The inhibition of light-induced degradation of p-type silicon solar cell was hot spot and difficulty in field of photovoltaic technology. The breakthrough in gallium-doped Czochralski silicon technology and the application in crystalline silicon cells solved this problem,successfully suppressing the light-induced degradation. Because of the difference in radius between boron and gallium and different heat treatment conditions in solar cell manufacturing process,it was very necessary to explore the impact of...
