Forming high-efficiency silicon solar cells using density-graded anti-reflection surfaces |
abstract |
A method ( 50 ) is provided for processing a graded-density AR silicon surface ( 14 ) to provide effective surface passivation. The method ( 50 ) includes positioning a substrate or wafer ( 12 ) with a silicon surface ( 14 ) in a reaction or processing chamber ( 42 ). The silicon surface ( 14 ) has been processed ( 52 ) to be an AR surface with a density gradient or region of black silicon. The method ( 50 ) continues with heating ( 54 ) the chamber ( 42 ) to a high temperature for both doping and surface passivation. The method ( 50 ) includes forming ( 58 ), with a dopant-containing precursor in contact with the silicon surface ( 14 ) of the substrate ( 12 ), an emitter junction ( 16 ) proximate to the silicon surface ( 14 ) by doping the substrate ( 12 ). The method ( 50 ) further includes, while the chamber is maintained at the high or raised temperature, forming ( 62 ) a passivation layer ( 19 ) on the graded-density silicon anti-reflection surface ( 14 ). |
