Abstract: Provided is a photovoltaic module, including: a plurality of solar cell strings arranged at intervals and each including a front surface and a rear surface arranged opposite to each other; a first encapsulation adhesive film and a back panel located on the rear surface of the solar cell string; and first embossing structures provided on one side of the back panel away from the first encapsulation adhesive film. An angle ? between a side surface of the first embossing structure and a plane of the back panel is in a range from 42° to 80°.

Abstract: A mouse monoclonal antibody for antagonizing and inhibiting binding of a vascular endothelial growth factor (VEGF) and its receptor (VEGF-R), and a heavy chain variable region and light chain variable region amino acid sequence thereof. Also disclosed are a humanized preparation process of the antibody and a heavy chain variable region and light chain variable region amino acid sequence of the humanized antibody. The humanized antibody or its derivative can act as an ingredient of a pharmaceutical composition or be prepared into a suitable pharmaceutical preparation, is administered alone or in combination with a chemotherapy drug or other treatment means, and is used in broad-spectrum treatment of various solid tumors such as colon cancer, breast cancer and rhabdomyosarcoma.
