Abstract: The present disclosure relates to a solar cell and a manufacturing method therefor. The solar cell includes: a base substrate; an electrode layer set on a surface of the base substrate, the electrode layer set including a first electrode and a second electrode, and the first electrode and the second electrode being electrically insulated from each other; a photoelectric layer disposed on a side of the electrode layer set facing away from the base substrate and electrically connected to the first electrode, the photoelectric layer being provided with a first via, and the position of the first via corresponding to the position of the second electrode; and a window layer disposed on a side of the photoelectric layer facing away from the base substrate and electrically connected to the second electrode through the first via.

Abstract: An in-line multi-stage physical vapor deposition chamber is disclosed. The deposition chamber includes a cylindrical shaped main body, multiple dividers disposed within the main body and extending in radial directions to divide the interior space of the main body into multiple fan shaped zones, and a cylindrical shaped substrate holder disposed coaxially with the main body. The substrate holder is rotatable around a central axis, and individual substrates or a continuous flexible substrate is mounted on the substrate holder parallel to the central axis. Multiple metal source holders are disposed on the cylindrical sidewall of the main body in at least some of zones for mounting metal sources. Some zones are provided with heating mechanisms for heating the substrate. A load-lock chamber is connected to the main body for loading and unloading substrates into and from a first zone.
