Determination of Gallium Concentration in Silicon from Low‐Temperature Photoluminescence Analysis
Solar RRL, Volume 8, Issue 4, February 2024.A simple method for determining the gallium concentration in silicon for solar photovoltaic applications is presented. It relies on the intensity ratio for bound exciton to the free exciton peaks from photoluminescence measurements at 10 K. The empirical relation describing the calibration curve is deduced, and the effect of temperature and power on ...
