Thin film type semi-rigid solar cell array and manufacturing method thereof

Abstract

The invention discloses a thin film type semi-rigid solar cell array and a manufacturing method of the thin film type semi-rigid solar cell array. The cell array comprises a substrate, solar cell components, connecting sheets, cables in the substrate and a frame, the substrate is made of light thin film materials or thin plate materials, the solar cell components are arranged on the front face of the substrate, the connecting sheets are metal sheets laid on the front face of the substrate, one end of each cable in the substrate is wound around the edge of the substrate to be connected with the corresponding connecting sheet, the frame is made of light rigid materials, and the substrate is fixed to the frame. Due to the fact that the substrate of the semi-rigid solar cell array is made of the light thin film materials or thin plate materials, the connecting sheets and the cables in the substrate are all metal sheets laid on the substrate, and the frame is made of the light rigid materials, the thin film type semi-rigid solar cell array has the advantages of being light, small in thickness and high in strength. In addition, the solar cell components, the cables in the substrate and the connecting sheets can be automatically laid, and therefore production efficiency is high, and manufacturing is easy.

Description

[0001] technical field [0002] The invention relates to power supply technology in the aerospace field, in particular to a thin-film semi-rigid solar cell array and a manufacturing method thereof. Background technique [0003] Most of the spacecraft are powered by solar cell arrays. The electric energy generated by the solar cell strings on the solar cell array is transmitted to the interior of the spacecraft through cables for use by the spacecraft. At present, the most widely used is the rigid solar cell array. The solar cell array uses an aluminum honeycomb rigid substrate. Although the rigidity of the solar cell array is good, it has the disadvantage of heavy weight. [0004] In order to overcome this shortcoming, a semi-rigid solar cell array has been developed at home and abroad. This cell array is laid with a flexible glass fiber mesh on a rigid frame, and the solar cell modules are installed on the grid of the glass fiber mesh by hooking. , install components such ...
