- the present invention relates to a power supply device including a battery such as a solar cell (photoelectric conversion device) and a chemical battery.
- a battery such as a solar cell (photoelectric conversion device) and a chemical battery.
- Solar cells are a type of photoelectric conversion device that converts light energy into electric energy.
- the most widespread solar cells that use pn junctions of semiconductors or heterojunction of dissimilar materials absorb, for example, photons that have an energy larger than the band gap energy of the semiconductor among the photons incident on the pn junction. Then, electrons in the valence band are excited into the conduction band, and at the same time, holes are generated in the valence band.
- the electron-hole pairs generated in the semiconductor as described above are generated by the internal electric field formed at the pn junction, where electrons move toward the n-type semiconductor layer and holes move toward the p-type semiconductor layer. Electric power is generated.
- FIG. 9A is a schematic cross-sectional view of an example of a wet solar cell.
- the wet solar cell is mainly transparent substrate 1 1, such as glass, ITO (I nd i um T in Ox i de) transparent electrodes 1 2, such as, titanium oxide T i 0 2 semiconductor layer 1 4, such as the counter electrode 17, an electrolyte layer 16 held between the semiconductor layer 14 and the counter electrode 17, a substrate 19, and the like.

- the principle is as follows.
- the light absorbing substance 15 When the light absorbing substance 15 absorbs a photon incident on the semiconductor layer 14, the electrons in the light absorbing substance 15 are excited from the ground state to the excited state. Since an electrical connection is formed between the light absorbing substance 15 and the semiconductor layer 14 by a lipoxyl group or the like, electrons in the excited state move to the conduction band of the semiconductor layer 14 immediately, and It reaches the transparent electrode 12 via 14.
- cations generated by the light absorbing substance 15 losing electrons receive electrons from the anions of the electrolyte layer 16 and are electrically neutralized.
- the anion that has lost the electrons reaches the counter electrode 17 by diffusion and receives electrons from the counter electrode 17.
- the energy of a single photon is proportional to the frequency of the light and inversely proportional to the wavelength of the light. Since ordinary light such as sunlight contains light of various wavelengths, ordinary light is a group of photons having various energies.
- the energy difference between the electron in the ground state and the electron in the excited state that is, the energy required to excite the electron from the ground state to the excited state is also determined as a value unique to the substance ( Hereinafter, this energy is called "excitation energy Ex", and the wavelength of a photon with the same energy is written as ⁇ X.
- excitation energy Ex the energy difference between the valence band (ground state) and the conduction band (excitation state), that is, the bandgap energy is the excitation energy Ex.
- the energy difference between the ground state and the excited state of the light absorbing substance is the excitation energy EX.
- FIG. 8 is a graph schematically showing a conversion ratio of light energy to electric energy when light including light of all wavelengths near visible light uniformly enters a solar cell.
- FIG. 9B is a graph schematically showing a rate at which solar energy is converted into electric energy by the wet solar cell of FIG. 9A.
- Light falling from the sun to the Earth has the wavelength distribution shown in Figure 9B.

Compared to Fig. 9B, it can be seen that the tandem solar cell can use the long-wavelength component of sunlight that was discarded by the single-layer solar cell, and also increases the energy conversion efficiency of the short-wavelength component.

- a simple method is to use a series / parallel wiring pattern determined in advance as described above, fix it to this, and keep it unchanged.
- Another method is to make the battery matrix maintain the same output voltage even if the electromotive force of each layer changes due to changes in the wavelength distribution of the incident light or aging of the battery, etc. This is a method of changing the wiring pattern and changing the number of series connection stages.
