DEFINITION

Classification: 136/243

PHOTOELECTRIC:

(under the class definition) Device which generates an electric potential upon exposure to light, by the direct conversion of the light to electrical energy, i.e., photovoltaic.

(1) Note. Similar structures may be disclosed as having other functions, e.g., rectifying, photoconductive, etc., and some of these photoelectric devices may be disclosed as having several functions. A patent which discloses or claims only a photovoltaic use will be placed here. A patent which claims other uses or which is claimed generically will be placed in another pertinent class, e.g., Class 250, Radiant Energy, or Class 257, Active Solid-State Devices (e.g., Transistors, Solid-State Diodes).
