Problems solved by technology

The current bending test device bends through three or four stress points, which is inconsistent with the actual working conditions of the flexible thin film solar cell, and has many defects, such as the edge damage of the flexible thin film solar cell caused by the clamping device, and the minimum bending radius obtained by the test deviates. Large, the force situation does not match the actual situation, etc.

Abstract

The invention discloses a testing device for a bending test of a flexible thin film solar cell, and belongs to the technical field of flexible solar cells. The fixed supporting rod is fixed on the two linear guide rails; the sliding support rod is arranged on the two linear guide rails; the power mechanism drives the sliding support rod to move along the two linear guide rails; the flexible thin film bearing platform is used for bearing the flexible thin film solar cell; the flexible film bearing platform is fixedly connected with the sliding supporting rod and the fixed supporting rod. And a temporary adhesive is arranged on the upper surface of the flexible film bearing platform. The flexible thin film solar cell is fixed through the guide rail and the flexible thin film bearing platform, and the flexible thin film bearing platform is pushed to move back and forth accurately through the stepping motor, so that the bending test of the flexible thin film solar cell is realized. The preparation process is simple, the cost is low, the actual working condition of the flexible thin film solar cell is better matched when the bending test is carried out, and the bending characteristic of the flexible thin film solar cell can be more accurately assessed.

Description

technical field [0001] The invention belongs to the technical field of flexible solar cells, and in particular relates to a bending test device for flexible thin-film solar cells. Background technique [0002] There is an urgent need for flexible solar cells in aerospace research, military weaponry, and civilian markets. Compared with rigid solar cells, flexible solar cells have the advantages of cheap substrate materials, abundant substrate materials, light weight, high power-to-weight ratio, flexibility and bendability, and good surface coverage. [0003] In order to ensure the reliability of flexible thin-film battery products, it is necessary to evaluate its bending characteristics to ensure that the appearance of the battery is not damaged after repeated bending, and the electrical performance has no obvious decline. The evaluation of the bending characteristics of flexible thin film batteries is usually carried out by fixing the battery on the bending test device. Th...
