Synthesis and Characterization of Nanocrystalline Porous Silicon Layer for Solar Cells Applications

  title={Synthesis and Characterization of Nanocrystalline Porous Silicon Layer for Solar Cells Applications},
  author={Raghvendra Sarvjeet Dubey and D. K. Gautam},
In this paper, the nanocrystalline porous silicon layer is prepared by electrochemical etching of p-type silicon wafer. The atomic force microscopy investigation shows the surface roughness and pyramid like hillocks surface on entire surface which can be regarded as a condensation point to form small skeleton clusters which plays an important role for the strong visible luminescence. The room temperature photoluminescence (PL) peak corresponding to blue emission is observed at 567nm which is… CONTINUE READING
