Description
Technical field
The present invention relates to a kind of street lamp, especially relate to polymer Li-ion battery/DSSC wind and light complementary road lamp.
Background technology
Along with the growing tension of traditional energy resource and the enhancing of people's environmental consciousness, solar street light is because advantages such as its energy-saving and environmental protection are subjected to extensive attention both domestic and external.Solar street light captures solar energy daytime, and changes into electric energy and be stored in the battery, uses for night illumination.Use solar street light, can reduce electricity charge spending greatly with electric unit.Yet, be subjected to the restriction of actual battery electric power storage ability, add weather neglect sometimes fine neglect cloudy, overcast and rainy continuously sometimes, like this, solar street light will owing to acquisition less than enough solar energy, and forfeiture illumination functions.Adopt the associating lighting system of solar energy, wind energy complementary, can improve the unstability of illumination greatly, but wind-power electricity generation is subjected to the influence that wind is calm, the wind strong wind is little, if run into area, picture in February, 2009 Shanghai nearly one month wet weather and gentle breeze weather continuously, solar street light is owing to can not get the unstability that enough electric power can cause illumination too.A lot of solar street lights adopt general lighting electric power as stand-by power supply, this lays flourishing area at electrical network is the comparison material benefit, yet in meagrely-populated areas such as field, wilderness, mountain area, islands, the cost of cable laying is very high, iff being to be extremely non-remunerative in order to replenish the street lighting power shortage.Existing polysilicon solar cell technology but is faced with the significant challenge from cost of electricity-generating and " green " manufacturing mode two aspects.On the one hand, the cost of electricity-generating of crystal silicon solar energy battery is high, is traditional thermoelectricity, more than 5 times of water power cost, compares with conventional electric power, lacks competitiveness on price; On the other hand, pollution that the crystal silicon solar energy battery plate produces in manufacture process and energy consumption are suitable with natural gas or coal power generation, this make solar battery technology itself high pollution and the high energy consumption in the manufactured process of benefit brought to environment of the power generation process of intrinsic pollution-free, renewable, environmental protection offset.If do not solve expensive and " green " manufacturing issue, the extensive development and the Application Prospect of solar cell cause anxiety.Lead-acid accumulator, serious environment pollution, and the lead-acid accumulator electric power storage is limited in one's ability, and the life-span is short.The DSSC technology of Xing Qiing in recent years can effectively solve the drawback of polysilicon solar cell.
Dye-sensitized solar cells (DSSC) is that the research group by professor M.Graetzel of Lausanne, SUI higher technical school leader in 1991 utilizes the Nature photosynthesis principle, the third generation solar battery technology of invention.This technology has adopted and diverse structure of silion cell and photoelectricity transforming principle, and its cost of material and preparation technology's cost descend greatly, only be silion cell 1/10th or lower; And the manufacture craft that this technology adopts is simple relatively, energy consumption is low, pollution is little, and is environmentally friendly; In addition, dye-sensitized cell also has otherwise advantage, as less demanding to illumination condition, even if indoorly also can not use in that sunlight is overabundant; If with flexible base, board instead of glass such as plastics, metallic plates, promptly make flexible flexible battery; It is made display, then can generate electricity, and meanwhile luminous, realize that power self-support is self-sustaining.More than these characteristics make dye-sensitized solar cells show powerful commercial application value and potential competitiveness, become one of focus of technical field of solar batteries research.Its raw material are extremely abundant, technology is simple relatively, production cost is low, in large-scale industrialized production, have comparative advantage, and raw material and production technology all are nontoxic, free of contamination, and recyclable utilization again has important practical significance to energy-conserving and environment-protective.The photoelectricity dye-sensitized solar cells of DSSC (DSSC:Dye Sensitized Solar Cell) becomes one of main candidate of solar battery technology of new generation with characteristics such as its low cost, green manufacturing and high conversion efficiencies.Development in future concentrates on and how further improves conversion efficiency, reliability, but the integrated manufacture view of exploitation large tracts of land.
DSSC (DSSC) structure is mainly by electro-conductive glass (substrate of glass and nesa coating), Nano semiconductor membrane electrode, dye sensitizing agent, redox electrolytes matter, form several parts such as electrodes.The concrete generating operation principle of DSSC is: dye molecule absorbs behind the sunshine from the ground state transition to excitation state; The electronics of excitation state dyestuff is injected into rapidly in the conduction band of Nano semiconductor; Diffuse to conductive substrates subsequently; Be transferred to electrode through external loop, the dyestuff that is in oxidation state is reduced the electrolyte reducing/regenerating of attitude; The electrolyte of oxidation state is reduced in that electrode is accepted electronics, thereby has finished a cyclic process of electron transport.In these processes, be accompanied by two back of the body reactions: be injected into TiO
2The recombination reaction of the electron acceptor in the electronics in the conduction band and oxidation state dyestuff or the electrolyte.Compare with traditional pn joint solar cell, the maximum characteristics of DSSC are that transmission is to be finished by different materials respectively with separation of charge in its light absorption, light absorption is to finish by the dyestuff that is adsorbed on the Nano semiconductor surface, and the Nano semiconductor film plays electric charge to be separated and transport vehicle.But its technology of dye-sensitized cell itself remains in some critical technical problems and does not solve well, and mainly comprise: 1) photoelectric transformation efficiency of battery unit is low, and the highest conversion efficiency is about 11%, far below crystal silicon solar energy battery; 2) conversion efficiency of area battery unit significantly reduces, and the conversion efficiency of the large tracts of land DSSC of report all is lower than 8% in the world at present, is unfavorable for realizing scale of mass production; 3) performance of DSSC unit is stable not enough, and still there are bigger gap in the reliability of device and life-span apart from crystal silicon solar energy battery.Solve the approach of these key technical problems, need on the basis of basic research, optimize the structure and material of DSSC device on the one hand, comprise electrode, dyestuff, electrolyte and combination thereof; On the other hand, need to optimize assembling, encapsulation and the integrated manufacturing technology of DSSC unit and module.The low cost that the DSSC technology is had, low energy consumption, the low pollution, environmentally friendly, and characteristics such as have wide range of applications, make it show powerful commercial application value and potential competitiveness.
Relative other type cell, polymer Li-ion battery, specific energy height, pollution-free, safe, memoryless property, life-span length, shape can be changed arbitrarily, are that the ideal of battery is selected.DSSC, polymer Li-ion battery are used for Solar energy and wind energy street lamp, have both realized the purpose of environmental protection, again for street lamp provides continued power, reach illuminating effect steady in a long-term.
