Abstract : The conditions necessary for the production of various types of photovoltages are described. These are: photovoltages due to homogeneous or inhomogeneous excitation and subsequent production of free carriers in the photoconductor; photovoltages due to collisions of excitons with the electrode whereby the excitons are produced in the photoconductor but do not produce free carriers in this material; photovoltages due to chemical processes p9oduced in the photoconductor or in the electrode material; photovoltages much larger than the band gap of the photoconductor. The theory of these photovoltages is given for various conditions. Finally the relationship between photovoltages and rectification is given. (Author)
