Resumen:
This study presents the synthesis of the Cu2O thin films by chemical bath deposition. The effect of temperature and the amount of triethanolamine (TEA) on the film's structural, optical, and electrical properties is studied. It is found that regardless of the amount of TEA, as the deposit temperature increases, thicker films are formed with a better-defined morphology and larger particle size. This causes the structural disorder to decrease and consequently, reduces the conductivity, and then increases the Bandgap value. The increase in TEA causes a greater complexation of the copper ion, which implies that the reaction is slower, and consequently, the oxide precipitates more slowly, and a film with more controlled growth is formed, resulting in thicker films with more homogeneous morphology, and larger particle size. It is noteworthy that thicknesses greater than one micron were achieved, which is remarkable for its applications in diverse fields. This opens the possibility of using this material through this technique in solar technology such as photovoltaics. © 2023 IEEE.
