With the participation of an Egyptian .. "A global information earthquake" in the field of solar cells.

The new database was praised by senior researchers in the same field around the world, so Nature Energy, the world’s largest and largest research journal in the field of energy, published an article on the event. It’s an information earthquake.

Sky News Arabia Dr Mahmoud Aldamasi, To highlight the story of the database and its significance and its role in it with other researchers from many countries.

Eldamasi said he was working to develop a new type Solar cell It is called “pervoskyte” cells, and “although its photovoltaic properties were discovered in the middle of the last century, its first application in the field of solar cells was in 2009. Within a few years, its efficiency surpassed that of other technologies. Now commercially.

He added: “Perovskite cells have attracted a lot of interest from scientists because of the properties of the materials from which they are made, so you can design and modify their chemical composition so that they can absorb a certain portion of sunlight very efficiently. The preparation is very efficient and very cost effective in a short period of time as compared to the current silicon based technology.

There are still many challenges facing the materials, al-Damasi added PerovskiteAt the forefront of it is stability and shelf life, where its lifespan does not exceed 5 years, while silicon-based solar cells are stable for about 20 years.

The Egyptian researcher continued: “As a result of the world’s focus on perovskite solar cells, scientists from many disciplines have rushed to study them and to understand the mechanisms of transmission of electrons and charges within them. A promising type of cell, but this rapid development has posed a great challenge to scientists working in this field, as no one can pursue it, and because of this large amount of published research and continuous track of scientific development, researchers cannot be aware of everything that happens in their specialization. Caused by.

Al-Damasi said: “In this context, a team of researchers led by Dr. Eva Unger of the Helmholtz-Berlin Institute for Energy and Materials in Germany decided to create an open source global science database, which collects and publishes data on each solar cell made using this technology and published on each cell cell built using this technology. He gave a number of introductory speeches to present in a interactive information format and to attract young researchers from top universities and research centers to join the project. ”

In fact, more than 80 researchers, including L-Damasi from the Egyptian Petroleum Research Institute, were convinced of the idea, and from the end of 2019 to the middle of 2020, these researchers read more than 20,000 scientific papers published in the field. Al-Damasi confirmed that 100 information about each of the total 42,200 solar cells have been published in the region, which puts us in front of millions of accurate scientific data. That’s a rare database. “

Al-Damasi stressed, “The importance of this information base lies in the fact that it provides information that was previously difficult or impossible to obtain. Takes an extract, which was impossible before developing the mentioned database.

He explained, “Furthermore, this database is considered a goldmine for machine learning scientists because they can program certain algorithms that swallow such large amounts of data and infer from them the future directions for developing such a solar cell. We can tell that the algorithms are excellent.” Chemical compositions In order to achieve the highest stability and longevity of the cells that produce it, we must rely on solar cells to achieve the highest possible efficiency and the best architecture possible, after publishing research in a paper published in the journal Nature Energy, which contains several other findings that are currently being studied by an army of scientists.

Al-Damasi is an Egyptian researcher at the Petroleum Research Institute in Cairo and the Helmholtz Berlin Institute for Energy and Materials in Germany. Worked as an assistant researcher in the field of petroleum additives, while working there he contributed to the development of several additives. Egypt.

After graduating, Al-Damasi completely changed his specialization and decided to go to Germany to pursue a doctorate in one of the newest and fastest growing fields of solar cells and to join the group of one of the best professors, Professor Antonio Abbott. He has published approximately 17 research papers in the field worldwide, and in less than 3 years. Scientific conferences in the same specialty.

She has also participated in the Al-Damasi Educational Clinic Foundation, providing counseling and guidance to many Egyptian and Arab students seeking scholarships abroad.
