The invention discloses a portable automotive solar cell sunshade improved structure, which comprises a reflecting film, wherein a row of film solar cells are arranged on the reflecting film; the reflecting film is provided with folded edges among the adjacent film solar cells; a cell lead of each film solar cell is connected with a main power line; the solar cell sunshade is provided with a power outgoing line which is connected with the main power line; the cell lead of each film solar cell is divided into an upper cell lead and a lower cell lead according to difference of the anode and the cathode of the film solar cell; the reflecting film is provided with the main power line on the upper edges and the lower edges of the film solar cells in a laid mode; and the two cell leads of each film solar cell are laid along the corresponding folded edges and are finally welded with the main power line. The folded edges are arranged among the film solar cells which are arranged side by side, so that the film solar cells are quite easy to fold, cannot be damaged, and are difficult to age.
