As shown in the review article, many have been made, but the one that is in practical use is a system that fully charges the secondary battery using solar cells. In addition to the two-stage type that stores electricity generated by solar cells in a secondary battery, there is also an n-type Ti○
An electrode made of a semiconductor such as 2, a metal such as platinum,
Alternatively, the semiconductor electrode is immersed in an electrolytic solution together with an electrode made of a semiconductor such as p-type GaP, and the semiconductor electrode is irradiated with light to cause charge separation (holes in the conductive band, electrons are generated in the conductive band), photo-induced Attempts have been made to oxidize and reduce substances in the electrolyte with the generated charge and store them as active materials, and use this during discharge, but this has not yet reached the level of practical use.

の材料に限られるのが現状である。In order to cause the subsequent oxidation and redundancy to occur with photo-excited charges, the oxidation and reduction portions of the substances in the electrolyte are separated from the upper end of the conductive band of the semiconductor electrode by two-part, reduced-form fI. '1 is'
Below the lower end of the Ffi 7C band, the filter that causes as much charge separation as possible from the
, it is necessary that the bandgap of the semiconductor * pole be small, but if the bandgap is too small, the condition (2) cannot be satisfied and the subsequent electrochemical reaction will not proceed. therefore,
The bandgap of a semiconductor that satisfies the conditions ① and ②, absorbs sunlight or fluorescent lamp light, and promotes reactions efficiently is approximately 1 to 2.5 eV. A semiconductor with (n-type S i ~
1.1 eV, n-type Ga As ~ 1.35 e

is stored in the positive electrode material, and this flow of electrons is the function of the battery, but the energy consumed when transferring electrons between Cu+ and the positive electrode material is small t 1
is called the activation energy of cargo movement. Of course, the lower the activation energy, the more quickly the electron transfer will take place, and the smaller the battery's charge (event) will be.Z r
When S 2 was doped with Nb, the above-mentioned activation energy was lowered, resulting in smaller polarization.
