Abstract
The invention discloses a CdTe thin-film solar cell system based on stone outer walls. The system comprises stone outer wall panels and is characterized in that the outer surfaces of the stone outer wall panels are covered with CdTe thin-film solar cells, and viscose layers are used for coating the place between the CdTe thin-film solar cells and the outer surfaces of the stone outer wall panels. The system is reasonable in whole designed structure and ingenious in conception, the CdTe thin-film solar cells are combined with the insulation stones into a whole, and a new-energy environment-friendly stone is formed and can be used singly or assembled into an outer wall vertical plane of a building. The CdTe thin-film solar cells has a high light absorption rate, the absorption coefficient reaches 104 cm <-1> or higher within the visible light range, and 95% of photons can be absorbed in an absorbing layer with the thickness of 1 mu m. Besides, during actual application, light energy conversion is achieved by the outer wall of a huge building, indoor temperature of the building is effectively reduced in midsummer, and energy conservation and environmental protection are realized; and the CdTe thin-film solar cell system based on the stone outer walls has a good practical effect and is easy to popularize and apply.
Description
Technical field
The present invention relates to the technical field that photovoltaic is used, specifically a kind of CdTe thin-film solar cell system based on stone outer wall, the particularly syndeton of stone outer wall and CdTe thin-film solar cells.
Background technology
Cadmium telluride (CdTe) thin-film solar cells is a kind of heterogeneous thin-film solar cells of becoming the basis with p-type CdTe and N-shaped Cd.
CdTe has that light absorpting ability is strong, and power generation stabilization is good, transformation efficiency is high, long, the many advantages such as generated energy is high and the energy recovery cycle is short of generating dutation on daytime, and its performance is better than and traditional crystal silicon solar batteries.
The CdTe thin film solar cell, domesticize at present, have that cost of production is low, low light level performance is good, photoelectric transformation efficiency occupies (high-photoelectric transformation efficiency has reached 15.5%～17.3%) first of the various thin-film solar cells, near crystal-silicon solar cell, cost then is 1/3rd of crystal silicon cell.
Greatly develop the solar energy cause and be the 21 century new forms of energy developing goal advocated to countries in the world of the United Nations, the central government has also formulated Chinese solar energy development plan for this reason.How the building stone exterior wall reaches the effect that produces the renewable energy resource, is the important topic that Ornamental Stone Industry is probed into always.
As everyone knows, building masonry wall has huge surface area, utilize if can be good at, so that it becomes the carrier of light energy conversion, just can greatly reduce whole energy consumption of building, just can reduce the bed rearrangement city in the same way, especially high as this class city development degree of Shanghai, Guangzhou, relatively sufficient region of duration of sunshine is particularly suitable.
Summary of the invention
The object of the present invention is to provide a kind of CdTe thin-film solar cell system based on stone outer wall, it is bonded to one stone outer wall panel and CdTe thin-film solar cells by structure glue, so that traditional masonry work exterior wall has the function that produces green energy resource, overcome the defective of Bartlit function singleness.
To achieve these goals, technical scheme of the present invention is: a kind of CdTe thin-film solar cell system based on stone outer wall, it comprises the stone outer wall panel, it is characterized in that: described stone outer wall panel outer surface is covered with the CdTe thin-film solar cells, is covered with adhesive-layer between CdTe thin-film solar cells and the stone outer wall panel outer surface.
The art of this patent discloses a kind of CdTe thin-film solar cell system based on stone outer wall, the whole project organization of this system is reasonable, be skillfully constructed, CdTe thin-film solar cells and insulation building stones are combined into one, form a kind of new forms of energy environment friendly stone, but the monomer use also can be assembled into the skin facade.The CdTe thin-film solar cells has high absorptivity, its absorption coefficient is more than visible-range is up to 104cm-1,95% photon can be absorbed in the thick absorbed layer of 1 μ m, invention is to use domestic CdTe thin-film solar cells, its conversion ratio is higher than international like product (routine U.S. CIGS thin-film solar cells conversion ratio only is 11%), and its cost is less than 1/3rd of international like product.
The present invention is the major reform to the building stone exterior wall, makes traditional stone outer wall, has incorporated the main effect that produces green energy resource, and present technique can be applicable to arbitrarily external wall, the roof space, makes Modern New external wall functionalization, energy-saving.
In actual applications, the art of this patent utilizes mega structure beyond the region of objective existence wall to realize transform light energy, and the time in midsummer is effectively reduced the Indoor environment temperature, realizes energy-conserving and environment-protective.The art of this patent has good practical function, is easy to promote quote.
