Patent ID: 8438989

Claim:
A surface feed-in electrode structure for silicon thin-film solar cell deposition, comprising: an electrode plate component having an anode plate and a cathode plate; and a signal feed-in port configured on the electrode plate component, wherein: the anode plate of the electrode plate component is connected to a positive end of a power supply signal and is grounded; the signal feed-in port is located in a hallowed circular area at a center area of a backside of the cathode plate; a signal feed-in component is connected to the signal feed-in port by surface contact and to a negative end of a radio frequency (RF) or very high frequency (VHF) power supply signal; the RF/VHF power supply signal is fed in a surface feed-in mode; one end of the signal feed-in component is in a semicircular shape; and a through-hole is configured on a shielding cover of the cathode plate.
