Pakistan is home to extraordinary people. On many accounts, we have seen Pakistanis setting world records. They lay some remarkable groundwork for others to follow. These Pakistanis bring pride and respect to Pakistan. This is exactly what happened when a Pakistani scientist set two world records in solar technology.
A Pakistani scientist, Yasir Siddique made to the headlines of Neemopani because of his work. Yasir is a Ph.D. student at the Daejeon University of Science and Technology (UST). He worked at the Korea Institute of Energy Research (KIER) to design and produce the solution-based Copper Indium Sulfur Selenide (CISSe) solar cells.
We know it’s hard to understand the confusing technical terms but tension nahien leni hum hain na. We’ll tell you what actually this invention would be used for and why it made it to the list of world records.
About the technology
First thing, you need to know about the conversion of solar energy by solar cells. The CISSe solar cells convert solar energy to electrical energy. However, these solar cells convert a lower amount of solar energy to electrical as compared to the amount of solar energy they are absorbing. So, CISSe solar cells have to be efficient enough to convert more amount of solar energy into electrical energy. The energy needed in this conversion process is called a bandgap. Yasir manufactured a solution-processed single cell with 14.4 percent efficiency. Before this invention, CISSe solar cells developed were 13.5 percent efficient. Moreover, Yasir Siddique developed this technology in such a way that its efficiency could be enhanced to 23.03 percent when the cell is attached to some prosciutto mineral.
Moreover, this technology is environmentally friendly and also will help reduce global warming. This is indeed a revolutionary cell. Yasir while addressing to the questions related to the invention said “The stable solution-processed device works perfectly as a single cell but it could also be linked with other thin-film solar cell materials with sufficient bandgap as the top cell. The bandgap is the amount of energy required to liberate an electron from a semiconductor; the smaller the bandgap, the more electricity is produced.”
It is also said to be one of the impactful inventions by KIER according to Yasir’s statement: “It is the single largest high impact research published from KIER, Daejeon Campus in recent times.”
It took almost three years for Yasir Siddique and his team to produce the CISSe solar cell. No doubt his hard work and efforts paid off pretty well. We are proud of you Yasir Siddique and wish you the best of luck for your future endeavors.
