the lowering of the phosphorus dopant density in the emitter of Si solar cells is a current topic in the photovoltaic industry. In lowly-doped emitters, diffusion inhomogeneities between the tops of the pyramids and the valleys affect the saturation current density J0. We quantify diffusion inhomogeneities by means of 3D process simulations, and we evaluate J0 by means of 3D device simulations. Finally,...
We present a study about loss analysis in both-sides-contacted silicon solar cells from a porous silicon (PSI) layer transfer process. Experimental results achieved by a variation of the rear-side contact geometry are characterized by different techniques such as electroluminescence and quantum efficiency measurements and reproduced by 3-D simulations using Sentaurus Device. Since such a device simulation...
