Abstract

The invention provides a perovskite photovoltaic composite material used for 3D printing and forming. The perovskite photovoltaic composite material is characterized in that the perovskite photovoltaic composite material is prepared from the raw materials of lead halide, methylamine halide, calcium oxide, copper oxide, titanium oxide and bismuth trioxide through grinding; the surface is coated with a layer of colloid, so that high fluidity is achieved in 3D printing, and adhesion property is shown in a thermal environment of 80-90 DEG C; a uniform perovskite thin film with thickness of 100-300nm can be quickly formed through 3D printing and quick forming; and when the composite material is used for an optical absorption layer of a photovoltaic battery, degradation of the battery efficiencycaused by water content and oxygen sensitivity due to the perovskite can be avoided effectively.
