Abstract

The invention relates to a universal easily-installed photovoltaic component and a photovoltaic mounting structure using the same. The photovoltaic component is composed of an OCA optical cement bonding layer, a lighted surface encapsulation layer, a first bonding layer, a photovoltaic cell layer, a second bonding layer and a back support layer through stacking in sequence from the top to bottom. The surface of the back support layer back on to the photovoltaic cell layer is provided with a back protection layer, and a release layer covers the surface of the OCA optical cement bonding layer. The universal easily-installed photovoltaic component is bonded to the back of a transparent rigid application component through the OCA optical cement bonding layer of the lighted surface. The universal easily-installed photovoltaic component has beneficial effects that the photovoltaic power generation manufacturing and the application product manufacturing are performed independently, the design cost of the photovoltaic application product is saved, the design period is shortened, and the mounting time and the mounting cost of the photovoltaic application product are saved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a general-purpose easy-to-install photovoltaic component and a photovoltaic installation structure using the component. Background technique [0002] In 1955, in order to verify the potential of photovoltaic technology to power communication systems, Bell Labs designed the first photovoltaic module. The photovoltaic module has a power of 10W, is sealed with silicone oil, and has a module efficiency of 2%. In 1958, silicon solar cells began to be used in space. The symbol of civil high-reliability components is BPX47A produced by Philips in 1976. Its structure is double-layer glass + silicon rubber, rubber edge seal, aluminum frame, and the electrode of the battery is Ti / Pd / Ag. The component efficiency is 6.4%. Since 2004, the photovoltaic industry has been vigorously promoted by the governments of various countries, especially Germany. [0003] Before 2013, the ...
