METHOD FOR MANUFACTURING SOLAR CELL, SOLAR CELL, AND SOLAR CELL MODULE

원문 (중국어)

The present application discloses a method for manufacturing a solar cell, a solar cell, and a solar cell module. In one example, a method includes: forming an emitter layer on a semiconductor substrate; forming a passivation layer on the emitter layer; forming an insulating layer on the passivation layer; forming busbars on the insulating layer, where the busbars extend in a first direction and are arranged at intervals in a second direction fingers on the insulating layer, where the fingers extend in the second direction and are arranged at intervals in the first direction. The busbars extend toward the emitter layer. A depth of the busbars extending into the passivation layer is no greater than 90% of a thickness of the passivation layer, and a depth of the busbars extending into the insulating layer is greater than 20% of a thickness of the insulating layer.
