The short-wavelength spectral response of a thin film CuInSe2 device is improved by a thin (~ 500 A) undoped CdS layer and a 1 pm ZnO conducting window layer. The ZnO acts as an antireflection coating and permits photons of wavelength above 360 nm to be absorbed in the CuInSe2. A 25% photocurrent en
Current-voltage (J-V) and capacitance-frequency (C-F) measurements were taken for all-sputtered CdS/CuInSe2 solar cell heterojunctions, in the range 100 Hz -10 MHz, to investigate the effect of interface states on the conduction mechanism. The samples analyzed had different compositions for the chal
