METHOD OF MANUFACTURING PHOTOVOLTAIC DEVICE, SYSTEM OF MANUFACTURING PHOTOVOLTAIC DEVICE, AND PHOTOVOLTAIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a photovoltaic device that improves the operation efficiency of a photovoltaic device to be obtained finally as well as reducing the manufacturing cost and its complexity.

SOLUTION: This invention relates to the method of manufacturing a photovoltaic device. The device comprises: a semiconductor wafer; one or more doped regions formed on the surface of the semiconductor wafer; and a plurality of conductive wires arranged on the surface of the semiconductor wafer and in contact with the one or more doped regions. The method further comprises: a step of forming a full-face passivation layer on the surface of the semiconductor wafer; a step of defining a plurality of openings in the passivation layer using a non-contact patterning apparatus so that each of the openings exposes corresponding one of the one or more regions on the surface of the semiconductor wafer; and a step of mounting the contact part of the conductive wire in each of the plurality of openings using a direct drawing metal wiring apparatus.
