Abstract

The invention provides a photovoltaic glass and a photovoltaic power generation system, which relates to the technical field of power generation system. The photovoltaic module provided by the invention comprises a photovoltaic glass and a terminal box. The tempered glass film is covered on one side of the power generation layer which absorbs sunlight, and the back plate is bonded on the side of the power generation layer which is opposite to the tempered glass film. The junction box is connected with the power generation layer to alleviate the technical problem that the toughened glass of thefront plate in the photovoltaic module is easy to generate more light loss in the related art.

Description

technical field [0001] The invention relates to the technical field of power generation systems, in particular to a photovoltaic module and a photovoltaic power generation system. Background technique [0002] The current CIGS (solar thin film battery, English full name: CuInxGa (1－x) Se 2 ) Glass-based power generation chip packaging is mainly formed by bonding the battery chip to the tempered glass on the front plate by using PVB (polyvinyl butyral, English full name: Polyvinyl Butyral) film, and the junction box is connected to the component by opening holes on the battery chip. back or sides. [0003] The tempered glass on the front panel has poor surface flatness due to tempering treatment, which is prone to more light loss; the PVB film is easy to turn yellow, resulting in a significant decrease in the light transmittance of the glass, which affects the power generation efficiency of photovoltaic chips. Contents of the invention [0004] The purpose of the present...
