Embodiment
Below, with reference to accompanying drawing, the inventive embodiment involved by the application is described.
Shown in Fig. 1 as the embodiment of the present invention, the basic comprising with the capacitor of photovoltaic performance that titanium dioxide generating body and silicon dioxide generating body are combined and form.
In this embodiment, 1 and 3 is the glass substrates respectively with FTO (tin oxide of doped with fluorine) layer 2 and FTO layer 4, and FTO layer 2 and 4 plays function as electrode for capacitors.In addition, substrate 1 and 2 also can use PET resin or PEN resin.
5 is titanium dioxide generating body, and 6 is silicon dioxide generating body, and 7 is platinum film.
8 is electrolyte, can utilize colourless electrolyte, that is, by 1-ethyl-3-methylpyridinium iodide imidazoles
0.4mol, tetrabutylammonium iodide 0.4mol, 4-tert .-butylpyridine 0.2mol, guanidinium isothiocyanate 0.1mol are that the electrolyte etc. obtained prepared by solvent with carbonic allyl ester solution.
Titanium dioxide generating body 5 electrifies when illuminated ultraviolet light, and silicon dioxide generating body 6 is by electrifying from ultraviolet light to the irradiation of visible ray and even infrared light.
FTO film 2 and 4 plays function as the opposite electrode of capacitor.
Titanium dioxide generating body 5 and silicon dioxide generating body 6 electrify when illuminated infrared light ~ ultraviolet light, put aside and charge between the produced electric charge that do not have to electrify during connected load plays function FTO film 2 and 4 at the opposite electrode as capacitor.In such a state during connected load, the electric charge put aside is discharged by load.
Below, be described by the situation of figure to discharge and recharge of experimental result.
The area of the capacitor used in experiment is 2cm × 3cm, and use fluorescent lamp as radiation source, illumination is now 600lux.
Shown in Fig. 2 is after long-time connected load, within every 10 seconds, repeatedly carries out the change of the disconnection of load and output current when being connected, and shown in Fig. 3 is the change of output voltage now.
In Fig. 2, steady-state current value during connected load is 28.6 μ A.
When disconnecting load afterwards at 10 seconds, output current becomes 0.
Be that the such discharging current of about 4 times of 115.3 μ A flows through with maximum instantaneous value during connected load after they 10 seconds, its after-current is decayed to steady-state current value 28.6 μ A.
When again disconnecting load after 10 seconds, output current becomes 0, and discharging current large during connected load after they 10 seconds flows through, and its after-current is decayed to steady-state current value.
After, electric current repeats this change.
The details of discharge and recharge output current wave is shown in Fig. 3.From this waveform observation, the capacitor of presumption embodiment is integrating circuit.
Output voltage is 0.2508V when disconnecting load as shown in Figure 4, is 0.29492V, is about 10 times during connected load, in connected load and in disconnection load, do not have change in voltage.
As can be seen from Figure 3 large during connected load output current flows through.
By detecting this output current, can the connection of reliably detection load.
In addition, electric charge is in this case the light of ubiquitous infrared light under comprising usual environment by irradiation and obtains, and does not therefore need to prepare battery etc. in addition in order to the connection of detection load.
Output current change when being 20 seconds with the opening time of load is shown in Fig. 5.
In Fig. 5, steady-state current value during connected load is 28.6 μ A.
When disconnecting load afterwards at 10 seconds, output current becomes 0.
Be that the such discharging current of about 3 times of 86.7 μ A flows through with maximum instantaneous value during connected load after they 10 seconds, its after-current is decayed to steady-state current value 28.6 μ A.
When again disconnecting load after 10 seconds, output current becomes 0, and discharging current large during connected load after they 10 seconds flows through, and its after-current is decayed to steady-state current value.
After, electric current repeats this change.
Output current change when being respectively 1 second with the disconnection of load and connect hours is shown in Fig. 6.
Now maximum output current is 415.5 μ A, reaches 14.5 times of steady-state current value.
Finally, exemplified as the invention solar cell applicatory of the application.
Shown in Fig. 7 (a) is the capacitor only with titanium dioxide generating body 5.
Shown in Fig. 7 (b) is the capacitor using dye-sensitized titania to replace titanium dioxide generating body 5.
Shown in Fig. 7 (c) is the capacitor only with titanium dioxide silicon generating body 6.
In addition, though do not illustrate with embodiment, the capacitor using dye-sensitized titania to replace the titanium dioxide generating body 5 of Fig. 1 can be also set to.
