  • Method of preparing solar cell front contacts
    Patent number: 5726065
    Abstract: Method of preparing on a solar cell the top contact pattern which consists of a set of parallel narrow finger lines and wide collector lines deposited essentially at right angles to the finger lines on the semiconductor substrate, characterized in that it comprises at least the following steps:(a) screen printing and drying the set of contact finger lines;(b) printing and drying the wide collector lines on the top of the set of finger lines in a subsequent step;(c) firing both finger lines and collector lines in a single final step in order to form an ohmic contact between the finger lines and the semiconductor substrate and between the finger lines and the wide collector lines.
    Type: Grant
