Processing device based on electrochemistry and processing method using same

A processing device based on electrochemistry, comprising:

• a platform which is electrically conductive;
• a light source;
• a container configured to store an ionic liquid;
• and
• at least one modeling mechanism;
• wherein the at least one modeling mechanism is arranged facing the platform;
• and the at least one modeling mechanism and the platform are movable with respect to each other;
• the at least one modeling mechanism comprises a photoelectric wheel which is rotatable;
• an outer surface of the photoelectric wheel is able to be applied with the ionic liquid from the container;
• wherein the photoelectric wheel comprises a transparent conductive layer and a photoconductive layer bound together from inside to outside;
• the transparent conductive layer is electrically connected to the platform;
• the photoconductive layer comprises a P-type semiconductor layer and an N-type semiconductor layer;
• when the P-type semiconductor layer and the ionic liquid are electrically connected, the N-type semiconductor layer is electrically connected to the transparent conductive layer;
• and
• when the N-type semiconductor layer and the ionic liquid are electrically connected, the P-type semiconductor layer is electrically connected to the transparent conductive layer;
• and
• a light beam emitted by the light source passes through the transparent conductive layer towards the platform to selectively irradiate the photoconductive layer.
