What is perovskite?
Perovskite is a material with a crystal structure particular that allows you absorb light exceptionally. This compound can be formed by various elements, although in the photovoltaic field it usually contains lead, iodo y methylammonium.
Its great capacity of conversion of light into electricity has made it a promising alternative to silicon, the dominant material in the manufacture of traditional solar panels. Recent research has shown that perovskite solar cells can achieve efficiencies higher than 25%, which places them on par with, and even above, the silicon cells current.
How do perovskite solar cells work?
Perovskite solar cells work in a similar way to silicon cells. When receiving the sunlight, excite the electrons within the material, generating a electric currentHowever, the big difference lies in their composition and structure, which allow them to absorb different wavelengths of light, thus improving its efficiency.
In addition, manufacturing It is much simpler and cheaper, since it does not require high temperature processes as is the case with silicon. This is an important step towards a more accessible and sustainable solar energy.
Advantages of perovskite solar panels
- Greater efficiency: In laboratory tests, perovskite cells have achieved efficiencies greater than 25%, which makes them more effective than many conventional solar technologies.
- Lower production cost:The manufacture of these cells is cheaper than that of silicon, since they can be produced at lower temperatures and with simpler processes.
- Flexibility and lightness: Unlike rigid silicon panels, perovskite cells can be flexible and light, which allows its application in curved surfaces or even windows.
- greater versatility: Their structure and composition allow them to be used in different environments, included buildings y Power Plants.
Disadvantages and challenges of perovskite technology
- limited durability: One of the main problems with perovskite is its low stability. It degrades over time when exposed to light. moisture, heat and UV light.
- Presence of toxic materials: Most perovskite solar cells contain lead, a highly polluting material that is harmful to the environment and health.
- Lack of development at a commercial level: Although its efficiency is promising, processes for its use have not yet been developed. standardized manufacturing that allow for large-scale production.
Future applications of perovskite in solar energy
The future of perovskite solar cells is very promising. Researchers are exploring ways to improve their performance. durability and replace the lead by less toxic materials, such as tin. They are also developing tandem solar panels that combine perovskite with silicon to further improve efficiency.
In addition, its flexibility opens the door to innovative applications, such as solar windows, photovoltaic roofs y electronics devices with autonomous charging. If its main drawbacks can be solved, perovskite could change the way we use energy. solar energy.
Perovskite solar cells represent a technological leap in the world of photovoltaic energy. Although they still face important challenges, their efficiency and low production cost make them one of the most promising alternatives for the future of solar energy. If advances in durability and sustainability continue, we could be facing the next great revolution in the production of renewable energy.
