The battery piece is covered with a layer of filter film, so that the power conversion efficiency of the battery piece is lower and is generally lower than 12%. And the mode of coating a layer of filter film on the battery piece realizes single color, but the method increases the process of coating the filter film and increases the manufacturing cost.
