A method and system for fabricating solid-state energy-storage and energy-conversion devices including fabrication of films for devices without an anneal step, especially for the fabrication of supercapacitors and photovoltaic cells. The pixel detecting element comprises: a pixel electrode for receiving charges, a storage capacitor for storing the received charges, and a thin film transistor for controlling outputting of the stored charges. An information sending part sends the packet of the cell. The outer surface the outer cover is black or dark color before the irradiation with laser light, but thus formed scale is white or blight color having a whiteness of 60% or more.
