摘要：
The invention provides a process for treating an n-type photovoltaic cell free from all but trace amounts of boron atoms, said process comprising the following steps: providing an n-type heterojunction photovoltaic cell (10) comprising a central crystalline silicon layer (1) on and under which two passivation layers (2, 3) made of hydrogenated amorphous silicon are deposited; heating this cell to a temperature between 20
o C and 200
o C, for example on a hot plate (20) or in an oven (40), while illuminating the photovoltaic cell with a light flux from a light source (30). The efficiency of the photovoltaic cell is thus improved and stabilized.
