Method for manufacturing transparent thin-film solar cell component

Abstract

The invention discloses a method for manufacturing a transparent thin-film solar cell component. The method comprises a process of manufacturing a transparent substrate, a first electrode layer, a photoelectric translating cell area and a back electrode layer and is characterized in that the back electrode layer is made from a high-permeability and high-conductivity transparent conducting film, wherein the conducting film consists of a first layer of transparent conducting sull, a metal film and a second layer of transparent conducting sull, which are sequentially deposited on the photoelectric translating cell area. The thickness of the metal film is only 5 to 30nm, so the metal film has good light transmittance. Compared with the prior art, the method has the advantages of simple manufacturing process, low cost of raw materials and good light transmittance, is suitable for mass production and has very wide market prospect.

Description

technical field [0001] The invention relates to a method for manufacturing a thin-film solar cell assembly, in particular to a method for manufacturing a light-transmitting thin-film solar cell assembly that can be used as photovoltaic building integration and agricultural greenhouses. Background technique [0002] At present, thin-film solar cells usually use a thicker metal layer as the back contact electrode. Due to the high reflection of the metal layer, the light that is not absorbed by the photoelectric conversion cell area can be incident on the layer again, thereby improving the efficiency of the solar cell. However, the cells with this structure are opaque to light and cannot be used as the roof of building integrated photovoltaics and agricultural greenhouses. At present, there are related technical reports on light-transmitting thin-film solar cells. The structure generally includes a transparent substrate, a transparent conductive layer, a back electrode, and a p...

However, the cells of this structure are opaque to light and cannot be used as the roof of photovoltaic building integration and agricultural greenhouses

At present, there are related technical reports on light-transmitting thin-film solar cells. The structure generally includes a transparent substrate, a transparent conductive layer, a back electrode, and a photoelectric conversion cell area between the transparent conductive layer and the back electrode. The back electrode is made of Metal film, the thickness of the metal film is generally 100-250nm. The metal film of this thickness completely blocks light. To achieve the effect of light transmission, part of the back electrode needs to be removed by laser cutting, but this method is only used in On the basis of a thicker metal back electrode, an additional process is added to remove part of the metal layer. On the one hand, this kind of production method complicates the preparation process, and on the other hand, it causes waste of raw materials.
