Description
- The present invention relates to a solar cell, particularly to a dye-sensitized solar cell with hybrid nanostructures.
- In DSSC (Dye-Sensitized Solar Cell), dye molecules are chemically absorbed by metal oxide semiconductor nanoparticles; then, the nanoparticles are spread on the cathode to function as a photosensitive layer; an electrolyte is interposed between the photosensitive layer and the anode to assist in electric conduction. DSSC has the following advantages:
- 1. The photosensitive particles have an effective light absorption area 100 times greater than the surface area of the electrode. Therefore, DSSC has very high light absorption efficiency, using a very small amount of material.
- 2. The photosensitive particles are fabricated via merely soaking the semiconductor particles in a dye solution and drying the particles with an inert gas. Therefore, DSSC has a simple and inexpensive fabrication process.
- 3. The dye of DSSC has a wide absorption spectrum in the range of visible light. Therefore, a single type of DSSC elements can harness a wide spectrum of solar light.
- 4. DSSC is semitransparent and suitable to be a construction material, especially a window material. For example, DSSC may be used as glass curtain walls of high-rise buildings to provide functions of sunlight sheltering, thermal insulation and power generation. Therefore, a building may have efficacies of power saving and power generation via using DSSC.
- Generally, a solar cell is expected to have low cost, low fabrication complexity, and high photovoltaic conversion efficiency. DSSC indeed has the characteristics of low cost and low fabrication complexity. However, the photovoltaic conversion efficiency thereof still needs improving. A R.O.C patent publication No. 201001724 disclosed a “Dye Sensitized Solar Cell Having a Double-Layer Nanotube Structure and Manufacture Method Thereof”. The nanotube structures can increase the electric conduction efficiency of DSSC. However, nanotubes have less area to absorb dye than nanoparticles. Thus is decreased the photovoltaic conversion efficiency of the prior-art DSSC.
- The primary objective of the present invention is to enhance the photovoltaic conversion efficiency of dye-sensitized solar cells.
- To achieve the abovementioned objective, the present invention provides a dye-sensitized solar cell with hybrid nanostructures, which comprises a negative-polarity conductive substrate, a positive-polarity conductive substrate, a metal oxide layer and an electrolyte. The metal oxide layer is arranged between the negative-polarity conductive substrate and the positive-polarity conductive substrate. The metal oxide layer has a plurality of nanoparticles and a plurality of nanotubes. The nanoparticles and nanotubes are arranged alternately. The metal oxide layer is adhered to the negative-polarity conductive substrate. The electrolyte is arranged between the negative-polarity conductive substrate and the positive-polarity conductive substrate to implement redox reactions of the metal oxide layer.
- The present invention also provides a method for fabricating a dye-sensitized solar cell with hybrid nanostructures, which comprises steps: fabricating nanotubes with an anodizing method; breaking off the nanotubes via a vibration method; mixing the nanotubes with nanoparticles to obtain a metal oxide mixture; and spreading the metal oxide mixture on a conductive substrate to obtain a working electrode of a dye-sensitized solar cell.
- The nanoparticles can effectively increase the contact area between the metal oxide mixture and dye and thus enhance the photovoltaic conversion efficiency of DSSC. The nanotubes can increase the carrier mobility to effectively transfer electric energy to the electrodes. The present invention combines the advantages of nanoparticles and nanotubes and offset the disadvantages thereof to obtain greater dye absorption area and higher carrier mobility and improve the photovoltaic conversion efficiency of a dye-sensitized solar cell.

