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.
