"Structure" of an about 12 cm × 12 cm solar cell.
In this case an electronic parameter is encoded in the colors
(roughly the efficiency of converting light energy into electric energy).
The interesting features is the nested system of lines ("striations") that show the position
of the solid-liquid interface at different times during solidification.
Solidification progressed from the bottom to the top
