Abstract: The technical field of active substance preparations is belonged to, and provided are astaxanthin pickering emulsion with colon targeted delivery function, and a preparation method and application method thereof. The preparation method includes the following steps: S1, reparation of deacetylated-oxidized chitin nanofiber (DE-TO-ChNF)/carboxymethyl konjac glucomannan (CMKGM) nanogel; S2, preparation of astaxanthin oil phase; and S3, preparation astaxanthin pickering emulsion. Natural polysaccharide derivatives DE-TO-ChNF and CMKGM are used as raw materials, and stable crosslinking between covalent bonds and non-covalent bonds are formed between molecules in a composite system through the NHS/EDC, so as to form a stable nanogel. Then the nanogel is used as emulsifier and flaxseed oil rich in astaxanthin is used as oil phase to prepare the astaxanthin pickering emulsion by homogenization.

Abstract: A solar cell (10) includes a sector-shaped cell body, front-surface electrodes (11) and a plurality of fine grid lines (12) are provided at a front surface of the cell body, the front-surface electrodes (11) and the fine grid lines (12) intersect and are electrically connected, back-surface electrodes (13) are provided at a back surface of the cell body, and a quantity of the front-surface electrodes (11) and a quantity of the back-surface electrodes (13) are equal. The solar-cell module includes a plurality of solar-cell strings (20) that are sequentially arranged and are electrically connected to each other, a plurality of protrusions (23) are provided on two sides of the solar-cell strings (20), a depression part (24) is formed between every two neighboring instances of the protrusions (23), and the protrusions (23) of each of the solar-cell strings (20) protrude into the depression parts (24) of neighboring solar-cell strings (20).
