Abstract
Abstract A method for manufacturing a photoelectric device having a plurality of photoconductive layers comprising the steps of forming on a surface of a semimanufactured article a layer of mixed suspension material consisting of powdery photoconductive material, binder material and volatile diluent, volatilizing said volatile diluent, repeating these steps to laminate the desired number of layers, and subjecting the laminated layers to a single heat treatment, thereby to set the photoconductive layers simultaneously. A photoelectric device including a spacer frame between the electrodes, said frame encircling at least one photoconductive layer.

Claim 2
Independent Claim
190 words
A method for manufacturing a photoconductive device comprising a composite laminate of photoconductive layers, each of said layers including a photoconductive powder and a thermosetting binder and said laminate being provided with a foraminous electrode, comprising the steps of: a. disposing a composite spacer frame having separable upper and lower frame members of insulating material on a substrate; b. applying a mixture comprising a photoconductive powder, a thermosetting binder and a volatile diluent on said substrate within said frame; c. leveling the surface of said mixture to Substantially the height of the top of said frame; d. volatizing said volatile diluent; e. repeating steps (b), (c) and (d) at least once to form a composite laminate having a plurality of photoconductive layers; f. removing said upper frame member; g. disposing a foraminous electrode on said composite laminate; h. applying a further mixture of photoconductive material, thermosetting binder and volatile diluent on said composite laminate; i. covering at least a part of said foraminous electrode with said further mixture; j. volatizing the diluent in said further mixture; and k. heating said composite laminate to thermally set said photoconductive layers substantially simultaneously.
