Solar cell module and preparation method thereof

Abstract

The invention provides a solar module which is composed of a surface sealing film, a transparent adhesive film, a solar cell, a lightweight adhesive film A and an isolated substrate which are stacked from the top to the bottom in order; and the isolated substrate is composed of an isolated film, a carbon-fiber sheet, a lightweight adhesive film B, a honeycomb core, a lightweight adhesive film C and the carbon-fiber sheet which are stacked from the top to the bottom in order, wherein the honeycomb core inside also needs to be appropriately added embedded parts according to concrete operating requirements. The technical scheme of a preparation method of the solar module comprises following steps: (1) making use of an oven to match with a vacuum air pump to process a pre-compacting treatment for a carbon-fiber prepreg; (2) meanwhile, processing a welding sequence of the solar cell; (3) processing a cutting sequence; (4) processing a laminating technology treatment; (5) processing post treatment procedures which in order are: removing raw edges, embedding strakes, arranging a junction box, measuring high voltage, cleaning the surface, measuring photo-electrical output characteristics, classifying components, and examining the appearance. The solar module has the advantages of lightweight, high efficiency and good low-temperature characteristics, and being very suitable to being applied in the stratosphere.

Description

1. Technical field: [0001] The invention provides a solar battery component and a preparation method thereof, belonging 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 the cell components designed for the working environment of stratospheric aircraft 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-altitude technology ver...
