A lab team led by Yasir Siddique, a Pakistani scientist, has created a promising solar cell technology that breaks two world records for efficiency in a laboratory.
The idea might help with the creation of clean energy programmes to combat global warming.
Yasir Siddique, a Ph.D. student at the Korea Institute of Energy Research (KIER) and Daejeon University of Science and Technology (UST), has designed and built Copper Indium Sulphur Selenide (CISSe) solar cells that have been solution-processed.
The low bandgap CISSe device works flawlessly as a single cell, but it might also be sandwiched with other thin-film solar cell materials with suitable bandgap as the top cell, such as Perovskite, a newly developed solar cell technology.
The bandgap is the amount of energy needed to free an electron from a semiconductor; the lower the bandgap, the more electricity is generated.
According to Express News, the sun will help generate enough power while also mitigating global warming in an environmentally friendly way.
The sandwich or tandem cell invented by Dr. Yasir is the most effective invention in the field of solar energy. The revolutionary cell is the result of three years of hard labour. Among them, only the CISSe cell has a 14.4 percent efficacy rate. When combined with the prosciutto mineral, the CISSe cell achieved a new record of 23.03 percent efficiency, which is a new high for a CISSE solar cell manufactured using the solution technique.
