PROCEDE DE METALLISATION DE CELLULES PHOTOVOLTAIQUES A MULTIPLES RECUITS

摘要

The method involves forming a silver based metallization (110) on a front surface (108) of a photovoltaic cell (100) using serigraphy. The photovoltaic cell is annealed with temperature comprised between 800 and 900 degree Celsius. An aluminum based metallization (112) is formed on a rear surface of a P type polycrystalline silicon based substrate (102) of the cell. The cell is again annealed with the temperature comprised between 800 and 900 degree Celsius. A silicon nitride based and hydrogen rich anti-reflection coating layer (106) is formed on a front surface of the substrate. An independent claim is also included for a method for forming a photovoltaic cell.
