Research output: Contribution to conferencePaper


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