“…Namely, the slag refining method was used for purification. The Institute of Physics and Technology (Almaty, Kazakhstan) has conducted several studies on methods of metallurgical-grade silicon (MG-Si) production and purification of silicon to UMG-Si, as well as research on silane production methods [16][17][18][19][20][21][22]. As a result of previously conducted studies and works, purified silicon samples and Si crystals grown by the Czochralski method were obtained on a laboratory scale, approximately 2-3 kg.…”

This silicon purification research work has two stages and results will be provided in two articles due to the large scope of work. This paper provides the results of the first stage, concerning the metallurgical silicon purification. Silicon was purified by a combined method consisting of slag refining with new slag composition and acid leaching. In the first phase, the metallurgical grade silicon produced by the classical carbothermic reduction method was investigated. In the second phase, the metallurgical purification by slag refining was completed using slags of various new compositions. The purified silicon samples obtained after the melting processes were analyzed for concentrations of impurities. Finally, acid leaching treatment of the obtained silicon was done, followed by elemental analysis of purified silicon. According to our experience we can determine that obtained silicon purity is adequate for further stages of planned study.

This study is devoted to comprehensive study of the physical and electrical properties of solar cells manufactured on the basis of the Kazakhstan multicrystalline silicon of solar grade (SoG-Si). The study applied: 4-point resistance measurement method, a method of microwave detected photoconductive decay (μ-PCD), a method of Light Beam Induced Current (LBIC), methods for spectrometric analysis of reflection, transmission and photoluminescence coefficients, scanning electron microscopy, and methods for analyzing current-voltage characteristics. The batches of Al-BSF and PERC photovoltaic converters based on Kazakhstani silicon were manufactured and analyzed. To improve efficiency, the study proposes a modification of a standard Al-BSF production line to a PERC line using PECVD.
