摘要： A solar cell, comprising: a doped silicon substrate, the silicon substrate comprising a front surface and a rear surface; a front phosphorous diffusion layer formed on the front surface; a front anti-reflective layer formed on the front phosphorous diffusion layer; a front metal electrode on the front surface in ohmic contact with the front phosphorous diffusion layer through the front anti-reflective layer; a rear passivation layer formed on the rear surface; a rear metal electrode in a pattern on the rear surface passing through the rear passivation layer; and a rear p+ diffusion area on the rear surface between the rear passivation layer and a boron-doped region of the silicon substrate, the rear p+ diffusion area surrounding the rear metal electrode.
