Dye-sensitized solar cell: the hope of future green energy Dye-sensitized solar cell (DSSCs for short) is a new type of solar cell technology, which has the characteristics of efficiently converting solar energy into electricity, and is widely regarded as the hope of future green energy.

Working principle: the miracle of photoelectric conversion The working principle of Dye-sensitized solar cell can be divided into three main processes: light absorption, electron transmission and charge separation.

Firstly, sunlight shines on the conductive glass on the surface of the battery, which then enters the photosensitive dye layer. Photosensitive dyes absorb photons and excite them to high-energy states, producing electron hole pairs.

Next, the excited electrons will flow along the conductive glass through the electrolyte or conductive material in the dye layer. At the same time, the holes will also return to the infrared matrix through the conductive material inside the dye adsorption layer.

Finally, electrons and holes separate at the interface between the conductive material and the infrared matrix, and electrons enter the conductive glass to form a current, while holes return to the electrolyte to maintain charge balance. This achieves the conversion of light energy to electrical energy.

Manufacturing method: The simple and flexible manufacturing method of Dye-sensitized solar cell is simpler and more flexible than the traditional silicon based solar cells.

Firstly, prepare a conductive glass substrate. Common conductive glasses include tin fluoride conductive glass and zinc oxide conductive glass.

Next, apply a dye adsorption layer. The dye adsorption layer is composed of photosensitive dyes and nanocrystalline particles, which are used to enhance the light absorption capacity of the battery.

Then, an electrolyte liquid is added above the dye adsorption layer. Electrolyte organic liquids are the medium for electron transport in batteries.

Finally, appropriate barrier materials are added to prevent electrolyte liquid leakage, and the anode and cathode are connected to form a complete Dye-sensitized solar cell.

Conclusion: Dye-sensitized solar cell is a new type of solar cell technology that can efficiently convert solar energy into electricity. Through processes such as light absorption, electron transfer, and charge separation, it can convert solar photons into electrons, achieving the miracle of photoelectric conversion.

Compared with traditional silicon based solar cells, the production of Dye-sensitized solar cell is simpler and more flexible, mainly including the steps of preparing conductive glass substrate, coating dye adsorption layer, adding electrolyte liquid and barrier materials, and finally connecting anode and cathode.

The research, development and application of Dye-sensitized solar cell will make an important contribution to the development of sustainable energy in the future.
