Abstract

The invention relates to a W-shaped arrangement integrated photovoltaic power generating waterproof roll and a preparation method thereof . The photovoltaic power generating waterproof roll comprises,from top to bottom, at least photovoltaic power generating layers and waterproof layers, which are in a W-shaped arrangement; and glass protection layers, which are provided according to conditions.The abovementioned layers are bonded together in a fixed manner. The photovoltaic cell panels are innovatively disposed on surfaces of W-shaped stamping metal sheet having good mirror effect, and thenoccupied area is greatly reduced, and an optical trap is easily formed between two inclined photovoltaic metal sheets, and then more light irradiation can be received, and therefore photovoltaic conversion efficiency can be improved, and in addition, influences of illumination angles are reduced, and a plurality of cavities are formed in the bottom part to stop heat transfer, and therefore good thermal insulation effect is provided, and the provided photovoltaic power generating waterproof roll has advantages of long service lifetime, low costs, and wide application range.

Description

technical field [0001] The invention relates to the technical field of photovoltaics, in particular to a W-shaped arrangement integrated photovoltaic power generation waterproofing membrane and a preparation method thereof. Background technique [0002] At present, there are many kinds of photovoltaic power generation products on the market with broad application prospects, but the common technical bottleneck of low photoelectric conversion efficiency has always restricted the development of photovoltaic industry. [0003] The invention breaks the plane laying method of the traditional photovoltaic power generation waterproof membrane, and innovatively adopts the W-shaped three-dimensional laying form, which not only greatly saves the floor space, but also has more advantages: firstly, the photoelectric conversion efficiency is improved, Photovoltaic cells are laid in the grooves of the W-shaped plate, and light irradiated in the V sub-structure will repeatedly irradiate lig...
