Rigid-flexible integrated solar cell considering heat insulation and development method thereof

Abstract

The invention provides a rigid-flexible integrated solar cell considering heat insulation and a development method thereof. According to the method, a high-efficiency rigid solar cell serves as a basis, flexible modular package is carried out on the rigid solar cell through reasonable reference and improvement of a flexible thin film solar cell package technology and by a dual-layer film material matched with a glue film, and a rigid-flexible integrated solar cell module is formed; and a hollow flexible heat insulation material serves as a heat insulation layer and is mainly used for effective control on temperature difference between the upper surface and the lower surface of a substrate structure. With the rigid-flexible integrated solar cell considering heat insulation, developed on the basis of the method, the problem of effective combination of a rigid solar cell array and an airplane sectional curved surface can be effectively solved; since the rigid-flexible integrated solar cell considers heat insulation, a favorable working temperature environment can be provided for an onboard device; the comprehensive requirements of a solar unmanned aerial vehicle on two aspects of battery conversion efficiency and unit area battery specific power can be met; and the flight performance of the solar unmanned aerial vehicle is improved.

Description

1. Technical field: [0001] The invention provides a rigid-flexible integrated solar cell with thermal insulation and a development method thereof, belonging to the technical field of aerospace vehicle energy systems. 2. Background technology: [0002] High-altitude long-endurance UAVs, as unmanned aerial vehicles that can operate at altitudes above the stratosphere, can perform intelligence, surveillance and reconnaissance, communication relay, target indication, damage assessment, telecommunication and television services, atmospheric environment monitoring and weather Forecasting and other military and civil tasks have become the hotspot of today's research. [0003] On the other hand, the use of solar energy as the auxiliary energy and even the main energy of future aircraft is an important research goal with direction and frontier for human development. Solar-powered airplanes appeared in the 1970s with the reduction of the cost of solar cells. Since solar-powered airpl...

Problems solved by technology

For the application of high-efficiency solar cell arrays, rigid solar cells are currently the first to be used. The main applications are gallium arsenide solar cells and monocrystalline silicon solar cells. , the problem of rational combination of rigid battery array plane and airfoil surface has not been effectively solved so far

In addition, the temperature difference between the surface and the back of the solar cell on the high-altitude solar drone is small (0.5-2°C), and the internal temperature environment of the solar drone limits the use of airborne equipment
