Australia He has an invention that could mean the biggest change of the last decade. Renewable energy sources are of the utmost importance to separate ourselves from the dependence on fossil fuels, that is a fact. The most sustainable search for energies stimulates innovation and efficiency in solar cells, so that we make the way we benefit from the light of the Sol.
As the technology progresses, new materials and systems that can increase the energy conversion appear, reduce costs and minimize the impact of the environment. One of the inventions that gives the most to talk about in the current context is the solar panel, that the rays of the Sol To turn them into energy.
The efficiency of photovoltaic cells is an essential feature to determine the general efficiency of solar energy methods. It should be noted that the efficiency of a photovoltaic cell is the percentage of sunlight that can change into electricity. Australia He is aware of this procedure and has devised an invention that can change the energy sector.
Australia has the world record for photovoltaic efficiency
A group of researchers from the Unsw They have achieved the best brand of the world record of photovoltaic efficiency with a Kesterite solar cell (CZTS). This material can become the complement or replacement in the long term, sustainable and profitable for solar panels based on silicon.
It should be noted that experts from all over the world work day and night to find the best resource to combine conventional silicon cells to create a solar cell in tandem, which can increase efficiency compared to the solar cell of Unique Union. But it has been Australia The country that made the difference.
The Profesora de Scientia, Xiaojing Haoand his team of the Photovoltaic Engineering School and from Unaware of renewable energy They have achieved the best efficiency in the world of 13.2% for the solar chest cells of high -band prohibited, improved with hydrogen. Kesterite is a natural mineral.
However, it can also artificially develop at low costs by one mix With copper, zinc, tin and sulfur, abundant and non -toxic sources. This opens the door to new opportunities for solar panels to a horizon that have not even investigated the most striking inventions in the sector, such as the strange and powerful solar panel in history.
Australia breaks with conventional solar panels, which are on the limit
“The silicon modules have almost achieved the limit of their theoretical efficiency, so what we are trying to do is answer the question from the photovoltaic industry about what the next generation of cells will be made,” said the professor of Scientia Xiaojing HaoThat led the research team, according to the website of Academic Center.
There were earlier attempts to take advantage of the potential of Kesterite, but they were confronted with various obstacles for defects that were generated during the elaboration process. The Australia team knew that he had a major challenge and decided to tackle it with the help of a new approach that is considering hydrogen treatment.
They used the passive technology, which effectively neutralizes the harmful effects of defects and makes it possible for the Kesterite Solar Celon to transform sunlight into electricity with considerably improved efficiency. The advance reached by Australia It is based on 6 years of research.
Australia proposes the final solution for solar panels
In the beginning, the Australia experiment registered an efficiency of 11.4% for CZTS cells. Now, with hydrogen passiveness, they have surpassed the previous record. “The general panorama here is that we ultimately want to make electricity cheaper and more ecological to generate,” the professor appreciated Hao.
With this invention on the table, Australia It could promote the biggest change of the last decade. A change that would enable us to take a look in the future in advance and to overcome every expectation on technologies of this type, such as this solar panel smaller than an atom. It is 200 times more powerful than a renowned metal.
