Abstract: The present invention relates to a ceramic slate with a colored jade effect and a preparation method comprising: pressing and forming raw materials containing a ceramic base material and colored glass fragments to obtain a ceramic green body; drying and firing the ceramic green body to give a ceramic slate with colored jade effect particles dispersed on the surface of the green body; wherein, the colored glass fragments account for 3 wt % to 5 wt % of the ceramic base material. Since colored glass waste instead of frits and pigments is used to prepare the ceramic slate with the colored jade effect, the ceramic slate does not have the phenomenon of pigment dispersion after high-temperature firing, and the surface of the fired ceramic slate shows a shape of micro-protrusion, so that the polished tile surface is smoother and free from pits, resulting in a better tile surface effect.

Abstract: The invention relates a full-laser scribing method for a flexible stainless steel substrate solar cell module, comprising: preparing an insulating layer and a molybdenum layer on a stainless steel substrate in sequence; using a laser I to scribe the prepared insulating layer and molybdenum layer to form a first scribed line (P1); preparing the following film layers in sequence on the molybdenum layer in which P1 has been scribed: a CIGS layer, a cadmium sulfide layer and an intrinsic zinc oxide layer; using a laser II to make scribe and thus form a second scribed line (P2), wherein the second scribed line P2 is parallel with the first scribed line P1; and preparing an aluminum-doped zinc oxide layer on the intrinsic zinc oxide layer in which P2 has been scribed, and using a laser III to make scribe and thus form a third scribed line (P3), wherein the third scribed line P3 is parallel with the first scribed line P1.
