New Generation Silicon Solar Cells

5.5 Solar cell contacts

New Generation Silicon Solar Cells

Advantages:

Simplifies thin film manufacturing process

Efficiency values about 20%

Combination with doted contacts:

Screen printed interface layer (little holes) good passivation

Aluminium on the interface layer COSIMA

Advantages:

Can be used on thinner wafers no bending

The passivation abbility of the amorphous layer will be kept after the annealing process

The contact resistivity is 15mΩcm2

Increase of the  quantum yield in the infrared  wavelength range

Reduces Seff to 100 cm/s (4% metallization)
