Patent ID: 8297226

Claim:
A deposition box for silicon-based thin film solar cells, comprising: an electrode plate component; a signal feed-in component; and a chamber, wherein: electrode plate component includes a cathode plate and a shielding cover of the cathode plate, the shielding cover includes a ceramic insulating layer and a shielding layer, the chamber is a movable chamber with rollers and contains installed the electrode array composing of the electrode plate; a feed-in port is located in a sunken circular or semicircular area at the center of the backside of the cathode plate of the electrode plate component; the signal feed-in component connecting with the feed-in port by surface contact connects with the negative electrode of the feeding Very High Frequency (VHF) power supply signals; one end surface of the signal feed-in component is circular or semicircular; the shielding cover of the cathode plate corresponding to the feed-in port has a through hole; the cathode plate is insulated from the shielding cover; the electrode array has at least one set cathode plates and one anode plate; and the cathode plate is single-surface discharging, and the shielding cover covers entire back and side surfaces of the cathode plate.
