Study on the effect of annealing on the electrical properties of n-type cuprous oxide

Cu2O photoelectrodes for solar water splitting: Tuning photoelectrochemical performance by controlled faceting

“…Cu 2 O can be synthesized by various methods such as sputtering [17,18], chemical vapor deposition [19,20], thermal oxidation [21], chemical bath deposition [22], and electrodeposition [23][24][25].…”

Study of the Electrodeposition of Cu2O Thin Films from DMSO Solution

“…This because the pH and operating temperature are crucial parameters in order to determine the crystalline character, electronic properties and morphology of the films. [11][12][13][14][15][16][17] Other electrolytes including copper acetate + acetic acid/acetate solutions, 18 copper nitrate [19][20][21] and CuSO 4 + citric acid/citrate solutions 22 have been employed in the electrodeposition of Cu 2 O with different properties and morphologies.…”

Methods for improving n-type photoconductivity of electrodeposited Cu2O thin films

“…Photovoltage spectral response of the same sample used in figure 5 Cu 2 O films electrodeposited at pH 6.5 further investigated by annealing in air at various temperatures below 200 °C for different durations. Although, previously there have been reports on annealing of electrodeposited n-Cu 2 O thin films in N 2 and in air, an optimum condition for the removal of p-type conductivity was not reported [6,32]. The general observation was that depending on the annealing temperature the duration of annealing required to obtain films without producing p-type photoresponse is varied.…”
