Abstract
The newly introduced setup for 'absolute' constant photocurrent method allows measurement of the optical (photocurrent) absorption spectrum, alpha(E), directly in absolute units (cm(-1)) without additional cali bration and undisturbed by interference fringes, Computer simulation w as performed to demonstrate the precision of the measurement and to ex plain residual interferences sometimes observed. The residual interfer ences are shown to be direct fingerprints of an inhomogeneous defect d istribution.
