Pakistani Scientist sets two World Records in Solar cell Technology

In the lab, a team lead by Pakistani scientists produced a promising solar cell technique that broke two world records for efficiency.

The strategy could aid in the development of clean energy programmes to counteract global warming.

A solution-processed Copper Indium Sulphu Selenide (CISSe) solar cells has been designed and manufactured by Yasir Siddique, a PhD student at the Korea Institute of Energy Research (KIER) and the Daejeon University of Science and Technology (UST).

The stable solution-processed, low bandgap CISSe device works perfectly as a single cell, but it could also be sandwiched with other thin-film solar cell materials with sufficient bandgap as the top cell, such as Perovskite, a recently developed solar cell technology.

The bandgap is the amount of energy required to liberate an electron from a semiconductor; the smaller the bandgap, the more electricity is Produced.
