A dye-sensitized solar cell using a photoelectric transformation electrode. The assembly is such that the armature core can be formed from two laminated pieces that are rigidly connected to each other and held against axial movement. A signal indicating the end of one line is counted by a line counter of a memory device. Each color card has a pigmented lacquer deposited on color card and the activator solution is used to dissolve the lacquer off of the surface of the card.
