The invention discloses a semi-rigid solar cell module structure and a preparation method thereof. The module structure comprises a solar cell, an interconnecting sheet, a module connecting sheet, a diode and a glass cover sheet. The glass cover sheet comprises an upper glass cover sheet and a lower glass cover sheet. The lower glass cover sheet is of an abnormal structure. The upper glass cover sheet is of the same structure as the solar cell, and the solar cell is enclosed between the upper glass cover sheet and the lower glass cover sheet. The solar cell, the diode and the module connectingpiece are connected through the interconnecting piece. The solar cell module provided by the invention has the advantages of high integration, reliable structure, small mechanical response of the solar cell module, and the diode does not occupy the power generation area of the solar cell, thus improving the space power generation capacity of the solar cell array and improving the space application capacity of the solar cell array.
Description
technical field [0001] The invention relates to the technical field of space solar battery arrays, in particular to a method for designing a semi-rigid solar battery circuit for spacecraft. Background technique [0002] A solar cell is a semiconductor device that uses the photovoltaic effect to directly convert light energy into electrical energy. A power supply system composed of solar cell circuits can provide energy for spacecraft, and semi-rigid solar cell circuits are one of them. The semi-rigid solar cell module is different from the flexible solar cell array and the semi-rigid solar cell array. The module itself is double-sided sealed with a glass cover, and the module and the substrate or substrate are connected together through the glass cover. However, the solar cell and the bypass diode are connected in the same way. Usually, the bypass diode is placed at the corner of the solar cell, and the solar cell and the bypass diode are integrated through the interconnect...
