Investigation of high efficiency silicon MINP solar cells

This paper includes results of both theoretical and experimental studies of silicon metal insulator n/p cells. Performance calculations are described which give expected efficiencies as a function of base resistivity. Fabrication and characterization of cells are discussed, and detailed analyses of current loss mechanisms are presented. Using 0.2-ohm cm FZ material and Mg tunneling contacts, AM 1 efficiencies in the range of 16.5-17 percent have been achieved.
