Flexible solar cell module hot pressing device

Abstract

The invention relates to a hot pressing device for a flexible solar battery component, and solves the defect that due to long-term heating at high temperature, gases produced in a solar battery component are difficult to discharge, and bubbles are produced on the outer surface of the solar battery component to affect product appearance, the hot pressing device comprises an upper component and a lower component, a heating system, a vacuumizing system and a control system, the upper component and the lower component can be mutually laminated to form a closed shaped hot pressing cavity used for lamination of a non flat or curved flexible solar battery component, the heating system is used to provide heating temperature for hot pressing of the solar battery component, the vacuumizing system is used for vacuumizing the upper component and the lower component and overall floating the solar battery component for hot pressing, and the control systemis used for controlling the heating system and the vacuumizing system. The heating system is used for heating the hot pressing cavity, the vacuumizing system is used for vacuumizing the upper component and the lower component, the solar battery component floats in the hot pressing cavity, only after the solar battery component completely enters the hot pressing cavity and up floats, the hot pressing is performed, the lamination degree of the whole piece of the solar battery component can be ensured, and quality is stable.

Description

technical field [0001] The invention relates to the field of flexible solar cell production, in particular to a flexible solar cell module hot-pressing device. Background technique [0002] As a new type of solar cell, thin-film solar cells have broad market prospects due to their wide source of raw materials, low production costs, and ease of mass production. Amorphous silicon thin-film solar cell components try to use the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. [0003] The performance requirements of thin-film solar cell components are low power attenuation, long working life, and sufficient mechanical strength. Since the power generation layer and conductive layer film are exposed to the air, they are easily affected by chemical oxidation, physical aging, and water vapor erosion. It poses a fatal threat to the output power, working life and mechanical strength of the module, so it needs to be protected ...
