The research results about the single crystalline silicon buried contact solar cells(BCSC)with localized rear contacts are reported in this paper.On the basis of simulation and calculation,proper cell structure was designed.With the optimized processes,the conversion efficiency of 17.28%(VOC=650.4 mV,JSC=33.15 mA/cm2,FF=0.801 4,AM=1.5 G)has been achieved on 4 cm2 solar cell.
