Abstract

The invention relates to a solar battery component which is formed by sequentially superposing a surface packaging film, a transparent glue film, a solar battery plate, a lightweight glue film, an insulating substrate, a lightweight glue film, a solar battery plate, a transparent glue film and a surface packaging film from top to bottom in close contact without interlayer clearances, wherein the insulating substrate is formed by sequentially superposing an insulating film, a carbon fiber plate, a lightweight glue film, a honeycomb core, a lightweight glue film, a carbon fiber plate and an insulating film from top to bottom in close contact without interlayer clearances; to ensure that the battery component can be connected with related structures, an embedded part is arranged in the honeycomb core; and the specific position of the embedded part is determined by the connecting mode. The double-sided solar battery component has the advantages of light weight, high efficiency and good low-temperature property, makes the most of the solar energy in a limited area, is very suitable for the requirement of long-term regional residency of an aerostat in the stratosphere, and has application value in the technical field of solar photovoltaics.

Description

1. Technical field: [0001] The invention relates to a double-sided solar battery assembly, which belongs to the technical field of solar photovoltaics. 2. Background technology: [0002] Previous solar cell components were mainly used in space or on the ground, and cell components designed for the working environment of stratospheric aircraft, especially double-sided cell components, have not yet appeared. With the further expansion of the field of aerospace technology, the stratospheric aircraft used in the joint of aviation and spaceflight has become the focus of research in various countries. Among these aircraft, the stratospheric aerostat has attracted the most attention. Equipped with a solar cell array and a recyclable energy storage system, the stratospheric aerostat has the advantages of high flight altitude, long service life, regional residence, and low environmental pollution. It can be used for communication relay, early warning, detection and monitoring, High-...
