Definitions
- the present invention relates to a photoactive nanocomposite that can be used in a solar cell implementing the photovoltaic effect, in a light emitter or in a photodetector.
- This type of photoactive component traditionally comprises a pair of donor-acceptor semiconductor elements. It is known that to observe a transfer of charges between donor and acceptor, it is necessary that the respective energy levels of one and the other are compatible.
- Photovoltaic devices based on amorphous or microcrystalline silicon in a thin layer are known. These devices have interesting yields of 6 to 10%. However, they are unstable (aging). Materials of the interpenetrating network-conjugated polymer and fullerene type or its derivatives are also known. The efficiency of these systems is notably limited by the transport of charges in organic materials. Indeed, in most organic conductors, the mobility of the charges is low (less than 10 "4 Cm 2 Vs " 1 ), because of the presence of charge traps such as oxygen. In addition, they are not very stable in the air.
- One way to overcome this limitation of charge transport is to combine, for example, an electron-donor conjugated polymer with an inorganic semiconductor, as an electron acceptor.
- the present invention relates to a new type of interpenetrating network including an organic compound and silicon nanowires.
- the organic compound may be an electron donor or acceptor and acceptor or electron donor silicon nanowires.
- a photoactive nanocomposite comprising at least one pair of donor-acceptor semiconductor elements.
- One of the elements is formed of doped nanowires of structure sp3.
- the other of the elements is an organic compound.
- said nanowires have the following characteristics:
- the element with structure sp3 is doped n
- the element with structure sp3 is doped p
- the organic compound is a conjugated polymer
- the organic compound is a small molecule
- the sp3 structure element is silicon
- the element with sp3 structure is germanium
- the nanowires have a diameter of less than 100 nm, preferably less than 10 nm,
- the nanowires have been functionalized by a surface treatment
- the organic compound element is a conjugated polymer forming part of the assembly formed by: polyaniline, polypyrrole, polyacetylene, polyparaphenylene, polyparaphenylenevinylene and its derivatives, poly-para-phenylene sulfide, polyisothionaphthene, polyheptadyne poly (3,4-ethylenedioxythiophene) (PEDOT) and its family, polysquaraines, polyfluorene, polythiophene and its derivatives, polyfluorenone and its derivatives, polythienylenevinylene and its derivatives, the organic compound element is a small molecule forming part of the group formed by phthalocyanine and its derivatives, porphyrin and its derivatives, chlorophyll and its derivatives, perylene and its derivatives, pentacene, tetracene and all polyene derivatives substituted or not, merocyanine and its derivatives, naphthalocyanine and its derivatives
- the invention also relates to the method of manufacturing this photoactive nanocomposite component. Generally,
- nanowires are formed on a growth substrate
- the organic element is associated with the nanowires so as to form an active layer
- this active layer is placed between two electrodes.
- Different implementations of this process, each having specific advantages are proposed:
- the growth of the nanowires is obtained in two different ways:
- a gold layer with a thickness of the order of 1 nm is deposited on a growth substrate covered with a transparent conductive oxide layer or on an oxide layer; the substrate covered with this layer is annealed to form the gold layer, the nanowires are deposited and the gold is dissolved chemically. Either the nanowires are taken or the nanowires are left in place on the transparent substrate covered with ITO.
- the nanowires are functionalized.
- the formation of the nanowires is obtained by chemical vapor deposition (CVD) of nanowires of element with structure sp3. - This chemical vapor deposition process can be assisted by low frequency plasma, radio frequency or microwave (PECVD: Plasma Enhanced Chemical Vapor Deposition).
- the conductive device substrate is either a silicon substrate or a glass substrate on which a conductive transparent oxide layer has been deposited.
- the nanowires are taken,.
- the sampled nanowires are functionalized and are solubilized in the organic element which is a conjugated polymer,
- the active layer obtained is deposited on a device substrate covered with a transparent layer forming a first electrode
- said mixture is deposited by coating (centrifugal or laminar).
- the nanowires forming a mat on the ITO layer which constitutes a first electrode are impregnated with polymer after functionalization to form the active layer, or the nanowires formed on the ITO layer forming a first electrode are covered with a layer of small molecules obtained by evaporation under vacuum.
