High-output-voltage flexible thin film solar cell module for near space aircraft

Abstract

The invention relates to a high-output-voltage flexible thin film solar cell module for a near space aircraft, which comprises a plurality of solar cell strings, an isolation diode module, a fixed transparent insulating adhesive tape, a flexible interconnection transverse strip and a leading-out welding strip, wherein the plurality of solar cell strings are arranged on the fixed transparent insulating adhesive tape; the isolation diode modules are pasted on the leading-out silver foils at the tail ends of the solar cell strings, and the adjacent solar cell strings are connected in series through the flexible interconnection transverse strip and output in parallel through the leading-out welding strip. The solar cell module has the following beneficial effects that in a laying area with small rib spacing, the output voltage of a single solar cell module can reach more than 100 V, and the application advantage is expanded; high-voltage output is formed without connecting multiple assemblies in series, so that the design difficulty of the high-output-voltage curved-surface laid solar cell array is reduced; and the maximum voltage difference between the adjacent solar cell strings is within 80V, so that the electrostatic protection requirement is met, and the safety and reliability of the solar cell array are improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a high-output-voltage flexible thin-film solar cell assembly for a near space vehicle. Background technique [0002] Flexible thin-film solar cell modules have the characteristics of light weight, high flexibility, and high efficiency, and have been widely used in near-space solar unmanned aerial vehicles. In general, in order to increase the speed of the motor during high-altitude flight, the output voltage of the solar cell array is generally required to reach above 100V. However, the output voltage of solar cell modules designed in the past is generally between 50-80V, which is difficult to meet the needs of use and greatly reduces the power of the aircraft. [0003] The main reasons why high output voltage cannot be achieved at this stage are as follows: [0004] (1) Limited by the structural strength of solar unmanned aerial vehicles, the ...
