Abstract
Process for producing strip-shaped and/or point-shaped electrically conducting contacts on a semiconductor component like a solar cell, includes the steps of applying a moist material forming the contacts in a desired striplike and/or point-like arrangement on at least one exterior surface of the semiconductor component; drying the moist material by heating the semiconductor component to a temperature Tand keeping the semiconductor element at temperature Tover a time t; sintering the dried material by heating the semiconductor component to a temperature Tand keeping the semiconductor component at temperature Tover a time t; cooling the semiconductor component to a temperature Tthat is equal or roughly equal to room temperature, and keeping the semiconductor component at temperature Tover a time T; cooling the semiconductor component to a temperature Twith T≦−35° C. and keeping the semiconductor component at temperature Tover a time T; and heating the semiconductor component to room temperature.
