According to the invention, the pile structures of the battery pieces in the assembly are optimized from the regular rectangular pyramid to the inclined rectangular pyramid, and the vertex orientations of the inclined rectangular pyramids on the battery pieces in the assembly are optimized and selected, compared with the battery pieces adopting the regular rectangular pyramid pile structures, the reflection times of the inclined rectangular pyramid pile structures on sunlight can be more than that of the existing regular rectangular pyramid pile structures, so that compared with the existing battery pieces adopting the regular rectangular pyramid pile structures, the reflectivity of the battery pieces is lower, and based on the lower reflectivity, the generating capacity of the assembly can be improved.