- the growth substrate becomes the device substrate.
- Figure 1 schematically shows a photovoltaic cell.
- Figure 2 shows the band diagram of each of the elements implemented in a photovoltaic device with an ITO electrode.
- Figure 3 shows a band diagram of each element implemented in a photovoltaic device with a gold electrode.
- Figure 4 is a schematic representation of the realization of nanowires according to the invention.
- Figure 5 is a schematic representation of a first embodiment of the method of the invention.
- FIG 6 is a schematic representation of a second embodiment of the method of the invention.
- the photoactive nanocomposite 3 of the invention comprises a pair of donor-acceptor semiconductor elements. One of these elements is formed of nanowires 7 with sp3 structure, the other of these elements being a conjugated polymer 8.
- FIG. 1 shows a cell comprising a glass substrate 1, a tin-doped indium oxide (ITO) electrode 2, a photoactive nanocomposite 3 and a second electrode 4.
- the nanowire nanowires 3 of the nanocomposite 3 are electron acceptors (n Si) and the polymer element 8 is an electron donor (polyhexylthiophene (P3HT) regio-regulator).
- the data shown in FIG. 2 is implemented, the active layer 3 is placed between an indium oxide indium oxide 2 doped with tin (ITO) and an aluminum electrode 9 .
- ITO indium oxide indium oxide 2 doped with tin
- the active layer 3 is placed between a tin-doped indium oxide (ITO) electrode 2 and a gold electrode 10, FIG. 3 represents the band diagram of these materials. .
- ITO indium oxide
- Figures 2 and 3 respectively represent in each of these cases, the Fermi levels of the materials forming the nanowires 7, the organic compound 8 and the materials constituting the electrodes 9 and 10.
- the materials used must be optimized. We can act on the following parameters:
- the Fermi level of nanowires 7 is adapted by determining the dopant concentration of silicon. It is necessary that the silicon nanowires 7 are p-doped electron acceptors (since the P3HT is an electron donor, type n).
- the diameter of the nanowire it is known that the energy of the forbidden band varies according to the diameter of the nanowires 7. For diameters greater than about 3 nanometers, the properties of the nanowires 7 are those of the bulk material. As the diameter decreases, the gap energy increases. It is greater than 3 electron volts / eV for a diameter less than 1 nm.
- the nanowires 7 are produced.
- a very thin gold layer 6, of the order of one is deposited first. 1 nm thick either on a tin-doped indium oxide (ITO) coated glass growth substrate, or on a silicon growth substrate.
- the substrate 5 coated with gold is then annealed at a temperature of the order of 400 to 600 ° C., which makes it possible to obtain a layer 6, an aggregator of gold.
- Nucleation and growth of the silicon nanowires 7 are then produced by a chemical vapor deposition process. This mechanism takes place at temperatures above the gold-silicon eutectic (375 ° C.). Indeed, under these conditions, during the deposition, the silicon atoms that reach the surface of the Growth substrate diffuses through the gold and precipitates at the gold / substrate interface.
- the diameter of the nanowires 7 is determined by the size of the gold aggregates. It is thus possible to grow the nanowires 7 perpendicular to the surface of the growth substrate 5 and preferably following the same crystalline orientation when the substrate itself is composed of crystalline silicon. It is also possible to obtain nanowires 7 by filling a previously gilded nanoporous alumina membrane; the membrane is then chemically dissolved.
- nanowires 7 After the formation of nanowires 7 the gold is dissolved.
- the silicon nanowires 7 are taken out and then dissolved in the polymer 8. The solubilization is improved by counting the two elements of the mixture by functionalization of the surface of the nanowires 7. what is stated above.
- the mass proportion of the nanowires 7 in the polymer 8 is optimized.
- the photo-induced absorption and luminescence quenching of interpenetrating network mixtures at different rates make it possible to characterize the charge transfers produced in the material.
- the polymer 8 is advantageously regioregular P3HT.
- the nanowires 7 are held in place on the growth substrate 5 which becomes the device substrate and after dissolution of the gold and functionalization, these nanowires 7 are impregnated with polymers 8.
- the ITO layer or the silicon device substrate constitutes an electrode 2, the second electrode 9, 10 is then deposited on the upper face of the component.
