In this work we report on the coloring of perovskite solar cells (PSC) by combining the ease of freedom in design of the solar cell's shape with the bright color of luminescent down-shifting (LDS) layers. Both the perovskite solar cell and the LDS layers are fabricated with digital inkjet-printing processes, such that the perceived color of the devices can be tuned independently from the shape of the device. The results demonstrate that a strong color perception of the PSCs with the use of luminescent materials of various colors can be achieved at a relatively small (similar to 17%) reduction of power conversion efficiency.
