A discharge electrode array for a silicon-based thin film solar cell deposition chamber is provided, relating to solar cell technologies. The discharge electrode array includes a signal feed component having a rectangular-shaped end, a flat waist corresponding to a feed-in port located in a hallowed rectangular area on a center region of a cathode plate having a shielding cover, connecting a feed-in power supply signal by surface contact. The electrode array includes at least a set of cathode plates and an anode plate, with two cathode plates sharing or surrounding one anode plate. Uniform large area and stable discharge driven by the RF/VHF power supply signal can be achieved, and the standing wave and the skin effect can be effectively removed. The production efficiency can be improved and the cost can be reduced.

Discharge electrode array for thin-film solar cell deposition

The present invention discloses a surface feed-in electrode structure for thin film solar cell deposition, relating to solar cell technologies. The surface feed-in electrode structure uses a signal feed-in component with a flat waist and a semicircular feed-in end to connect the signal feed-in port by surface contact. The signal feed-in port is located in a hallowed circular area of a center of the backside of a cathode plate, and feeds in an RF/VHF power supply signal. An anode plate is grounded. The cathode plate is insulated with a shielding cover, and a through-hole is configured on the shielding cover. The effects include that, by using the surface feed-in at the center of the electrode plate, the feeding line loss of single-point or multi-point feed-in configurations can be overcome. Uniform large area and stable discharge driven by the RF/VHF power supply signal can be achieved, and the standing wave and the skin effect can be effectively removed. The production efficiency can be improved and the cost can be reduced.

Surface feed-in electrodes for deposition of thin film solar cell and signal feed-in method thereof

A movable jig for a silicon-based thin film solar cell comprises parallel electrode plates (), a supporting frame and a signal feed-in assembly (). The supporting frame is a movable frame and its side frame () is grounded. A shield device is set on the jig or among jig arrays themselves for preventing from being disturbed. The signal feed-in assembly is a conductor and its middle portion and head portion form a ladder cylinder, and one end surface (-) of the signal feed-in assembly is triangular and can surface contact and connect with a sunken triangular feed-in port (-) in the center area of the back surface of the cathode plate () of the electrode plates, so the radio frequency/the very high frequency power supply signal can be fed in. Through the way of the surface feed-in in the center of the electrode plate, the consumption caused by the feeder distance in the way of one point feed-in or multipoint feed-in can be reduced, the large area stable discharge of the uniform electric field can be obtained, the production efficiency can be increased and the cost can be decreased.
