Abstract
An improvement in a fine geometry solar cell having a top surface contact comprising substantially more and finer metallic fingers spaced close together for collecting photo current is disclosed. The improvement comprises a reduction in the ohmic contact area of the fine metallic fingers with the light-incident surface of the solar cell. The improved solar cell is constructed by etching a fine line pattern into the anti-reflective coating of the solar cell and then depositing a fine line electrode onto the surface of the solar cell but oriented perpendicular to the etched fine line pattern in the anti-reflective coating. Due to the 90.degree. rotation between the etched fine line pattern in the anti-reflective coating and the fine line electrode, only point contacts are made between the fine line electrode and the exposed light-incident surface of the solar cell.
