Abstract
The utility model relates to the field of solar energy photovoltaic photo-thermal technology and provides a novel photovoltaic photo-thermal module. The novel photovoltaic photo-thermal module includes a solar cell array. One side of the solar cell array is provided with a tempered glass board while the other side of the solar cell array is provided with a back board. EVA cushion layers are arranged between the solar cell array and the tempered glass board and between the solar cell array and the back board in a bonded manner. The solar cell array includes a plurality of solar cells connected with each other successively through solder strips and arranged in an array. Gaps are arranged between each two adjacent solar battery cells. The back board is transparent. A blue film heat collecting board is bonded on the lower side of the transparent back board. The blue film heat collecting board includes a heat collecting board core and a blue film clad layer plating on the upper surface of the heat collecting board core. Working temperature of the solar cell array can be reduced effectively, so that the solar cell array can be kept in a stable working state. Solar energy photoelectric converting efficiency is improved and photo-thermal converting efficiency of solar energy can also be improved. Therefore, comprehensive utilization efficiency of the solar energy can be improved.
Description
Technical field
The utility model relates to photovoltaic and photothermal solar technical field, relates in particular to a kind of Novel photovoltaic photo-thermal module.
Background technology
Solar energy is a kind of clean, economic, stable energy.The solar energy resources of China is relatively abundant, and photovoltaic generation and solar water heater industry have formed industrialization production through fast development in a few years, and technology is constantly brought forth new ideas, and properties of product are are constantly improved and optimizated, and are widely used at present.In photovoltaic generation process, solar energy utilization ratio only has tens percent, and large energy is absorbed and is converted to heat energy by battery, if these energy are reclaimed, can greatly improve the utilance of solar energy.
For dull and stereotyped crystal silicon solar batteries, the temperature coefficient of operating voltage (Vmp) is about-0.0045/ DEG C; The temperature coefficient of open circuit voltage (Voc) is about-0.0034/ DEG C.In photovoltaic generation process, along with solar cell junction temperature, temperature rise declines solar cell open circuit voltage Voc, and short circuit current Isc slightly increases, and total cognition causes the power output of solar cell to decline.
For amorphous silicon film battery, the temperature coefficient of operating voltage (Vmp) is about-0.0028/ DEG C (coefficient of amounting to 70 DEG C is 0.874); The temperature coefficient of open circuit voltage Voc is about-0.0028/ DEG C (coefficient while amounting to-10 DEG C is 1.1).
For solar cell temperature, rising can cause the problem that the power output of solar cell declines, and is an important problem to opto-electronics.
Utility model content
The purpose of this utility model is to provide a kind of Novel photovoltaic photo-thermal module, when being intended to improve solar photovoltaic conversion efficiency, improves the photo-thermal transformation efficiency of solar energy, thereby improves the comprehensive utilization ratio of solar energy.
The utility model is to realize like this, Novel photovoltaic photo-thermal module comprises solar cell chip arrays, one side of described solar cell chip arrays is provided with armorplate glass, opposite side is provided with backboard, between described solar cell chip arrays and described armorplate glass and between described backboard, be all bonded with EVA bed course, described solar cell chip arrays comprises and is multiplely connected and is the solar battery sheet of arranged in arrays by welding successively, between every two adjacent described solar battery sheets, is equipped with gap; Described backboard is transparent back panel; Below described transparent back panel, be bonded with blue film collecting plate, described blue film collecting plate comprises heat-collecting plate core and plates the blue film coating of being located at described heat-collecting plate core upper surface.
As a kind of improved plan, the distribution proportion between described solar battery sheet and described gap is horizontal 1:1～1:2, longitudinally 1:0.5～1.5.
As a kind of improved plan, the distribution proportion between described solar battery sheet and described gap is horizontal 1:1.5, longitudinally 1:1.
As a kind of improved plan, described heat-collecting plate core is aluminium alloy heat-collecting plate core.
As a kind of improved plan, between described transparent back panel and described blue film collecting plate, be bonded together by heat-conducting glue.
As a kind of improved plan, described heat-collecting plate core comprises parallel many heat pipes that arrange, the water inlet of many described heat pipes is communicated with water inlet pipe jointly, the delivery port of many described heat pipes is communicated with outlet pipe jointly, described heat pipe is fixedly connected with upper cover plate near a side of described blue film collecting plate, and described heat pipe is fixedly connected with lower cover away from a side of described blue film collecting plate.
As a kind of improved plan, be covered with heat-insulation layer below described blue film collecting plate.
The photovoltaic and photothermal thermal-arrest module that the utility model provides, because it is all provided with gap between two adjacent solar battery sheets, promote the heat-sinking capability of solar battery sheet, and use transparent back panel, can not only improve the light permeable rate of sunlight, also can transmit efficiently solar panel and carry out the heat producing in photoelectric conversion process; And the blue film collecting plate that transparent back panel bonds below, can absorb fast and efficiently the heat that the solar battery sheet of transparent back panel transmission produces in photoelectric conversion process and the sunlight direct projection photo-thermal that sees through the gap between solar panel, and carry out rapidly photo-thermal conversion, then by heat-collecting plate core, the heat of its absorption and conversion is passed, and recycled by people.
The Novel photovoltaic photo-thermal module that the utility model provides, reduces the working temperature of solar cell chip arrays effectively, makes it in stable operating state, improves electricity conversion; And utilize blue film heat-collecting plate core to absorb by the heat of solar battery sheet generation and through the sunlight direct light thermal transition in the gap between solar panel, also solve the restriction because of space, implement photovoltaic generating system, and cannot implement photo-thermal system, cause the phenomenon that solar energy utilization ratio is low, improved greatly the utilance of luminous energy.Especially using roof type or wall-body photovoltaic generating system, and the area of demand hot water or engineering, can be extensively practical, be suitable for batch production.
