Impact of defect type on hydrogen passivation effectiveness in multicrystalline silicon solar cells
2010
2010 35th IEEE Photovoltaic Specialists Conference
In this work we examine the effectiveness of hydrogen passivation at grain boundaries as a function of defect type and microstructure in multicrystalline silicon. We analyze a specially prepared solar cell with alternating mm-wide bare and SiNx-coated stripes using laser beaminduced current (LBIC), electron backscatter diffraction (EBSD), synchrotron-based X-ray fluorescence microscopy (µ-XRF), and defect etching to correlate preand post-hydrogenation recombination activity with grain boundary
