules photovoltaïques.
(KO)본 발명은 왕겨 또는 볏짚으로부터 제조되는 실리콘 화합물의 제조방법에 관한 것으로, 왕겨 또는 볏짚을 밀링 후 산처리하고, 이를 환원제와 혼합한 후, 불활성 분위기 하에서 환원 반응을 통해 실리콘 화합물을 제조하는 방법에 관한 것이다. 상기 방법은 왕겨나 볏짚으로부터 간단한 공정을 통해 고순도의 실리콘 화합물을 얻을 수 있고, 다른 원료 가스의 추가 도입으로 인해 다양한 실리콘 화합물의 제조가 가능하다. 이렇게 제조된 실리콘 화합물은 태양전지에 적용된다.
