Solar panels are used to absorb sunlight, and then through the photovoltaic effect, the radiant energy of sunlight can be converted into electrical energy. This is what we commonly know as solar power generation. The main material of solar panels mentioned is "silicon". . Just because of the high cost of using silicon, solar energy has not been a widely used power generation method.
However, at present, foreign countries have developed a kind of "magic" paint that can be used instead of "silicon" for solar power generation. If it can be successfully put into the market, it can greatly reduce the cost of solar power generation, so that solar power technology is widely used in everyday applications.
Fruit juice as pigment material
The Mib-Solar Institute at the University of Milan, Bicocca is one of the most advanced research institutes in the field of solar power generation. It is currently experimenting with a solar power coating called DSC technology. DSC stands for Dye-sensitised Solar Cell - meaning "pigment-sensitized solar cell."
The basic principle of DSC technology solar-powered coatings is the use of photosynthesis of chlorophyll. The researchers said that the pigments that make up the paint, after absorbing sunlight, can activate the photovoltaic system and connect the circuits to generate electricity. Pigments used in paints can also be processed with fruit juices of various types, such as blueberry juice, raspberry juice, and red grape juice. The colors that are most suitable for the paint are the red and purple colors.
The solar cells associated with the paint are also very special. They use a special type of printing machine to print nano-sized titanium oxide on the template, and then soak the template in the organic coating for 24 hours. After the coating is fixed on the titanium oxide, Solar cells are made.
Economical, convenient, but inefficient
It is easy to install. The solar panels we usually see are installed on the roof or on the roof, but only use a part of the surface of the building. However, this new coating can be applied to any part of the building surface, including glass, so it is more suitable. For office buildings. In recent years, the appearance style of various high-rise buildings newly built in the world is suitable for this type of solar power generation paint. Taking Milan's Unicredit Bank Building as an example, its exterior wall accounts for the vast majority of the entire building area. If solar power paint is applied, it is very cost-effective from the perspective of energy conservation.
From a cost perspective, power generation coatings are also "economical" than panels. The cost of this solar power coating is only 1/5 of that of the main solar panel material. It consists essentially of organic coatings and titanium oxide, and the raw materials are inexpensive and can be produced in large quantities.
The advantages of this coating are not only low cost, but also adapt to the environment more than "silicon" panels. It can be effective under conditions of bad weather or dark lighting conditions, such as cloudy days or dawn and dusk.
Of course, this solar power coating also has weaknesses, that is not as good as the "silicon" board durability, and the absorption efficiency is low. According to researchers, the shelf life of solar panels is generally 25 years. In fact, many solar energy installations installed 30-40 years ago are still in effect. However, the design life of solar power generation coatings is only 10-15 years; the absorption efficiency of solar panels is 15%, and the efficiency of power generation coatings is only the former. About half, only about 7%.
Of course, the weakness of solar paint absorption efficiency can be offset by the advantages of large area smearing. Therefore, it still offers the possibility of solar power.
