Abstract
Liquid-semiconductor photocells using chalcogenide semiconductors have been advanced recently to the point where they compete favorably with silicon devices for solar power conversion. However, in common with silicon devices, the semiconductor needs to be a single crystal. This fact makes solar power impractically expensive. According to this invention, the chalcogenide semiconductor is made by anodizing cadmium or bismuth in a sulfide, selenide or telluride electrolyte. The anodized element, when operated photovoltaically in an electrolyte similar to the anodizing solution, produces useful power conversion and is relatively inexpensive.
