Abstract

The invention discloses a high-performance crystalline silicon battery assembly and a solar battery panel. The battery assembly includes a plurality of crystalline silicon battery strings, bus bars and two diodes, wherein the crystalline silicon battery strings are formed by connecting a plurality of small crystalline silicon battery pieces, the small crystalline silicon battery pieces are formedby cutting photovoltaic battery pieces, and at least three small crystalline silicon battery pieces are cut from one photovoltaic battery piece, a plurality of crystalline silicon battery strings areconnected in one or more connection modes of series connection, parallel connection and series-parallel connection to form the crystalline silicon battery assembly, four diodes are arranged at leading-out ends of the crystalline silicon battery assembly, and the leading-out ends of the crystalline silicon battery assembly are arranged at middle parts of two opposite sides or one side of the long side of the crystalline silicon battery assembly. The battery assembly is advantaged in that the output power of the assembly can be improved, overall mechanical load resistance of the assembly is improved, and hot spot resistance is improved.
