OPTIMIZATION OF PASSIVATION PROCESS ON THE SILICON WAFER SURFACE DURING FORMATION HETEROSTRUCTURE SILICON SOLAR CELL
Results of formation of heterostructure solar cells on crystalline silicon by deposition on the wafer surface of amorphous hydrogenated silicon are presented in the paper. The procedure of heterostructure formation and crystalline silicon surface defect passivation is described. It is shown that it is possible to achieve minority carrier lifetime over 1 msec after surface passivation, which is sufficient to form heterostructure silicon solar cell with efficiency over 20 %.
