Abstract

The invention proposes a perovskite photovoltaic composite material for 3D printing forming. The perovskite photovoltaic composite material is characterized by being formed by grinding raw materials of lead halide, halogenated methylamine, calcium oxide, copper oxide, titanium oxide and bismuth trioxide and coating the surface with a layer of colloid. The perovskite photovoltaic composite material has favorable mobility when used for 3D printing and has binding capability in a hot environment of 80-90 DEG C, a uniform perovskite thin film with a thickness of 100-300 nanometers can be rapidly formed through 3D printing and used as a light absorption layer of a photovoltaic battery, and the battery efficiency reduction caused by sensitivity of perovskite to moisture and oxygen is effectively reduced.

Description

technical field [0001] The invention belongs to the field of 3D printing manufacturing materials, and specifically relates to a perovskite photovoltaic material. The perovskite photovoltaic composite material can be used to prepare a photovoltaic film through a 3D printing manufacturing technology. It further relates to a preparation method of the perovskite photovoltaic composite material. Background technique [0002] After more than 60 years of development of solar cell materials, there are many different types. Mainly include monocrystalline / polycrystalline silicon, gallium arsenide, cadmium telluride, copper indium gallium selenide, dye sensitization, etc. At present, only monocrystalline / polycrystalline silicon solar cells have been widely used, and other types of solar cells are limited in practical application due to the shortcomings of scarce raw materials, toxicity, low efficiency, and poor stability. However, the production cost of monocrystalline / polycrystallin...
