Breakthrough in Solar Cell Technology
A team of scientists in South Korea has developed a new perovskite solar cell that delivers record-breaking efficiency and lasts more than three times longer than conventional versions.
The research, published in Nature Energy, was led by Professors Changduk Yang and Seung-Jae Shin from the School of Energy and Chemical Engineering at UNIST, in collaboration with Professor Hanul Min from Korea University.
The team achieved a certified power conversion efficiency of 25.8% (with a peak lab result of 26.2%) while solving one of perovskite solar cells’ biggest problems—poor long-term stability.
Perovskite solar cells have attracted tremendous attention over the past decade because they are inexpensive to produce and can reach very high efficiencies.
This breakthrough could help bring this promising solar technology closer to widespread use in real-world energy systems.
