Photophysical investigation of charge recombination in CdS/ZnO layers of CuIn(S,Se)2 solar cell
Excitation wavelength dependent femtosecond transient photocurrents were measured on CuIn(S,Se) 2 solar cell devices, in the range of 330 nm–1300 nm. Below 450 nm wavelength excitations, charge recombination in CdS/ZnO layers is found to be responsible for longer decays and low...

| description |
Excitation wavelength dependent
femtosecond transient photocurrents were
measured on CuIn(S,Se) 2 solar cell devices, in
the range of 330 nm–1300 nm. Below 450 nm
wavelength excitations, charge recombination
in CdS/ZnO layers is found to be responsible
for longer decays and lower EQE.
Femtosecond pump-probe measurements also
support the charge transfer and
recombination in CdS/ZnO layers. These
measurements will be helpful to design high
efficiency CISSe solar cells, by selecting
suitable buffer layers. |
