At present, some kind of “magic” coating can be used to replace “silicon” in solar power generation.If it hits the market, it could significantly reduce the cost of solar power and bring the technology into everyday use.
Using solar panels to absorb the sun’s rays, and then through the photovolt effect, the radiation of the sun’s rays can be converted into electrical energy – this is commonly known as solar power generation, which refers to the solar panels of the main material is “silicon”.It is only because of the high cost of using silicon that solar power has not become a widely used form of electricity generation.
But now some kind of “magic” coating has been developed abroad can be used to replace “silicon” for solar power generation.If it hits the market, it could significantly reduce the cost of solar power and bring the technology into everyday use.
Fruit juice is used as pigment material
One of the leading research institutions in the field of Solar power is the MIB-Solar Institute at the University of Milan Bicocca, Italy, which is currently experimenting with a coating for Solar power called DSC Technology.DSC stands for dye-sensitised Solar Cell.
DSC Technology The basic principle of this solar power coating is to use chlorophyll photosynthesis.Researchers say the pigment that makes up the paint absorbs sunlight and activates electrical circuits that connect the photoelectric system to generate electricity.The pigment raw material that coating uses, also can use the juice of all sorts of fruit to process, wait like juice of blueberry juice, raspberry, red grape.The colors suitable for the paint are red and purple.
The solar cell that goes with the coating is also special. It uses a special printing machine to print nanoscale titanium oxide onto a template, which is then immersed in organic paint for 24 hours. When the coating is fixed on the titanium oxide, the solar cell is made.
Economical, convenient, but inefficient
It’s easy to install.Normally we see solar panels installed on eaves, roofs, just a part of the surface of a building, but the new paint can be applied to any part of the surface of a building, including glass, so it is more suitable for office buildings.In recent years, the exterior style of all kinds of new tall buildings all over the world is suitable for this kind of solar power coating.Take the UniCredit building in Milan as an example. Its exterior wall occupies the vast majority of the building area. If it is coated with solar power generation paint, it is very cost-effective from the point of view of energy saving.
In terms of cost, paint for power generation is also more “economical” than panels.The solar-power coating costs one-fifth as much as silicon, the main material for solar panels.It’s basically made up of organic paint and titanium oxide, both of which are cheap and mass-produced.
The advantage of the coating is not only that it is low cost, but also that it is far more environmentally adaptable than “silicon” panels.It works in bad weather or dark conditions, such as overcast or at dawn or dusk.
Of course, this kind of solar power coating also has the weakness, that is not as durable as “silicon” board, and the absorption efficiency is lower.Solar panels typically have a shelf life of 25 years, researchers said.In fact, many of the solar energy inventions installed 30-40 years ago are still in effect today, while the design life of solar power paint is only 10-15 years;Solar panels are 15 percent efficient, and electricity-generating coatings are about half as efficient, at about 7 percent.
