The utility model provides a flexible soft solar cell with light weight and convenient manufacture, which comprises a soft PCB board, an EVA sheet, a cell slice pack formed by a plurality of cell slices which are connected in series, an EVA sheet and a light-transmitting film, which are sequentially arranged from bottom to top and laminated, wherein a power supply pin of the cell slice pack is connected with the line of the soft PCB board. The solar cell utilizes the soft PCB board to substitutes for the traditional lower substrate material, and uses the light-transmitting film layer to substitutes for an upper cover plate, thereby not only reducing the weight of the solar cell, but also greatly increasing the softness of the solar cell and meeting the requirements of different shapes; and in addition, the manufacturing method is basically same as the technological process for manufacturing the traditional flat plate solar cell, the equipment does not require any improvement, and the promotion is easy.
