Selenium alloying has enabled record efficiency for CdTe solar cells by changing the optoelectronic properties of the CdTe absorber layer, though its role has not yet been fully understood. Now, non-radiative charge-carrier recombination in the bulk of the CdSeTe layer is revealed to be lower in grains with higher Se concentration.
