Abstract: The present disclosure relates to the technical field of solar cells, and relates to a crystalline silicon solar cell and a preparation method thereof, and a photovoltaic assembly. The crystalline silicon solar cell includes a crystalline silicon substrate, a passivation layer that is disposed on the crystalline silicon substrate and that is provided with through holes, a carrier collection layer that is disposed on the passivation layer, and electrodes that contact the carrier collection layer; the carrier collection layer contacts the crystalline silicon substrate by means of the through holes on the passivation layer. In the described crystalline silicon solar cell, through holes are provided on the passivation layer, and the carrier collection layer contacts the crystalline silicon substrate by means of the through holes on the passivation layer.
