Abstract: In one implementation, we propose the UnfoldingOperator, which unfolds/flattens an unorganized input 3D point cloud onto a regular 2D grid. Given an input point cloud, an input 2D grid and the reconstructed point cloud produced by the FoldingNet, our proposal maps the input point cloud onto the 2D grid based on the reconstructed point cloud, leading to a 3-channel image. Alternatively, instead of using an image alone to represent a point cloud, the point cloud is decomposed into a codeword and a 3-channel residual image. This residual image is obtained by subtracting the reconstructed point cloud from the original input. The proposed UnfoldingOperator can be applied to point cloud compression, leading to a corresponding compression system that we call UnfoldingCompression. The UnfoldingCompression can work with the TearingCompression, where we can adaptively choose whether to use the UnfoldingCompression or TearingCompression.

Abstract: The solar cell includes a silicon substrate, multiple first electrodes, and multiple second electrodes. The solar cell further includes a tunneling oxide layer, multiple doped polysilicon layers, and at least one barrier layer. The at least one barrier layer is arranged between every adjacent two doped polysilicon layers in the multiple doped polysilicon layers, and the multiple first electrodes are electrically connected to different doped polysilicon layers. The solar cell provided according to the present application can reduce the total thickness of the polycrystalline silicon layer, so that a thinner polycrystalline silicon layer can reduce parasitic absorption, thereby increasing short-circuit current. Moreover, the risk of slurry burning through the tunneling oxide layer is reduced by the barrier layer, while reducing metal recombination, which increases the open circuit voltage of the solar cell, thereby improving the photoelectric conversion efficiency of the solar cell.
