Problems solved by technology

[0011] This polarization phenomenon is unique to dye-sensitized solar cells using a liquid or solid electrolyte layer (the electrolyte layer includes organic solvents or ionic liquids containing redox nuclides, gels, etc.) Deterioration modes that cannot be imagined in some silicon-based solar cells (using monocrystalline silicon, amorphous silicon, etc.)

[0050] (4) Third embodiment (solar cell with degradation suppression function).

[0051] 1. Deterioration due to polarization

[0052] First, a description will be given of an example of deterioration of the power generation characteristics of the dye-sensitized solar cell due to the polarization phenomenon. For the three patterns of the external circuit connected to the dye-sensitized solar cell module (three states between the power collecting parts), the dye-sensitized solar cell module including eight dye-sensitized solar panels connected in series is compared with each other The time of the power generation characteristics changes.

[0053] Such as Figure 1A The first state shown in is a state in which a released state (open state) is provided at both ends of the power collecting part of the dye-sensitized solar cell module 101. In this case, the resistance value between the power collecting par...

Abstract

Disclosed is a controller for controlling short-circuit across positive and negative terminals of a dye sensitized solar cell for converting a light energy into an electrical energy. The controller includes: a voltage detecting section detecting a voltage developed across the positive and negative terminals of the cell; a current detecting section detecting a current caused to flow through the positive terminal of the cell; a judging section judging how a power generation state of the cell is, and whether or not a release state is provided across the positive and negative terminals of the cell in accordance with a value of the voltage detected by the voltage detecting section and a value of the current detected by the current detecting section; and a short-circuiting / releasing section short-circuiting or releasing across the positive and negative terminals of the cell in accordance with a result of the judgment made by the judging section.

Description

Technical field [0001] The present disclosure relates to a controller, a control method, and a solar cell. More specifically, the present disclosure relates to a controller and a control method that can suppress the deterioration of the power generation characteristics of a solar cell, and a solar cell. Background technique [0002] A solar cell, which is a photoelectric conversion element for converting sunlight into electric energy, uses sunlight as an energy source. Therefore, the impact of solar cells on the global environment is very small. Therefore, in recent years, it has been desired to further popularize solar cells. [0003] So far, crystalline silicon system solar cells using monocrystalline or polycrystalline silicon and amorphous silicon system solar cells have been mainly used as solar cells. [0004] On the other hand, in 1991 by Michael The dye-sensitized solar cell proposed by (Michael Glazer) et al. has attracted attention because of the high photoelectric conv...
