The invention relates to a solar battery piece packaging glue structure and a preparation method thereof. The structure comprises a packaging glue layer and at least one partitioning membrane layer, or comprises a packaging glue layer, at least one layer of partitioning membrane and at least one adhesive layer distributed on one side, which is close to a battery piece, of the partitioning membrane, wherein the partitioning membrane is compounded with the packaging glue layer, or the partitioning membrane is compounded with the packaging glue layer and the adhesive layer; the flowability of the partitioning membrane is smaller than that of the packaging glue layer. According to the solar battery piece packaging glue structure, as one layer of the partitioning membrane with very low flowability is compounded with the packaging glue and the flowability of the partitioning membrane self is lower than that of the packaging glue, the packaging glue is harder to overflow, and moreover a good partitioning function is achieved for overflowing of the packaging glue with high flowability. When the structure is laminated, the packaging glue of a cross-linking system with high flowability at a lower layer can be fused with the partitioning membrane with low flowability at an upper layer at high temperature, so that sufficient binding force can be still maintained.
