CdSe films are coated with small thickness(20-50nm) nanocrystalline TiO2 film by electrodeposition or chemical bath deposition methods and PEC properties of CdSe and CdSe/TiO2 sandwich structure are studied. The photoactivity of CdSe and CdSe/TiO2 films deposited on titanium substrate is studied in aqueous electrolyte of 1M NaOH solution. Photocurrent and photovoltage obtained were of the order of 2-4 mA/cm2 and 0.5V, respectively, under the intensity of illumination of 100 mW/cm2. 한국수소및신에너지학회 태양광과 물로부터 수소생산을 위한 광전기화학전지의 CdSe/TiO2 전극 CdSe/TiO2 electrode of photoelectrochemical(PEC) cell for hydrogen production from water using solar energy Article 2 한국수소및신에너지학회논문집, v.16, no.2, pp.130 - 135 한국수소및신에너지학회논문집 16 2 130 135 kci other ART000961729 광전기화학전지 수소생산 물분해 태양광 광부식 보호막 Photoelectrochemical cell H2 production Water splitting Solar light Photocorrosion Protection film