- Refer to
FIG. 1 andFIG. 2 respectively diagrams schematically showing structures of a working electrode and a dye-sensitized solar cell according to one embodiment of the present invention. The present invention provides a dye-sensitized solar cell with hybrid nanostructures, which comprises a negative-polarityconductive substrate 10, a positive-polarityconductive substrate 20, ametal oxide layer 30 and anelectrolyte 40. Themetal oxide layer 30 is arranged between the negative-polarityconductive substrate 10 and the positive-polarityconductive substrate 20. Themetal oxide layer 30 has a plurality ofnanoparticles 32 and a plurality ofnanotubes 31. Thenanoparticles 32 andnanotubes 31 are arranged alternately. Themetal oxide layer 30 is adhered to the negative-polarityconductive substrate 10. Theelectrolyte 40 is arranged between the negative-polarityconductive substrate 10 and the positive-polarityconductive substrate 20 to implement redox reactions of themetal oxide layer 30. In the embodiment shown inFIG. 2 , themetal oxide layer 30 is arranged on one side of the negative-polarityconductive substrate 10; theelectrolyte 40 is arranged between themetal oxide layer 30 and the positive-polarityconductive substrate 20. Acatalytic layer 50 is arranged between theelectrolyte 40 and the positive-polarityconductive substrate 20. Thecatalytic layer 50 is made of platinum in this embodiment. The process of absorbing light and generating electricity is the basic principle of DSSC and will not repeat here. - The
nanotubes 31 are grown with an anodizing method. In this embodiment, themetal oxide layer 30 is made of titanium dioxide. Thenanotubes 31 are grown from titanium with an anodizing method. Then thenanotubes 31 are broken off with a vibration method and collected. Thenanotubes 31 andnanoparticles 32 are arranged alternately. The negative-polarityconductive substrate 10 and the positive-polarityconductive substrate 20 are made of ITO (Indium Tin Oxide). A dye sensitizer adheres to the surface of thenanoparticles 32 andnanotubes 31. - Refer to
FIG. 3 a diagram schematically showing the structure of a dye-sensitized solar cell according to another embodiment of the present invention. In this embodiment, theelectrolyte 40 is arranged on two sides of themetal oxide layer 30. Such a structure can also implement the redox reaction of DSSC. - The present invention also provides a method for fabricating a dye-sensitized solar cell with hybrid nanostructures, which comprises steps:
- S1: fabricating
nanotubes 31, wherein an anodizing method is used to grow a plurality ofnanotubes 31 from a metal substrate; in one embodiment, the metal substrate is made of titanium (Ti); - S2: fabricating a metal oxide mixture, wherein the
nanotubes 31 are broken off by vibration and then mixed withnanoparticles 32 to form a metal oxide mixture; - S3: fabricating an electrode, wherein the metal oxide mixture is spread on a conductive substrate to form a negative-
polarity conductive substrate 10 functioning as a working electrode; in one embodiment, the metal oxide mixture is spread on the conductive substrate with a spin-coating method. - The abovementioned steps can only fabricate the negative-
polarity conductive substrate 10. To complete a solar cell further needs the following steps: - S4: dye adhering, wherein the negative-
polarity conductive substrate 10 is soaked in a dye sensitizer to make dye adhere to the surface of thenanoparticles 32 andnanotubes 31; - S5: joining the negative-
polarity conductive substrate 10 with the positive-polarity conductive substrate 20 to complete a solar cell, wherein the positive-polarity conductive substrate 20 is adhered to one side of the negative-polarity conductive substrate 10 having the metal oxide mixture by anelectrolyte 40. - As the
nanoparticles 32 have larger contact area for adhering dye, they can effectively convert light energy into electric energy. However, there are only point contacts among particles. Therefore, thenanoparticles 32 have poor electric conductivity. Although thenanotubes 31 have smaller surface area, they can effectively conduct electricity to the conductive substrates via the tube structure thereof. The electricity generated by thenanoparticles 32 is transmitted to thenanotubes 31 via the contact points between thenanoparticles 32 and thenanotubes 31, and thenanotubes 31 collect and send out electricity. As dye also adheres to the surface of thenanotubes 31, thenanotubes 31 generate electricity too. - In summary, the
nanoparticles 32 increase the contact area between dye and the metal oxide mixture and thus enhance the photovoltaic conversion efficiency of the solar cell. Thenanotubes 31 increase carrier mobility and thus effectively transfer electricity to electrodes. The present invention integrates the advantages ofnanoparticles 32 andnanotubes 31 and offsets the disadvantages thereof to achieve large dye-adhering area and high carrier mobility so as to enhance the photovoltaic conversion efficiency of DSSC.
