Description
Technical field
The utility model relates to a kind of solar powered Lawn lamp, particularly the Lawn lamp of powering about a kind of dye-sensitized film solar cell.Belong to field of illuminating lamps, also belong to new energy field.
Background technology
What existing solar lawn lamp generally adopted is that silicon is solar cell, comprise photovoltaic cells such as monocrystalline silicon, polysilicon and non-crystalline silicon, be positioned over Lawn lamp lampshade top, lead is connected to the rechargeable battery in the lampshade, and the control by switch and light sensitive diode makes Light-Emitting Diode or LED etc. at noctilucence.There is following problem in these Lawn lamps: 1, silicon is that solar cell is subjected to production cost and complicated preparation technology's check prince higher, has improved the cost of solar lawn lamp.2, be subjected to the intensity of illumination conditionality more, the strong inadequately or rainy weather of the sun just can not generate electricity, and Lawn lamp charges limited.3, to be that solar cell is opaque for silicon, is positioned at the Lawn lamp top, reduced by a Lawn lamp light-emitting area.4, to be that solar cell is black-and-blue for silicon, and color is left with no alternative, and aesthetics is not enough.
The most attracting characteristics of dye-sensitized solar cells (Dye-sensitized Solar Cell is called for short DSSC) are its cheap raw material and relative simple manufacture craft, and stable performance, decay are few, have long-range application prospect.Switzerland in 1991
Professor is with the nanoporous TiO of high-specific surface area
2Film is applied on the dye-sensitized solar cells, and photoelectric transformation efficiency arrives 7.1%.The laboratory photoelectric transformation efficiency of this dye-sensitized nano film solar battery is called by industry near business-like amorphous silicon solar cell
Battery becomes the important new direction that develops a kind of low price, efficient solar battery.1993,
Reported once more that Deng the people photoelectric transformation efficiency reaches 10% dye-sensitized solar cells, by 1997, its photoelectric transformation efficiency reached 10%～11%.The black dye of development in 1997 has widened 100nm than the absorption spectrum ranges of N3 dyestuff to infrared region.1998,
Adopt the alternative electrolytical all-solid-state dye-sensitized solar cell of liquid of SOLID ORGANIC hole mobile material to succeed in developing Deng the people, its monochromatic light conversion efficiency reaches 33%, thereby has caused global concern.This hull cell structure is: electro-conductive glass, the semiconductor working electrode of absorbing dye, electrolyte, accelerator material, electro-conductive glass.The utility model with dye-sensitized film solar cell and Lawn lamp in conjunction with together.
The utility model content
The purpose of this utility model is: at some problem that exists in the existing solar lawn lamp above-mentioned, provide a kind of cost cheaper, be subjected to sunshine illumination condition less-restrictive, the solar lawn lamp that duty is better and more attractive in appearance.
The utility model is taked following technical scheme: dye-sensitized film solar cell Lawn lamp, comprise the dye-sensitized film solar cell, dye-sensitized film solar cell, lampshade, lamp barrel section and Lawn lamp lamp stand constitute, dye-sensitized film solar cell and light sensitive diode place the lampshade top, are connected to battery, control circuit and light emitting diode in the lamp barrel section by lead; Light emitting diode (light emitting source) is placed in the lamp bucket; Battery and control circuit are close to the lampshade inwall, and make light can be not interrupted upwards not see through dye-sensitized solar cells and throw light on, be the battery Lawn lamp with respect to silicon, many light-emitting areas at top; The bottom of lamp bucket is provided with lamp stand, is used to be inserted in prop up Lawn lamp on the lawn.
The beneficial effects of the utility model are: owing to adopted the dye-sensitized film solar cell, this new type solar energy Lawn lamp has following advantage: cost is cheaper, and generating dutation prolongs, and light-emitting area increases, and can carry out more design for aesthetic.
Description of drawings
Fig. 1 is a dye-sensitized film solar cell Lawn lamp overall schematic
1 dye-sensitized film solar cell, 2 lampshades, 3 lamp barrel sections, 4 Lawn lamp lamp stands
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment: (1 in the accompanying drawing 1; Lampshade is seen (2) in the accompanying drawing 1; Dye-sensitized film solar cell and light sensitive diode are placed on the lampshade top, are connected to battery, control circuit and light emitting diode by lead; Light emitting diode is placed in the lamp bucket; Battery and control circuit are close to the lampshade inwall, and make light can be not interrupted upwards not see through dye-sensitized solar cells and throw light on, be the battery Lawn lamp with respect to silicon, many light-emitting areas at top; The lamp bucket is seen 3 in the accompanying drawing 1; An inserted link is used to be inserted in and props up Lawn lamp on the lawn, sees 4 in the accompanying drawing 1; Working electrode on the Lawn lamp lampshade is printed as the dye-sensitized film solar cell of pattern and literal, and is provided with light sensitive diode (keying of control lamp).
Make up the dye-sensitized film solar cell:, can realize the reduction of solar lawn lamp cost because dye-sensitized film solar cell itself just has low material cost and simple manufacture process;
This solar cell itself also has the characteristics of low light level response, still can generate electricity in no sunlight direct projection and general thick weather, simultaneously the Lawn lamp battery is charged;
By control dye-sensitized film working electrode semi-conducting material TiO
2With the nano particle size of ZnO, can make the dye-sensitized film solar cell state that is translucent, and still keep superperformance; Rational deployment battery and control circuit position are adjacent to the lampshade inwall, can realize the increase of solar lawn lamp overhead illumination face.
The dyestuff that the dye-sensitized film solar cell adopts can have multiple color to select, and is that the battery solid color has very big attractive in appearance going up to improve with respect to silicon;
Dye-sensitized film solar cell manufacturing process uses typography, makes the working electrode of this solar cell can be printed as various patterns, literal, can satisfy high-end enterprise and group user show luminous sign or literal on Lawn lamp requirement.
The solar cell part at Lawn lamp top can be bright, increased the solar lawn lamp illuminated area.Solar lawn lamp is realized the colorful demonstration at top simultaneously.The pattern and the literal of the preparation of dye-sensitized film solar cell working electrode typography, the application in solar lawn lamp.
