Abstract: A photovoltaic module, including a cell string including cells, including a substrate including a first side and a second side. The first side includes first and second regions. The first region includes a boron-doped silicon structure. The second side includes third and fourth regions. The third region includes a tunneling oxide layer and a phosphorus-doped conductive layer. The cell includes first and second surfaces, and includes a first electrode on the first surface and a second electrode on the second surface. The first surface of the first cell and the second surface of the second cell are located on a same side. The first electrode of the first cell is connected to the second electrode of the adjacent second cell through a solder strip. The second electrode of the first cell is connected to the first electrode of the adjacent second cell through the solder strip.

Abstract: Provided is a method for manufacturing a solar cell, including: providing a substrate having a first surface and a second surface opposite to each other forming a first doped layer on the second surface and concurrently forming a second doped layer on a target doped dielectric layer; patterning the second doped layer, including removing portions of the second doped layer; etching away the portion of the target doped dielectric layer over the first region; etching away a portion of the target doped semiconductor layer over the first region, and etching away a portion of the second doped layer over the second region; and etching away the portion of the target doped dielectric layer over the second region, a portion of the target doped semiconductor layer over the second region being reserved as a doped semiconductor portion. The respective first regions and the respective second regions are alternatingly distributed.

Abstract: A data management system comprises: a storage appliance configured to store a snapshot of a virtual machine; and one or more processors in communication with the storage appliance. The one or more processors are configured to perform operations including: identifying a plurality of shards of the virtual machine; requesting a snapshot of each of the plurality of shards; receiving the shards asynchronously; ordering the received snapshot shards sequentially into a results queue; and storing a single snapshot of the virtual machine based on the ordered snapshot shards. Operations may further include maintaining a flow control queue that limits the number of snapshot shards requested.
