The organic film double-function device with photoelectric conversion and electrooptic conversion includes metal cathode, organic compound film layer and transparent anode. When it is used as electro-optical conversion device, sun light is utilized and absobed and converted into solar energy to provide working power supply for itself and can send bright light, and when it is used as photoelectric conversion device, solar energy can be converted into electric energy, and can be used in light detector, photoelement and UV irradiation monitoring instrument for monitoring environment.
Description
Technical field: the invention belongs to field of optoelectronic devices, relate to a kind of improvement to photovoltaic device.Light → electricity conversion can take place in photovoltaic device under sunlight or UV-irradiation, can launch light when applying direct voltage.
Background technology: photovoltaic device in the past is divided into inorganic semiconductor and organic two classes:
To inorganic semiconductor, in the time of near extraneous photoirradiation semiconductor p-n junction district, as long as the energy of incident light is greater than its band gap width, just might produce intrinsic excitation and produce electron-hole pair, this photohole and light induced electron be electronics trend n district, trend p district, hole under interior field action, p district and n district will accumulate excessive hole and excess electrons respectively like this, thereby form an electric field, just have photogenerated current and pass through when external connecting circuit.This photovoltaic device is applied to solar cell and photodiode widely.But this device does not have lighting function when leading to direct current.
Recently the organic photovoltaic devices of carrying out has individual layer and multilayer device, and is very big to single layer device photovoltaic property and the electrical relation of electrode, and duty ratio is also bad.Tang invents a kind of double-deck organic film photovoltaic device, and its characteristic depends primarily on the interface [C.W.Tang, Appl phys Lett, 48 (2) 1986 183-185] of two organic layers, but does not report relevant electroluminescent properties.
Summary of the invention: the object of the invention is to solve only has a kind of photoelectric converting function in the background technology, it can only be used for opto-electronic conversion and not have the function problem of electric light conversion, when needing external power supply as electro-optical conversioning device, make the device cost height, power source life is short, problems such as poor stability, to propose difunctional be the conversion of light → electricity and electricity → light translation function device in the present invention for achieving the above object, a kind of n district and electron acceptor of making the photoelectric converting function device with rare earth compounding will be provided, TPD or NPB do p district and electron donor, when ultraviolet light or solar light irradiation, realize opto-electronic conversion.
The present invention includes metallic cathode 1, organic compound thin film layer 2, organic compound thin film layer 3, transparent anode 4, one side is a metallic cathode 1, opposite side is a transparent anode 4, is gripped with organic compounds thin layer 2 and organic compound thin film layer 3 between metallic cathode 1 and transparent anode 4.It is RE (A) that organic compound thin film layer 2 adopts rare earth compounding
3B; Organic compound thin film layer 3 adopts TPD and/or NPB and and/or diamine derivative.
When the present invention works as shown in Figure 1: its two functions all mainly occur in the near interface of two organic thin film layers.The organic layer that has two kinds of difference in functionalitys in this device.When utilizing the electric driving device of device self, this device then has photoelectric converting function.Promptly when utilizing the solar light irradiation transparent anode, can record short circuit current and open circuit voltage between transparent anode and the metallic cathode with DC ammeter.Organic compound thin film layer near metal electrode is an electron acceptor, and the organic compound thin film layer of close transparent anode is an electron donor.Metallic cathode and transparent anode are respectively electron collection layer and collecting layer, hole.
When utilizing electric driving device, this device then has the electric light translation function.When metallic cathode and transparent anode apply negative voltage and positive voltage respectively, can launch bright light from the transparent anode side, this moment, the organic compound thin film layer then became electron transfer layer and hole transport-emission layer respectively.Transparent anode is the hole injection layer light output layer of holding concurrently, and metallic cathode is an electron injecting layer.
The difunctional organic optoelectronic device that the present invention proposes is that organic interface layer effect device is during as photovoltaic device, TPD or NPB layer are as electron donor, the rare earth compounding layer is made electron acceptor, being actually under rayed that exciton takes place to decompose at two organic interface places is electric charge carrier generation ionization, electronics moves to the electron acceptor direction, move to the electron donor direction in the hole, so at the excessive electronics of electron acceptor district accumulation, form additional electric field in the excessive hole of accumulation, electron donor district, this additional electric field externally will produce photogenerated current by circuit.Device is under direct voltage drive, from transparent anode to TPD or NPB injected hole, inject electronics from metallic cathode to rare earth compounding, by partially TPD or NPB one side are luminous compound and by the exciton deexcitation and luminous at the interface, some variations take place with driving voltage in this luminous zone, mainly be to become with voltage because of emission spectrum, under low voltage drive, except TPD or NPB emission, also present superposition emission band by long wave, it is not from rare earth compounding and TPD or NPB, but from the interface of two organic layers.We think that it is the interface emission that is called exciplex.When selecting RE=Y, during light emitting ionic, exciplex emission relative intensity is not higher for La, Gd etc.We find enjoyably that also the exciplex emission is strong more, and its light-electric conversion effect is also just good more.
Good effect of the present invention: opto-electronic conversion and electro-optical conversioning device that the present invention adopts the organic compound thin film layer to make are a kind of lighting source and dull and stereotyped active displays that does not need additional power source.When above-mentioned device during as electro-optical conversioning device, promptly utilize device to absorb to come from the light of the sun and convert thereof into solar energy and provide working power for self, device cost is reduced greatly, because the sun constantly replenishes self power supply its stability and life-span are improved, having solved the background technology electro-optical conversioning device needs that external power supply, cost height, power source life are short, the problem of poor stability.It is again a kind of organic electroluminescence device, gives off bright light under five volts～20 volts driven, and emission spectrum changes with driving voltage, then can be used for lighting source and dull and stereotyped active display; When above-mentioned device during as electrooptical device, can become electric energy to solar energy converting when promptly utilizing this device of the rayed that comes from the sun, then it can be used for the UV-irradiation monitor of photo-detector, photovoltaic cell and environmental monitoring.
