METHOD FOR PREPARING MICROCRYSTALLINE CADMIUM SELENIDE FILM USING ELECTRODEPOSITION AND THE CADMIUM SELENIDE FILM PREPARED THEREBY

摘要

The present invention relates to a method for producing a microcrystalline cadmium selenide (CdSe) film by using an electrodeposition method, sodium citrate (Na ₃ C ₆ H ₅ O ₇ · 3H ₂ O) in a solution of cadmium sulfate (CdSO ₄ ) The pH was adjusted to 7-9 by adding an aqueous solution, and then mixed with an aqueous solution of sodium selenite sulfite (Na ₂ SeSO ₃ ), followed by immersing a counter electrode and a working electrode and applying a voltage thereto. According to the electrodeposition method of the present invention comprising a simple, high-quality cadmium selenide film having a fine hexagonal crystal structure can be easily produced, this film is useful as an electrode in the process of converting light energy into electrical or chemical energy do.
