Description

This conference paper describes the Czochralski (CZ) and float-zone (FZ) crystals were grown from experimental solar-grade silicon (SOG-Si) feedstock materials developed by Crystal Systems. The materials were metallurgical-grade Si and highly boron-doped p-type electronic-grade Si (EG-Si) reject material, both of which were gaseous melt-treated to remove boron. Crystal growth observations, lifetime and impurity characterization of the grown crystals, and device performance of wafers from them are presented. Devices made directly on treated high-B EG-Si feedstock have a little over half the efficiency of devices made from control CZ samples. However, devices on CZ and FZ crystals grown from the treated ... continued below

Devices made directly on treated high-B EG-Si feedstock have a little over half the efficiency of devices made from control CZ samples. However, devices on CZ and FZ crystals grown from the treated high-B EG-Si feedstock have comparable PV performance (14.0% and 13.8% efficiency, respectively) to that of CZ control samples (14.1%).
