Title: Method for electrolyzing copper
Inventor: OTO SHUICHI
IPC: C25C1/12
Filed: 1985-11-15
Abstract: PURPOSE:To electrolyze copper economically by carrying out electrolysis with an electrolytic soln. at a specified relatively low temp. so as to reduce the loss of silver by transfer to electrolytic copper. CONSTITUTION:When copper is electrolyzed, electrolysis is carried out with an electrolytic soln. at such a relatively low temp. as 53-58 deg.C so as to inhibit the transfer of silver in the electrolytic soln. to electrolytic copper. A profit brought by the reduced loss of silver exceeds a loss caused by the increase of electric power for electrolysis required by the lowered temp. of the electrolytic soln., so copper can be economically electrolyzed.

Abstract: PURPOSE:To inhibit the lowering of open circuit voltage in a photosensor adopting a 1000Angstrom  texture transparent conductive film while simultaneously realizing the increase of short-circuit currents by forming an irregular shape having a truncated pyramidal or pyramidal shape to a surface on the semiconductor film side of a light-transmitting conductive film and limiting a crossed axes angle formed by the ridge of said truncated pyramid or pyramid and the perpendicular of said main surface while also specifying the height of said truncated pyramid or pyramid in the vertical direction to said main surface. CONSTITUTION:A reaction gas is injected onto the surface of a substrate 1 arranged to a thermal CVD device, and an SnO2 film having an irregular shape is formed. A crossed axes angle with the perpendicular of the main surface of the substrate 1 formed by the ridge of the truncated pyramid or pyramid of a light-transmitting conductive film 2 is brought to a value from 30 deg. to 60 deg. by controlling the conditions of formation at that time. Consequently, the difference of the film thickness A and film thickness B of a P layer on a texture transparent conductive film can be reduced, thus inhibiting the lowering of open circuit voltage. Height shaped by said truncated pyramid or pyramid in the vertical direction to the main surface of the substrate 1 is brought to a value from 1000Angstrom  to 3000Angstrom . Accordingly, the scattering of light projected to a photosensor is increased, and the lowering of said open circuit voltage is suppressed while the augmentation of said short-circuit photocurrents can be attained.
