titleOfInvention | PERC solar cells of photoelectric conversion efficiency and preparation method thereof can be improved |
abstract | The invention discloses PERC solar cells that can improve photoelectric conversion efficiency and preparation method thereof, the solar cell includes the back of the body silver electrode set gradually from bottom to top, Al-BSF, back side silicon nitride, backside oxide aluminium film, P-type silicon, N-type silicon, front side silicon nitride film and positive silver electrode, Al-BSF is connected by carrying on the back aluminum strip with P-type silicon, the P-type silicon is the silicon chip of battery, N-type silicon is the N-type emitter diffuseed to form in front side of silicon wafer, the front side silicon nitride film is deposited on front side of silicon wafer, the backside oxide aluminium film is deposited on the silicon chip back side, backside oxide aluminium film after the silicon chip deposition front side silicon nitride film described in redeposition, and silicon chip back side is cleaned before the backside oxide aluminium film is deposited.The battery can be obviously improved the passivation effect of backside oxide aluminium film, improve the open-circuit voltage and short circuit current of battery, so as to promote the photoelectric conversion efficiency of battery.The present invention discloses the preparation methods of the solar cell. |
