Abstract:
A point-contact solar cell structure includes a semiconductor substrate, a front electrode, a first passivation layer, a second passivation layer, and a rear electrode. The semiconductor substrate includes an upper surface, a lower surface, and an emitter layer, a base layer, and a plurality of locally doped regions located between the upper surface and the lower surface. The plurality of locally doped regions is located on the lower surface at intervals. The second passivation layer is located on the lower surface, and has a plurality of openings disposed respectively corresponding to the locally doped regions. The rear electrode is located on one side of the second passivation layer opposite to the semiconductor substrate, and passes through the second passivation layer via the openings to contact the locally doped regions. The width of at least one opening corresponding to the front electrode is greater than that of the remaining openings.
