Perovskite solar cell, and energy interconversion power generation method using chemical reaction by mixture of power generating material and good conductor in dye-sensitized solar cell

Abstract

To solve the problem that conventional power sources that generate electricity using the photoelectric effect, such as solar cells, cannot generate electricity at night when the light energy (light intensity) required for electricity generation is not available, because they use a light source of an external device.SOLUTION: A mixture of a metal such as titanium dioxide and a material with a perovskite structure such as gray titanite, or a dye molecule, which has the material characteristic of interconversion between electric energy and light energy, and a highly conductive metal or a carbon-based good conductor is processed and mixed in powdery form or solution form. The mixture is enclosed in a power generator and is temporarily energized from an external power source or is irradiated from an external light source. The mixture is then subjected to the interconversion of the electrical energy and the light energy within a device. The problem is solved by a power generation method that uses the chemical reaction of this "mixture of power generation materials and good conductors used in perovskite solar cells or dye-sensitized solar cells".SELECTED DRAWING: None

[0003] Dye-sensitized solar cell technology Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional photovoltaic power generation devices such as solar cells generate electricity by using the light energy of a light source outside the device, so there was a problem that they could not generate electricity when the light energy (amount of light) required for power generation was not available, such as at night or during rainy weather. [Means for solving the problem]

[0005] To address this issue, "a mixture of metals such as titanium oxide and substances with a perovskite structure such as perovskite, or dye molecules," which have the material property of being able to convert between electrical energy and light energy, and "highly conductive metals such as copper and aluminum" or "good carbon-based conductors such as carbon allotropes" are processed into powder or solution form and mixed together in appropriate amounts and ratios to ensure that the constituent substances are evenly distributed. This mixture is sealed in a power generation device, and electrical energy is temporarily supplied from an external power source (energized) or light energy is temporarily supplied from an external light source (irradiated). The mixture then enters a state in which light is emitted and electricity is generated simultaneously within the device (a state in which mutual conversion between electrical energy and light energy is taking place). The problem will be solved by using a method of generating electricity that utilizes the chemical reaction (energy interconversion action) of this "mixture of power-generating materials and good conductors of perovskite solar cells and dye-sensitized solar cells."
