COPPER DELAFOSSITE TRANSPARENT P-TYPE SEMICONDUCTOR: METHODS OF MANUFACTURE AND APPLICATIONS

摘要

Methods for fabrication of copper delafossite materials include a low temperature sol-gel process for synthesizing CuBO2 powders, and a pulsed laser deposition (PLD) process for forming thin films of CuBO2, using targets made of the CuBO2 powders. The CuBO2 thin films are optically transparent p-type semiconductor oxide thin films. Devices with CuBO2 thin films include p-type transparent thin film transistors (TTFT) comprising thin film CuBO2. as a channel layer and thin film solar cells with CuBO2 p-layers. Solid state dye sensitized solar cells (SS- DSSC) comprising CuBO2 in various forms, including "core-shell" and "nano-couple" particles, and methods of manufacture, are also described.
