Passivation contact solar cell

The invention provides a passivation contact solar cell, which comprises a basal layer, a passivation tunneling layer and a current carrier selecting layer which are stacked sequentially, wherein the current carrier selecting layer comprises a high-work-function metal layer or a low-work-function metal layer; a metal work function of the high-work-function metal layer is larger than or equal to 5eV; a metal work function of the low-work-function metal layer is smaller than or equal to 4eV. According to a current carrier selection passivation contact solar cell, laminated metal layers are prepared from metal materials, and the structure is simple; the current carrier selecting layer metal materials can simply regulate and control work functions, the process for preparing the high-work-function layer or the low-work-function layer is simple, a high-temperature long-time processing process required for preparing phosphorus-doped, nitrogen-doped or boron-doped silicon alloy is not required, the process complexity is reduced, the process window is widened, and a high-temperature processing process required for preparing the silicon alloy and side effects caused by the high-temperature processing process are favorably avoided.
