Abstract
The n-type region of a silicon solar cell is metallized with a nickel-antimony alloy to provide an external contact.
Claims5
A metallized silicon solar cell having an N-type and a P-type region, prepared by (a) screen printing the N-type region of the solar cell with a thick film composition comprising an alloy of nickel and antimony dispersed in particle form in an organic vehicle in a concentration sufficient to make a printable paste, and (b) firing the printed composition to a temperature within the range of 500-650.degree. C. in an inert atmosphere with a dwell time of about 6 minutes at the peak temperature.
