The application relates to a large electric partition door and a mounting method thereof, which comprises a plurality of partition door units and guide rails for moving and mounting the partition door units, the partition door units are independently mounted, the partition door units and the guide rails are connected through lifting wheels, the lifting wheels drive the partition door units to move on the guide rails, the guide rails are fixed on a floor through a plurality of track fixers, two lifting wheels are arranged on the top of each partition door unit, a steel keel is arranged in the partition door unit, support frames are arranged at the two ends of the steel keel, and the support frames are connected through supporting rods. In the use process, when the lifting wheels on the inner track move to the turning track connected with the inner track during the outward movement of the partition door unit, the steering wheels on the lifting wheels are matched with the rack to drive the partition door unit to deviate, the partition door unit is ensured to deviate at the corresponding position during the movement process, and the folding space is conveniently inclined and stored.

This invention discloses a solar cell and its fabrication method, components, and system. The solar cell includes a silicon substrate, a doped layer and a passivation layer sequentially stacked on the back side of the silicon substrate. The passivation layer has electrode trenches that locally expose the doped layer, and the electrode trenches are provided with a back electrode. The back electrode includes a seed metal silicide layer, a seed metal oxide thin layer, a mixed conductive layer, and an outer metal layer sequentially stacked on the back side of the locally exposed doped layer. The seed metal silicide layer is one or more layers selected from molybdenum silicide, nickel silicide, and titanium silicide layers; the seed metal oxide thin layer is one or more layers selected from molybdenum oxide, nickel oxide, and titanium oxide thin layers; and the thickness of the seed metal oxide thin layer is no greater than 20 nm. This solar cell has a novel electrode structure, which can promote improvements in electrode structure and performance, and reduce costs. The novel electrode structure of this solar cell exhibits good current transport performance and low metal recombination loss.
