TEMPORARY FIELD ASSISTED PASSIVATION FOR TESTING OF PARTIALLY PROCESSED PHOTOVOLTAIC SOLAR CELLS

摘要

A method for electrical testing of a back contact solar cell applies a first side of a temporary passivation sheet to a frontside of a back contact solar cell, the first side of the temporary passivation sheet comprising at least a transparent dielectric layer. The temporary passivation sheet having a second side opposite the first side and comprising at least a transparent conductive coating. A voltage is applied between the transparent conductive coating and base metallization of the back contact solar cell. The frontside of the back contact solar cell is illuminated through the transparent conductive coating and the transparent dielectric layer. Electrical testing is performed on the back contact solar cell. The temporary passivation sheet is removed from the frontside of the back contact solar cell.
