METHOD FOR TREATING PHOTOVOLTAIC CELLS AGAINST REDUCED EFFICIENCY DURING ILLUMINATION

摘要

The invention relates to a method for treating photovoltaic cells against efficiency loss during illumination, allowing the treatment time to be reduced while improving stability in the "regenerated" state to temperatures above 170°C. For this purpose, the invention relates to a method for treating photovoltaic cells against efficiency loss during illumination, said method comprising the following steps: obtaining a boron-doped silicon substrate containing oxygen dimers in order to form a photovoltaic cell, heating the substrate to a temperature between 300°C and 500°C for a pre-determined treatment time, and directly polarising the photovoltaic cell at a pre-determined potential difference for a pre-determined treatment time.
