Solar cells have many advantages so why is not yet widely used?

No loss of operation, no noise, no harmful emissions, no maintenance costs due to high durability, but why aren't there many applications for solar cells?

Born in 1946, solar cells have become one of the greatest inventions in the energy industry, with the potential to completely replace traditional fossil fuels.

No loss of operation, no noise, no harmful emissions, no maintenance fees due to high durability . just enough that solar cells get a lot of positive reviews.

Solar cells have many advantages. But why superiority is so that not many places apply it?

Simply because solar cells still have some limitations. So what is it, let's find out!

1. High price

The cost of installing a solar cell system is about 15,000 - 40,000 USD (300 million - 1 billion VND).

If you only want to reduce your monthly electricity bill, you can install several batteries according to your needs, with the price depending on the type as well as the number of installations.

If you want a complete battery system to completely replace the common type of electricity, the installation cost will be between 15,000 - 40,000 USD (300 million - 1 billion VND). This number has become an obstacle, making solar batteries not be used in too many places.

The thing is that after installation is completed, the electricity bill will be significantly reduced, even becoming a past. And the good news is that solar cells will become cheaper and cheaper in the future.

2. Power generation efficiency is not high

Light from the Sun has many different wavelengths. Some wavelengths are too weak to produce photovoltaic phenomena, some are too strong for silicon - the main material that makes up solar cells.

Besides, dependence on nature to operate is also a weakness that is difficult to overcome. Battery for energy use directly but only works during the day. Moreover, just a few murky days of rain is the power to create electricity becomes a joke now.

The only solution is to buy a battery of electric storage, which costs a lot to equip and maintain.

3. Occupying a lot of space

Not all roofs and courtyards are large enough to fit the necessary battery.

Another reason that this system becomes a "luxury" non-family item can all be owned, is that it needs a large enough space to install. Technical experts agree that not all roofs and courtyards are large enough to fit the necessary battery.

4. Raw materials for making solar cells are quite rare

Many compounds to produce photovoltaics such as Telluride Cadmium (CdTe), Gallium Seliumide Indium (CIGS) . are difficult to find in nature. Therefore, mass production of solar cells is also quite difficult.

5. Environmental issues

Although still called the " green energy" but if you say that the solar cell completely does not produce any emissions is not true. The new production process or the process of disposing of old waste batteries all create toxic substances such as: Silicon Tetrachloride (SiCl ₄ ), Cadmium Telluride (CdTe), Sulfur Hexafluoride (SF ₆ ), Clohidric Acid (HCl) .

Some new generation batteries can reduce these wastes, but not completely. The next human goal is to make solar cells a truly green energy, really better for the environment than other traditional energies.
