Title (EN) PROCESS AND APPARATUS FOR PRODUCTION OF MONOCRYSTALLINE AND MACROCRYSTALLINE LAYERS, BY EXAMPLE FOR PHOTOVOLTAIC CELLS
(FR) PROCEDE ET APPAREIL POUR LA PRODUCTION DE COUCHES MONOCRISTALLINES ET MACROCRISTALLINES, PAR EXEMPLE POUR DES CELLULES PHOTOVOLTAIQUES
Abstract: front page image
(EN)Production of macrocrystalline and monocrystalline layers. It includes irradiating a polycrystalline layer by sweeping the surface of said layer with a beam focused along a line having a constant power density. Layer material melts in all its thickness but is not vaporised at its outer surface. Material solidifies by forming macrocrystals or, if a seed is provided, a monocrystal. The process is useful for photovoltaic cells.
(FR)Production de couches monocristallines et macrocristallines. La présente invention comporte l"irradiation d"une couche polycristalline en balayant la surface de ladite couche au moyen d"un faisceau focalisé le long d"une ligne possédant une densité de puissance constante. La couche de matériau fond sur toute son épaisseur mais n"est pas vaporisée sur sa surface extérieure. Le matériau se solidifie en formant des macrocristaux ou, si l"on ajoute un germe de cristal, un monocristal. Ce procédé est utile pour des cellules photovoltaïques.
