Study the properties of polycrystalline silicon solar cell

Abstract

In the present work, we have studied the properties of polycrystalline silicon solar cell at room temperatures. The structure properties of the polycrystalline silicon solar cell have been studied by XRD spectrum and by using optical microscopy.

   The condition of preparation has been optimized to get good photovoltaic characteristic, these include short circuit current I_SC is equal (13.6mA/Cm²)and open circuit voltage V_OC is( 35 0.4V ) The conversions efficiency η % of the solar cell is equal to( 3.95)and the fill factor  f.f is ( 0.42).
