Background technology
Along with the development of human civilization, the whole world faces the problems such as serious energy crisis and environmental pollution.Wherein, using solar energy directly can be transformed into electric energy photovoltaic solar cell as solving whole world energy crisis and reducing one of important method of environmental pollution.The module that solar cell forms is exposed to the sun conventionally in the sun, for fear of shining upon the temperature that affects battery module, and then affects the generating efficiency of battery module, therefore, particularly requires solar cell backboard to have good heat dispersion.
In actual applications, solar cell is to be generally together in series or parallel by polylith battery component, to obtain desired voltage or electric current.In order to reach higher photoelectric conversion efficiency, each the piece cell piece in battery component all must have similar characteristic.In use, may occur that one or a Battery pack do not mate, as: there is the situations such as crackle, inner Joint failure or shading, cause its characteristic and not harmony of integral body.Under rational illumination condition, the photovoltaic cell of crested in a series arm, can become power consumption unit from generator unit, the photovoltaic cell of crested is not only to not contribution of assembly output, and can consume the electric power that other battery produces, and now can generate heat, Here it is hot spot effect.
The main method that solves at present hot spot effect has following several:
One, be a diode in parallel on solar module.Generally, this diode does not affect assembly and normally works.When the battery in assembly is blocked, now diode current flow, crosses cause thermal damage thereby avoid being hidden battery.
Two, adopt inorganic superconducting hot pipe technique.The heat transfer medium combining with multiple inorganic elements, joins in tube chamber or double wall chamber, after vacuum treatment and sealing, forms the element with efficient heat transfer characteristic.In the process that this element is conducted heat to the other end fast by one end, surface presents without the quick wavy thermal conduction characteristic of thermal resistance.It both can guarantee the photoelectric conversion efficiency of condensation photovoltaic lithium battery, can obtain again appreciable photo-thermal income simultaneously, realized the electrothermal combined using to solar energy, to meet domestic consumer's daily life electricity consumption and hot water.
Three, the operation principle of solar panel is, after utilizing photoelectric material to absorb luminous energy, opto-electronic conversion reaction occurs.Photoelectric conversion rate is higher, and solar panel energy output is larger, and improving photoelectric conversion rate is to reduce photovoltaic cost main cause.Solar cell can be electric energy by the transform light energy of visible ray, and ultrared frequency ratio visible ray more approaches the natural frequency of solid matter, therefore more easily cause the resonance of molecule, infrared ray more easily becomes the interior energy of material, causes that the temperature of solar panel plate body raises.Stoping so infrared ray is the key that reduces the temperature of solar panel plate to the irradiation of solar panel plate body.What conventionally adopt is clear glass, and clear glass can the overwhelming majority see through visible ray, and the infrared ray that can stop sunlight not change, and then can reduce the temperature of solar panel plate body, improves the photoelectric conversion rate of solar cell.
