Analysis and fabrication of MIS solar cells with majority carrier conduction characteristics Au, Ho Piu

Abstract

A simple model for a MIS solar cell incorporating the effects of inversion layer charge and non-uniform surface state charge has been generated. The inclusion of these terms in the analysis results in theoretical In I-V characteristics which, under forward bias in the dark, have a two slope nature very similar to that of practical MIS solar cells that have been reported to be operating in a minority carrier conduction mode. As the present model considers solely majority carrier conduction, an alternative explanation of the operation of these devices can be proposed. Experimental data were obtained from Al/SiO[sub x]/pSi solar cells and good agreement with the proposed theory was obtained.
