Photoelectrochemical Conversion of $SnO_2$ Films Deosited by Spray Pyrolysis
The photoelectrochemical conversion in SnO2 films deposited by spray pyrolysis using SnCl4-alcohol solution and N2 gas has been studied. The photocurrent increases with increasing deposition temperature up to 40$0^{circ}C$ and then decreases, and the electron affinity decreases as the deposition temperature increases to 40$0^{circ}C$. As the concentration of the spray solution increases, the photocurrent reaches a maximum value at the concentration of 0.05M, and the electron affinity is consistent. As the thickness of the film increases, the photocurrent increases with a maximum value at the thickness of 4600$AA$, and electron affinity does not change.
