Claim:
1. A method of forming screens for printing electrodes onto a solar cell, comprising: electroforming a first metal screen defining (a) first apertures oriented along a widthwise dimension of the first metal screen and configured to accept a first conductive paste to print finger electrodes onto the solar cell, and (b) at each of the first apertures one or more first support bars crossing the first aperture in a lengthwise dimension of the first metal screen; and electroforming a second metal screen defining one or more second apertures configured to accept a second conductive paste to print one or more buss bars onto the solar cell such that the buss bars cover gaps between the finger electrodes caused by the first support bars.
