Abstract

A cell formed on the conducting surface of a substrate, where the surface temp. is held constant by partly immersing the substrate in a molten bath. A soln. contng. several cpds. is sprayed on the surface, forming the first microcrystalline layer of a heterogeneous junction the spraying speed being regulated so the surface temp. is held constant. At least one second layer of the junction is then deposited and electrodes put on this top layer. The first layer is pref. evaporated with the help of intense ultra-violet light and one of the electrodes is a rectifying junction only permitting one-way passage of the current. The advantages are improved performance and lower scrap.
