In this study, the impact of wafer thickness on the optical and electrical properties of c-Si solar cells is characterized systematically in a wide range of wafer thicknesses from 400 down to 30 µm, with particular interest in SHJ solar cells. 2. Experimental methods
To our knowledge, it is the first experimental demonstration of the dependence of SHJ solar cell performance on wafer thickness in the 60–130 μm range. We demonstrate that the gettering process continues to be beneficial for achieving solar cell efficiency above 26%.
