Abstract: The present application discloses a back contact solar cell string group and a photovoltaic module. In one example, a back contact solar cell string group includes at least two solar cell strings. Each solar cell string includes: multiple solar cells arranged along a second direction; and multiple welding strips, where two adjacent solar cells in a solar cell string are electrically connected by corresponding welding strips of the multiple welding strips arranged along a first direction, and a distance between two welding strips adjacent to each other along the first direction is d1. In each solar cell string, welding strips adjacent to two edges of the multiple solar cells along the first direction are end welding strips. A distance between two end welding strips of two solar cell strings adjacent to each other along the first direction is d2, 0.6?d2/d1<1.

Abstract: The present disclosure provides an assembled cabinet with multiple storage units. Each storage unit includes multiple panels and connectors interconnected to form an inner space and an opening. Each of the panels includes a panel frame and a panel sheet that covers the panel frame, with panel corners of the panel frame not being covered by the panel sheet. Each of the connectors has multiple panel corners corresponding to panel corners, and adjacent connector slots are oriented perpendicularly to each other. Further, the storage unit includes corner braces each being inserted into a corresponding connector located around the opening of the storage unit, and the corner braces are installed into available connector slots of the corresponding connectors.

Abstract: A method and device for optimal power flow calculation in power systems based on generalized Nash equilibrium are disclosed.

Abstract: Provided in the present application is a chimeric antigen receptor, including a GPC3 antigen binding domain, an ICDI, ICD2 or ICD3 intracellular signal stimulation domain with amino acid sequences of SEQ ID NOs: 29, 31 and 33, respectively, and an IL-15-IL-15? fusion protein with an amino acid sequence of SEQ ID NO: 7. After the chimeric antigen receptor is transferred into immune cells, especially iNKT cells, the cell proliferation rate, survival time and tumor killing effect can be effectively improved. Further provided in the present application are a corresponding expression vector, a transduction system, a pharmaceutical use, independent ICDI, ICD2 and ICD3 intracellular signal stimulation domains, and an IL-15-IL-15? fusion protein.
