Solar cell and fabrication method therefor, coating device and solar cell production system

A coating device for preparing a solar cell, comprising:

• a first physical vapor deposition chamber used to prepare a first transparent conductive layer on a solar cell precursor of the solar cell;
• a chemical vapor deposition chamber in communication with the first physical vapor deposition chamber, wherein the chemical vapor deposition chamber is used to prepare a first interlayer film on the first transparent conductive layer;
• and
• a second physical vapor deposition chamber in communication with the chemical vapor deposition chamber, the second physical vapor deposition chamber being used to prepare a second transparent conductive layer on the first interlayer film, wherein the first transparent conductive layer, the first interlayer film and the second transparent conductive layer are stacked in sequence to form a first transparent conductive film.
