Abstract
Description
technical field
[0001] The invention belongs to the field of photoelectric material and product manufacturing, and relates to a material and product and a manufacturing method thereof, in particular to a photoelectric conversion device and a manufacturing method thereof. Background technique
[0002] The sun is a hot gaseous sphere, a huge, long-lasting, inexhaustible source of energy. As a clean energy source without any pollution, solar energy has attracted more and more attention and great interest from all over the world.
[0003] Human beings have a long history of utilizing solar energy. As early as the Warring States period more than 2,000 years ago, our country knew to use steel four-sided mirrors to focus sunlight to ignite fires; use solar energy to dry agricultural and sideline products. So far, the utilization of solar energy has become increasingly widespread, including solar thermal utilization, photovoltaic utilization of solar energy and photochemical utili...
Examples
Embodiment Construction
[0033] The present invention will be further described below through specific examples, but the present invention is not limited within the scope of the examples.
[0034] The polymer material / metal laminate sheet made by the twin-screw extruder (Germany JP Industrial Technology Equipment Co., Ltd., model JSK26, screw aspect ratio: 30) is used as the substrate, and the surface and bottom surface of the substrate are Plane, the polymer material is polyimide, the metal layer is aluminum, and the metal layer is used as the metal back electrode layer. A layer of zinc oxide is coated on the surface of the metal back electrode layer to form a transition layer; The distribution ratio is Cu In 1-x Ga x (Se 2 or S 2 ), wherein x=0.33, coating a layer of Cu InGa compound, including 9% PVA surfactant, lubricant and processing aid in the compound, applying heat to it, and then heat treatment, the temperature is 150-410 ° C, During heat treatment, Se 2 or S 2 steam to form a light-ab...
