Abstract

The invention discloses a color cadmium-telluride thin-film solar cell and a preparation method thereof. The color cadmium-telluride thin-film solar cell is composed of a glass substrate layer, a transparent conductive film layer, a window layer, an absorption layer, a back contact layer, a back electrode layer, a packaging material layer and a back plate glass layer. The glass substrate layer ismade of a common glass material plated with a color layer or a color glass material plated with an antireflection film; the common glass is a piece of an ultra-clear float glass; the color glass is formed by adding a related coloring agent into the glass; and the color layer is formed by the color metal or metallic compound material based on processes of sputtering, vapor deposition, vapor deposition, silk-screen printing and the like. The prepared color cadmium-telluride thin-film solar cell has the diversified colors to meet the requirement of the appearance colors of buildings. Compared with the existing color crystalline silicon solar cell, the color cadmium-telluride thin-film solar cell has advantages of high flexibility, light weight, and optimized weak-light generation effect and is suitable for promotion and wide application.

Description

technical field [0001] The invention relates to a colored cadmium telluride thin-film solar cell and a preparation method thereof, belonging to the technical field of solar cells. Background technique [0002] Combining with buildings and grid-connected power generation is a form of new energy utilization in which photovoltaic systems are attached to buildings. It is the main market and important development direction of photovoltaic power generation in the future. Buildings, as the environment and urban landscape, have high requirements for appearance and color, so the appearance coordination of photovoltaic systems is also improved accordingly. At present, colored crystalline silicon solar cells are more researched, but crystalline silicon is the most expensive solar module, and crystalline silicon solar cells have disadvantages such as high cost, low solar absorption factor, brittle and fragile materials, and poor weak light effect.
