In a photocell, in particular for detecting U.V. radiation, comprising a plate cathode (1), an anode (2) and lead-in and lead-off lines (3, 4; 5, 6) respectively, which are sealed in a glass envelope, the plate cathode consists of a sheet metal strip (13) which, at its ends (11, 12), is connected to said lead-in lines (3, 4), while said anode consists of a wire electrode (16) which, at its ends (14, 15), is connected to said lead-off lines (5, 6) and which is arranged on the plate cathode side facing the radiation to be detected substantially parallel to and spaced apart (d) from said plate cathode. By this it is possible to achieve less overall costs of production and at the same time very good efficiency.
