摘 要：The development of new concepts for silicon solar cells has shown promising results in recent *** wrap-through（EWT） solar cells are looked upon as one possible candidate for future next generation crystalline silicon solar *** has the advantage of zero shadow losses,easier module interconnection with both contacts on the back and improved collection efficiency by the backside *** knowledge of the loss mechanisms in EWT silicon solar cells and their dependence on geometrical and substrate parameters provides the opportunity to further increase the cell *** this paper we present the results of the two-dimensional（2D） computer simulations of the EWT cell structure with industrially relevant *** influences of the different loss mechanisms（e.g.,intrinsic losses,optical losses,series resistance losses and recombination losses） on the cell parameters（e.g.,surface recombination velocities,thickness,bulk resistivity,bulk lifetime,cell geometry,etc.） were *** modeling data show that the optimum cell geometry defines a balance between the electrical behavior of the EWT cell and the different losses.
