Problems solved by technology

[0002] In recent years, under the vigorous advocacy of new energy concepts, solar photovoltaic devices have gradually been promoted around the world. Polycrystalline silicon solar modules have a certain share in the market due to their reasonable price and good performance. Similar to photovoltaic modules, polysilicon modules will produce more or less power attenuation during use, which will affect their service life
[0003] The attenuation of polysilicon cell components is mainly due to the vibration of the components during handling and installation, and even the violent impact of hail during use, which leads to internal cracks in the components, followed by the aging and attenuation of the components after being exposed to ultraviolet radiation.

Abstract

The invention discloses a polycrystalline silicon battery pack. The polycrystalline silicon battery pack is formed by sequentially stacking first tempered glass, a first glue film, a polycrystalline silicon battery string, a second glue film, a reflecting plate, a third glue film and second tempered glass from top to bottom through a lamination technology, a nanometer titania film layer is arranged on the upper surface of the first tempered glass in a thermocompression bonding mode, a uvioresistant coating is arranged on the lower surface of the first tempered glass in a thermocompression bonding mode, and an elastic rubber layer is arranged on the upper surface of the second tempered glass in a thermocompression bonding mode. In this way, the polycrystalline silicon battery pack has good strength, ultraviolet light resisting performance and vibration resisting performance, the attenuation phenomenon can be effectively delayed, and the service life is long.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation equipment, in particular to a polycrystalline silicon cell assembly. Background technique [0002] In recent years, under the vigorous advocacy of new energy concepts, solar photovoltaic devices have gradually been promoted around the world. Polycrystalline silicon solar modules have a certain share in the market due to their reasonable price and good performance. Similar to photovoltaic modules, polysilicon modules will produce more or less power attenuation during use, which will affect their service life. [0003] The attenuation of polysilicon cell components is mainly due to the vibration of the components during handling and installation, and even the violent impact of hail in the process of use, resulting in internal cracks in the components, followed by the aging and attenuation of the components after being exposed to ultraviolet radiation.
