Abstract
The influence of the reflection of photoelectrons from the surface photo-EMF in thin semiconductor films and compare it with the bulk photo-EMF. It is shown that the reflected photovoltage can prevail over the bulk of the electromotive force only in samples with a large mean free path with a strong absorption of light. In thin films reflected the photo-EMF, apparently observed with other types of photo-EMF and the interpretation of the experimental results can be interpreted as the volume electromotive force.
