Description

A kind of inverted structure organic/polymer solar battery
Technical field
The present invention relates to photoconductive organic semiconductor devices field, particularly a kind of inverted structure organic/polymer solar battery.
Background technology
Along with the continuous progress of human society, improving constantly of living standard, to the rapid growth of energy demand, global energy crisis is increasingly serious.Simultaneously for the needs such as environment of preserving our planet, people have invested the regenerative resource such as solar energy, Hydrogen Energy increasing sight.The solar cell converted solar energy into electrical energy based on photovoltaic effect is the focus studied both at home and abroad always, will become the important component part of renewable new forms of energy from now on.
At present, solar cell ripe on market is mainly the inorganic solar cell such as based single crystal silicon, polysilicon, amorphous silicon, GaAs, indium phosphide and polycrystalline film compound semiconductor, but because inorganic semiconductor solar cell is very high to the requirement of material purity, and expensive, therefore its application is very limited.
Organic photovoltaic phenomenon was just found as far back as 1958, utilized organic semiconductor to prepare photovoltaic device and first made a breakthrough in 1986, make people tentatively see the application prospect of organic photovoltaic cell.But the highest energy conversion efficiency of current organic photovoltaic cell is about 9%, distance commercialization also has one section of larger distance.Therefore, the research of organic photovoltaic cell also faces very large challenge, and only have acquisition high efficiency higher, the device of stable performance, its business-like production of ability, is applied to all spectra that current inorganic solar cell is applied.
In order to improve its energy conversion efficiency, numerous chemists, physicist and material scholar angularly start with from materials synthesis, device architecture, device preparation, conduct in-depth research polymer solar cells.At present, also there are some problems in polymer body heterojunction solar cell, its performance is restricted, these challenges mainly comprise: the polymeric material 1) as p-type semiconductor and photoactive layer mostly is impalpable structure, degree of crystallinity is lower, and intermolecular force is more weak, and photo-generated carrier mainly moves in intramolecular conjugated bonds, then more difficult in intermolecular migration, thus cause the carrier mobility of material lower by (10 -4cm 2v -1s -1), before being collected to form extrinsic current, easily there is compound and loss in photo-generated carrier.Therefore, cause the short circuit current of device and fill factor, curve factor on the low side; 2) absorption bands of most of conjugated polymer all concentrates on visible-range, and the spectral response range of active layer is narrow, lower to the solar radiation utilance of region of ultra-red, causes the response spectrum of battery not mate with solar earth radiation.Therefore, lower to the utilance of sunlight, affect energy conversion efficiency; 3) also there is a technical bottleneck in polymer body heterojunction solar cell, and high open circuit voltage and the absorption to sunlight wide region are difficult to get both simultaneously.This is because, the open circuit voltage V of device oc, Built-in potential V bidetermined by the difference of highest occupied molecular orbital (HOMO) energy level of donor material and minimum non-occupied orbital (LUMO) energy level of acceptor material.Improve the open circuit voltage of device, often to reduce highest occupied molecular orbital (HOMO) energy level (because the space that relatively can change of the lumo energy of acceptor material is little) of donor material, this just means that the band gap of donor material broadens, and declines with the matching degree of solar spectrum.4) at device stability and in the life-span, compared with practical requirement, very large gap is also had.
In general, the structure of conventional polymer body heterojunction solar cell is stacked gradually by substrate, anode and resilient coating thereof, photoactive layer and negative electrode and forms.Briefly, be exactly anode on a glass substrate, negative electrode on the outer surface, is prepared by last plated film preparation section.Recently, a kind of polymer body heterojunction solar cell device architecture of inverted structure is also developed, namely device is successively by glass substrate, negative electrode, cathode interface layer, photoactive layer, formation is stacked gradually with anode, cathode interface layer adopts the conjugated polymer of the polarity unit containing polar group or ionic group, or the poly-dielectric of its correspondence is formed, photoelectric conversion efficiency and stability (the Chinese invention patent application book of 2011 such as REFERENCE TO RELATED people of device can be significantly improved, application number: 201110309043.4, patent name: polymer body heterojunction solar cell of a kind of inverted structure and preparation method thereof).But the conjugated polymer of the polarity unit containing polar group or ionic group is difficult to the uniform solution of preparation in water or alcohol, need to use appropriate organic acid to promote structure adaptability; And the introducing of acidic materials, there is certain corrosiveness to electrode, have certain influence to device long-time stability.In addition, polymer property is by the obvious effect of synthesis condition, and the polymer property that different reaction batches obtains has certain difference.
