<p>The invention relates to a method for treating a silicon substrate for the production of photovoltaic cells against reduction in yield during the illumination of said photovoltaic cells. The invention also relates to a method for producing photovoltaic cells from the treated substrate. To said end, the invention relates to a method for treating a silicon substrate for the production of photovoltaic cells, said method including the following steps: a) providing a silicon substrate obtained from a metallurgically purified load, and b) annealing said substrate by heating the substrate to a temperature between 880° C. and 930° C. for a duration of between one and four hours, preferably at a temperature of 900° C., give or take 10° C., for two hours, give or take 10 minutes.</p> |
