How longer exciton lifetimes could ease efficiency trade-off in organic solar cells
Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the University of Potsdam, the Paul-Drude-Institut in Berlin and other collaborators has now demonstrated which physical processes limit a key parameter in the performance of organic solar cells. This opens up the possibility of …
Scientists uncover secret flaw holding back 20% organic solar cells
An international team of researchers has uncovered the hidden mechanism that limits the performance of organic solar cells and could help them exceed the 20 percent efficiency barrier. The study, led by scientists from Linköping University in Sweden, the University of Potsdam in Germany, and the Paul Drude Institute in Berlin, sheds light on a long-standing challenge in the development of organic photovoltaics (OPV). Organic photovoltaic solar c…
Organic solar cells have been considered a promising alternative to conventional silicon technology for years. They can be produced cost-effectively from earthy materials, are flexible and lightweight and are suitable for applications where rigid silicon panels are not eligible. However, a persistent efficiency limit slowed down their development: Beyond 20 percent efficiency, progress has stalled. An international research team has now identifi…
