Abstract :
The existence of slip dislocated material in Czochralski silicon ingots and the effects of the dislocations on solar cell performance have previously been identified. In this paper, cell performance as a function of dislocation density and the distribution of dislocations across a wafer has been characterized in order to quantify the performance losses associated with dislocated material. In addition, improvements in wafer and cell processing have decreased the impact that dislocated materials have on solar cell performance
