In practical application, the external wall of a huge building can be utilized to convert luminous energy, the indoor temperature of the building can be effectively decreased in summer, energy can be saved, and the environment can be protected. The patented technology has a good practical effect, and is easy to popularize and apply.
Description
Technical field
The utility model relates to the technical field of photovoltaic application, 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 ofly with p-type CdTe and N-shaped Cd heterogeneous, to become basic thin-film solar cells.
It is strong that CdTe has light absorpting ability, 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.
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 various thin-film solar cells, approach crystal-silicon solar cell, cost is 1/3rd of crystal silicon cell.
Greatly develop 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 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, if can be good at, utilize, make it become the carrier of light energy conversion, just can greatly reduce whole energy consumption of building, in the same way just can reduce bed rearrangement city, especially high as Shanghai, Zhe Lei city, Guangzhou development degree, relatively sufficient region of duration of sunshine is particularly applicable.
Utility model content
The purpose of this utility model 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, make traditional masonry work exterior wall there is the function that produces green energy resource, overcome the defect of Bartlit function singleness.
To achieve these goals, the technical solution of the utility model is: a kind of CdTe thin-film solar cell system based on stone outer wall, it comprises stone outer wall panel, it is characterized in that: described stone outer wall panel outer surface is covered with CdTe thin-film solar cells, between CdTe thin-film solar cells and stone outer wall panel outer surface, be covered with adhesive-layer.
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, can monomer use also can be assembled into skin facade.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, utility model 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 is only 11%), and its cost is less than 1/3rd of international like product.
The utility model is the major reform to 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 external wall, the roof space arbitrarily, 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 Indoor environment temperature, realizes energy-conserving and environment-protective.The art of this patent has good practical function, is easy to promote quote.
