Tandem solar cells made from perovskite and organic material break efficiency record

Trying to improve the efficiency of solar cells to become independent from fossil energy sources is a major goal of solar cell research. A team led by physicist Dr. Felix Lang from the University of Potsdam, Prof. Lei Meng and Prof. Yongfang Li from the Chinese Academy of Sciences, Beijing, has now combined perovskite with organic absorbers to form a record-level tandem solar cell as reported in Nature.
