Tl impurity's
WebWhile the incorporation of Tl impurity level alone provides a PCE of 33.4%, with J SC = 51.56 mA/cm 2, V OC = 0.789 V and FF = 82.03%, respectively. The PCE of the solar cell further enhances to 35.4% with an elevation of the short circuit current by 3.76 mA/cm 2 due to the inclusion of Zn impurity into the optimized structure.

WebTl is known to be a valence-skipping element that, ow-ing to the relative instability of a half- lled 6s orbital, has a strong tendency to disproportionate into Tl+ and Tl3+ rather than accommodate a 2+ valence. Consid-ering the present case in which Tl is an impurity this implies that the 2+ impurity state may occur at a higher
