Mapping of Oxygen-Related Defects in Silicon for High Efficiency Solar Cells: Application to the Prediction of LID Losses

Abstract

This study focuses on the mapping of oxygen-related defects in industrial monocrystalline silicon wafers. All mappings were obtained solely from resistivity measurements and specific furnace anneals. An emphasis is given on the boron-oxygen complex responsible for the light-induced degradation (LID) of the carrier lifetime in boron-doped wafers. It is shown that the predicted values for the lifetime limited by the boron-oxygen complexes after complete degradation are in very good agreement with the experimental observations. It is also shown that the present technique is a valuable tool to predict the cell LID from measurements on as-received wafers, which is of paramount interest for wafer/cell manufacturers.
