Yield curves for hole g&ration in organic crystals through hot hoI& in metal contacts are attributed'to an effeciive dissipation of surplus energy rather than to a broad valence band in orianic crystals.

β¦ Synopsis
At the surface of an organic insuL?tor uystal in contact with an electrolytic solution a charge carrier experiences the attractive aMombic potential of its image and counter charge in the solution. The escape of a defectelectron from destruction through activated reduced redox ions has been caiculated with a simple onedimensional diffusion model. Satisfactory agreement has been obtained with the experimental result
