Solar cell provided with local layered electrode, preparation method and cell assembly

The invention discloses a solar cell provided with a local layered electrode, a preparation method and a cell assembly, the solar cell comprises a cell substrate and electrodes arranged on the cell substrate, and the electrodes are arranged on the front surface and/or the back surface of the cell substrate; an electrode groove is formed in the battery base body, and the electrode is a layered electrode; the layered electrode comprises a groove electrode located in the electrode groove, and the groove electrode sequentially comprises a current collection film and a conductive layer arranged on the current collection film from the bottom of the electrode groove to the outside; and the current collection film is at least one or a combination of more of Al, AlTi and AlW. Compared with the prior art, the solar cell provided with the local layered electrode has the following advantages that the current collection film has a good current collection effect, and severe metal recombination cannot be generated between t
