Preparation Of Tin Selenide Thin Film Semiconductor By Electrochemical Deposition And Electroselenisation

Preparation Of Tin Selenide Thin Film Semiconductor By Electrochemical Deposition And Electroselenisation

Electrochemical preparation of tin selenide thin film semiconductor for photoelectrochemical cells (PECs) was studied. The film has been potentiostatically deposited on tin substrate at room temperature from aqueous solution containing SnCl2 and Na2SeO3. The effect of the electrodeposition potent...
