Embodiment Construction

[0025] Cooperate figure 1 , 2 Shown, the preparation method of a kind of flexible solar cell assembly of the present invention, its concrete steps are:

[0026] 1), first spread the polymer film 1; the polymer film is an ethylene-polytetrafluoroethylene (ETFE) protective film with good light transmission.

[0027] 2) Next, cut the cloth base 2 into required specifications and place it flat on the polymer film 1; the cloth is polyester, nylon, acrylic, vinylon, cotton, viscose, hemp, flax, ramie, silk or more fibers One of blended fabrics and non-woven fabrics.

[0028] 3), put the unit solar cell chip 3 into the cloth base 2, the cloth base 2 is the upper cloth base 21, and the part of the upper cloth base 21 corresponding to the light-receiving part of the unit solar cell chip 3 is cut out to leave the hole 211 for the purpose of After packaging, the light-receiving part of the unit solar cell chip 3 is not covered; use a laminator for low-temperature hot-pressing and fixi...

Abstract

A processing method of soft solar cell component and its specific steps include: 1) polymer film is evenly paved firstly; 2) cloth substrate is cut into needing size, and is pave on the polymer film; 3) solar cell chips are set into the cloth substrate, and are low-temperature-and-heat-pressure fixed by using laminating machine; 4) the chips are taken out then to carry welding and protection; 5) the fixed solar cell components are paved with their surface downward, and the cloth substrate is paved on the top; 6) using laminating machine, the solar cell components enter hot pressing step to be packed; 7) the components are taken out, and their margins are cut into tidy; 8) outlet line and bandage parts are processed. Through hot-pressing processing and clinging into soft carrier (like cloth substrate) or protective film, the solar cell can be arbitrarily bended and easy to carry. Being covered by ethylene-polytetrafluoroethylene (ETFE) protective film, the production has characters of high dirt resistance, anticorrosion, tensile resistance, collision resistance, heat resistance and insulation.

Description

technical field [0001] The invention relates to a solar cell, in particular to a method for preparing a flexible solar cell component. Background technique [0002] Solar photovoltaic power generation is the most promising way of new energy and renewable energy. The most basic components of solar photovoltaic power generation are solar cells, including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. A solar panel consisting of one or more solar cells is called a photovoltaic module, or solar cell module. Due to the economic advantages of amorphous silicon solar cells, its position in the entire solar cell field is rapidly rising, and it has become the focus of energy plans in some developed countries. [0003] Amorphous silicon solar cells are divided into two categories: hard substrate and flexible substrate. Amorphous silicon solar cells with flexible substrates, as a new type of amorphous silicon solar cells, have been paid ...
