Here, we have developed CdSexTe1-x/CdTe bilayer deposition for graded solar cell technolgoly technolgoly. Smoothly graded Se profiles with > 16 efficiency with Jsc=28 mA/cm2 and 20-ns bulk lifetime has been observed observed. The CdSeTe reveals longer carrier lifetimes than CdTe within the same device.
