Abstract

The invention discloses a flexible substrate CdTe thin-film solar cell and a preparing method thereof. The flexible substrate CdTe thin-film solar cell is composed of the following seven parts including a transparent flexible substrate thin-film material layer, a transparent conducting thin film layer, a negative electrode, a CdS thin-film window layer, a CdTe thin-film absorbing layer, a back electrode metal contact layer and a flexible thin-film material packaging layer, wherein the transparent conducting thin film layer is formed in the manner that ZnxCd1-xO deposits on the flexible substrate thin-film material layer, the negative electrode is formed on the transparent conducting thin film layer, the CdS thin-film window layer is arranged on the transparent conducting thin film layer, the CdTe thin-film absorbing layer is arranged on the CdS thin-film window layer, the back electrode metal contact layer is arranged on the CdTe thin-film absorbing layer, and the flexible thin-film material packaging layer is arranged on the back electrode metal contact layer. The flexible substrate CdTe thin-film solar cell has the advantages of being low in cost, high in efficiency and capable of meeting requirements of different fields, and the preparing method can be applied to mass preparing of low-temperature technology flexible substrate CdTe thin-film solar cells.

Description

technical field [0001] The invention relates to the technical field of nano inorganic compound energy material manufacturing technology, in particular to a flexible substrate CdTe (cadmium telluride) thin film solar cell and a preparation method thereof. Background technique [0002] As a clean, pollution-free, inexhaustible natural energy source, solar energy has been paid more and more attention by people. Solar cells can directly convert solar energy into electrical energy, which has great advantages in the direct utilization of solar energy. People's research on solar cells can be divided into bulk solar cells and thin-film solar cells. Bulk solar cells refer to solar cells prepared on the basis of single crystal and polycrystalline ingot slices of compound semiconductors. Its Achilles' heel is large material consumption, complicated preparation process and high production cost. Therefore, people are more inclined to research on thin-film solar cells. [0003] Among ...
