Abstract

We investigate the correlation of bulk CdTe and CdZnTe material properties with experimental open-circuit voltage ( Voc) through fabrication and characterization of diverse single-crystal solar cells with different dopants. Several distinct crystal types reach Voc > 900 mV. Correlations are in general agreement with Voc limits modeled from bulk minority-carrier lifetime and hole concentration.
