Abstract

The effort aims to develop a reactor and its peripheral devices and process management technology therefor and to develop chlorosilane hydrogen-reduction process technology as part of the endeavors to develop a low cost production process for silicon for photovoltaic cells for the purpose of building a model plant capable of approximately 10 tons/year in terms of SOG (spin on glass) silicon. A study is made of ten operations (total reaction time of 2,264 hours), and it turns out that the electric power consumption efficiency is near the initially planned value. The yield of Si is, however, but 16.5% which is lower than the initially planned value of 20%. The value is elevated to 18% by raising the reactor temperature. To prevent overcleaning, a reactor with its internal walls experimentally coated with SiC is tested. The problems with devices other than the reactor tube are extraction rendered difficult by anomalously grown granules and processing devices choked by Si powder contained in waste gas after reaction. The first problem is settled by modifying the extraction tube but the other still needs a remedy. The produced granules are found to be high in quality. The seed producing roll crusher is operated for a  More>>
